Orange: - Sunday merger with bf-blender - Foundations for new Node editor in Blender, generic framework that can be used for Material/Texture, Compositing, Logic or maybe even Sequencer. Note: this doesn't do anything yet, nor save! Is just to get this nice in CVS now. :)

Custom Names for Nodes This commit makes it possible to add a custom name to a node. The feature can be accessed either by using a menu or shortcut ctrl-r. It currently works only when a single node is selected. Invoking the feature gives a popup menu in which a new name can be entered. If the given name is not empty, it will be shown like "(myCustomName) NodeName" in the node header. This feature is particularly useful when documenting complex node setups. I also fixed the size of blur node. It was too short before due to my previous commit. Thanks to David Millan Escriva for contribution!

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

#include "DNA_userdef_types.h"
Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

== Grease Pencil == Grease Pencil is a tool which allows you to draw freehand in some views, allowing you to annotate/scribble over the contents of that view in either 2d or 3d. This facilitates many easier communication and planning abilities. To use, simply enable it from the View menu (choose 'Grease Pencil...' and click 'Use Grease Pencil'). Then, click+drag using the left-mouse button and the shift-key held to draw a stroke. For more information, check the following page on the wiki: http://wiki.blender.org/index.php/User:Aligorith/247_Grease_Pencil

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons.

Orange: - Sunday merger with bf-blender - Foundations for new Node editor in Blender, generic framework that can be used for Material/Texture, Compositing, Logic or maybe even Sequencer. Note: this doesn't do anything yet, nor save! Is just to get this nice in CVS now. :)

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall.

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

features & fixes: - Enabled Groups to execute in Compositor. They were ignored still. Note; inside of groups nothing is cached, so a change of a group input will recalculate it fully. This is needed because groups are linked data (instances use same internal nodes). - Made Composit node "Viewer" display correctly input for images with 1/2/3/4 channels. - Added pass rendering, tested now with only regular Materials. For Material nodes this is quite more complex... since they cannot be easily separated in passes (each Material does a full shade) In this commit all pass render is disabled though, will continue work on that later. Sneak preview: http://www.blender.org/bf/rt.jpg (temporal image) - What did remain is the 'Normal' pass output. Normal works very nice for relighting effects. Use the "Normal Node" to define where more or less light should be. (Use "Value Map" node to tweak influence of the Normal node 'dot' output.) - EVIL bug fix: I've spend almost a day finding it... when combining AO and mirror render, the event queue was totally screwing up... two things not related at all! Found out error was in ray-mirror code, which was using partially uninitialized 'ShadeInput' data to pass on to render code. - Another fix; made sure that while thread render, the threads don't get events, only the main program will do.

Seems a large commit, but I also changed function names to match the new naming convention for Compositing: - Render Result node -> Render Layers node (name only appears in Add menu) - Compositor image -> Viewer Node image I've also added a version patch (2.41 saved files only) to rename existing "Compositor" Images.

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)
2005-12-29 18:08:01 +00:00
switch(event) {
Orange: - New UI element: the "Curve Button". For mapping ranges (like 0 - 1) to another range, the curve button can be used for proportional falloff, bone influences, painting density, etc. Most evident use is of course to map RGB color with curves. To be able to use it, you have to allocate a CurveMapping struct and pass this on to the button. The CurveMapping API is in the new C file blenkernel/intern/colortools.c It's as simple as calling: curvemap= curvemapping_add(3, 0, 0, 1, 1) Which will create 3 curves, and sets a default 0-1 range. The current code only supports up to 4 curves maximum per mapping struct. The CurveMap button in Blender than handles allmost all editing. Evaluating a single channel: float newvalue= curvemapping_evaluateF(curvemap, 0, oldval); Where the second argument is the channel index, here 0-1-2 are possible. Or mapping a vector: curvemapping_evaluate3F(curvemap, newvec, oldvec); Optimized versions for byte or short mapping is possible too, not done yet. In butspace.c I've added a template wrapper for buttons around the curve, to reveil settings or show tools; check this screenie: http://www.blender.org/bf/curves.jpg - Buttons R, G, B: select channel - icons + and -: zoom in, out - icon 'wrench': menu with tools, like clear curve, set handle type - icon 'clipping': menu with clip values, and to dis/enable clipping - icon 'x': delete selection In the curve button itself, only LMB clicks are handled (like all UI elements in Blender). - click on point: select - shift+click on point: swap select - click on point + drag: select point (if not selected) and move it - click outside point + drag: translate view - CTRL+click: add new point - hold SHIFT while dragging to snap to grid (Yes I know... either one of these can be Blender compliant, not both!) - if you drag a point exactly on top of another, it merges them Other fixes: - Icons now draw using "Safe RasterPos", so they align with pixel boundary. the old code made ints from the raster pos coordinate, which doesn't work well for zoom in/out situations - bug in Node editing: buttons could not get freed, causing in memory error prints at end of a Blender session. That one was a very simple, but nasty error causing me all evening last night to find! (Hint; check diff of editnode.c, where uiDoButtons is called) Last note: this adds 3 new files in our tree, I did scons, but not MSVC!

I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window.

(well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall.

Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

* Merge of PyNodes to trunk. Finally! See http://wiki.blender.org/index.php/BlenderDev/PyNodes and http://wiki.blender.org/index.php/BlenderDev/PyNodes/API For current documentation. Very very big thanks go to William Germano for fixing the memory issues left and for improving on the code. In the coming time documentation will be finalised and further stabilising of PyNodes is to be expected.

in= nodeAddNodeType(sce->nodetree, CMP_NODE_R_LAYERS, NULL, NULL);
A couple of render improvements; - Bug fix: the upper tile in a collumn for Panorama render didn't put the mainthread to sleep properly. Now panorama renders 25% faster if you had set Y-Parts to 4. - Enabling Compositing in Scene for first time now adds a "Composite" node too, so render output gets applied. - An attempt to render with "Do Composite" without "Composite" node will throw an error and stops rendering. In background mode it will just not render at all, and print errors. - Errors that prevent rendering now give a popup menu again. - Having MBlur or Fields option on will now normally render, but with an error print in console (not done yet...)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

/* Here we set the active tree(s), even called for each redraw now, so keep it fast :) */
Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Orange; maintenance commit! - Moved all 'render pipeline control' options out of the Material panels into the (now renamed) "Links and Pipeline" Panel. These are the options that are not per material-node, but global for the entire Material tree. It includes ZTransp, Zinvert, Strands, Halo, Wire, etc. - To further make Node editing clear, when you enable Nodes for the first time, the link button to the first Material node is drawn red, to note that here needs something linked or added. - Protected Node editing for Library data - Fixed header buttons to work OK for Node Window

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image().

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange; more render & compo stuff! -> Rendering in RenderLayers It's important to distinguish a 'render layer' from a 'pass'. The first is control over the main pipeline itself, to indicate what geometry is being is rendered. The 'pass' (not in this commit!) is related to internal shading code, like shadow/spec/AO/normals/etc. Options for RenderLayers now are: - Indicate which 3d 'view layers' have to be included (so you can render front and back separately) - "Solid", all solid faces, includes sky at the moment too - "ZTransp", all transparent faces - "Halo", the halos - "Strand", the particle strands (not coded yet...) Currently only 2 'passes' are exported for render, which is the "Combined" buffer and the "Z. The latter now works, and can be turned on/off. Note that all layers are still fully kept in memory now, saving the tiles and layers to disk (in exr) is also todo. -> New Blur options The existing Blur Node (compositor) now has an optional input image. This has to be a 'value buffer', which can be a Zbuffer, or any mask you can think of. The input values have to be in the 0-1 range, so another new node was added too "Map Value". The value input can also be used to tweak blur size with the (todo) Time Node. Temporal screenies: http://www.blender.org/bf/rt.jpg http://www.blender.org/bf/rt1.jpg http://www.blender.org/bf/rt2.jpg BTW: The compositor is very slow still, it recalulates all nodes on each change still.

Orange; more render & compo stuff! -> Rendering in RenderLayers It's important to distinguish a 'render layer' from a 'pass'. The first is control over the main pipeline itself, to indicate what geometry is being is rendered. The 'pass' (not in this commit!) is related to internal shading code, like shadow/spec/AO/normals/etc. Options for RenderLayers now are: - Indicate which 3d 'view layers' have to be included (so you can render front and back separately) - "Solid", all solid faces, includes sky at the moment too - "ZTransp", all transparent faces - "Halo", the halos - "Strand", the particle strands (not coded yet...) Currently only 2 'passes' are exported for render, which is the "Combined" buffer and the "Z. The latter now works, and can be turned on/off. Note that all layers are still fully kept in memory now, saving the tiles and layers to disk (in exr) is also todo. -> New Blur options The existing Blur Node (compositor) now has an optional input image. This has to be a 'value buffer', which can be a Zbuffer, or any mask you can think of. The input values have to be in the 0-1 range, so another new node was added too "Map Value". The value input can also be used to tweak blur size with the (todo) Time Node. Temporal screenies: http://www.blender.org/bf/rt.jpg http://www.blender.org/bf/rt1.jpg http://www.blender.org/bf/rt2.jpg BTW: The compositor is very slow still, it recalulates all nodes on each change still. Persistant memory and dependency checks is coming!

void snode_make_group_editable(SpaceNode *snode, bNode *gnode)
Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Group Nodes made functional: each group now can be re-used (instanced) with SHIFT+G. This works as well for local groups as library-linked groups. Also fixed that group nodes were copying internal data to the outside, which made it impossible to use the socket-buttons to set individual values for each group-instance. Library-linked groups are prevented from editing. But, try to open a group and it will give a request for 'make local'. The make local rule is identical to other library data in blender, meaning: - if all users of the library data are local -> the library data is flagged 'local', and if needed a unique name is made - if there's mixed users (local and from other library data) it makes a full copy, and assigns this copy to all local users.

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor.

Group Nodes made functional: each group now can be re-used (instanced) with SHIFT+G. This works as well for local groups as library-linked groups. Also fixed that group nodes were copying internal data to the outside, which made it impossible to use the socket-buttons to set individual values for each group-instance. Library-linked groups are prevented from editing. But, try to open a group and it will give a request for 'make local'. The make local rule is identical to other library data in blender, meaning: - if all users of the library data are local -> the library data is flagged 'local', and if needed a unique name is made - if there's mixed users (local and from other library data) it makes a full copy, and assigns this copy to all local users.

Orange: - Sunday merger with bf-blender - Foundations for new Node editor in Blender, generic framework that can be used for Material/Texture, Compositing, Logic or maybe even Sequencer. Note: this doesn't do anything yet, nor save! Is just to get this nice in CVS now. :)

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Custom Names for Nodes This commit makes it possible to add a custom name to a node. The feature can be accessed either by using a menu or shortcut ctrl-r. It currently works only when a single node is selected. Invoking the feature gives a popup menu in which a new name can be entered. If the given name is not empty, it will be shown like "(myCustomName) NodeName" in the node header. This feature is particularly useful when documenting complex node setups. I also fixed the size of blur node. It was too short before due to my previous commit. Thanks to David Millan Escriva for contribution!

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange: daily noodle updates; - Texture Node: now displays 'intensity values' in node too, and has input, and shows in buttons when activated in Node editor. (no browsing buttons yet...) - New: "Normal Node". This uses a new UI button, which allows to quickly input a normal vector, based on spherical coordinates. The Normal Node has optional vector input, and delivers a dot product then. This can be used as a blending factor between nodes, or for fake extra light in a certain direction. - New: "Geometry Node". This actually replaces the Input node. It offers all coordinates (vectors) as being the starting point for shading and for textures. Note: for preview render this doesn't give much different results yet... this is the start for real render support! - http://www.blender.org/bf/rt5.jpg The two new nodes in action - Bugfix: the "Block" button (which delivers popups) did not return a correct event when nothing happened (mouse moved out), which could cause mouse clicks to be passed on to the queue.

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Plumiferos request Compositor: Viewer Nodes inside of Groups now work too. To not frustrate interactive speed, the following rules apply: - Making a Group editable (or closing) doesn't signal recalculation of composite - clicking on an Input socket always checks changes and calulcates - When there are Viewers inside an edited Group, Viewers in the main tree are not executed. Also added: a "hide unused sockets" icon in the header of Viewer nodes. This allows cleanup of Groups, to prevent these sockets get reveiled.

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them.

/* can be called from menus too, but they should do own undopush and redraws */
Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

Node editor: when adding a new node, automatic links are created: - from all selected nodes - only connections between highest order socket types; so if there's RGBA and Value sockets, only RGBA sockets are connected. This because in these cases the Value sockets usually are for user input. Example: Mix node. Thanks Trip for the hint!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended).

Node editing usablity! - Removed stupid idea to insert convertor nodes in Node Shaders, when a link is created by non-matching sockets. Now it works like Compositor, doing a default conversion. Works like this: 1 from 3 or 4 values: take average 3 from 1: copy to all 3 from 4: copy 3 4 from 1: copy to 3, set alpha to 1 4 from 3: copy 3, set alpha to 1 - Added select-linked in Nodes.

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

Fix for bug #7875: node editor creates links to nowhere, fixes at least one instance where it happens, when dragging a link onto an already taken socket, and the existing link being moved to a hidden socket. Couldn't find other cases in testing, so assuming it's fixed unless another case pops up.

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks.

Two hours of fixing details based on Klocwork source review. Useful report, although it has a lot of noise. Not to mention our bad string code gives a load of warnings. I've reviewed specifically: - file reading/write - dna and library code - node system - entire render module Done a couple of files in src/ too, seemed to be nice errors.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks.

/* we might need to remove a link */
Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks.

A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block.

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Conversion of "Toggle Link" tool to "Make Link" This commit alters the behaviour of "Toggle Link" tool found in the node editor so that it only makes link between selected sockets. Links cannot be deleted by using the tool again as before. Instead deleting links can be done by using the old method (drag with lmb). The delete functionality may require further investigation to see if it should be improved.

Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

[#17433] Cannot break node links with LMB drag under linux. Grease pencil commit added some panel draw code or whatnot which seems to change the matrix stack in unwanted (in this case) ways. Reset to identity fixes it. * I don't think it was limited to Linux though

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Fix for bug #7406 'Compositor Crash' Previously when deleting a scene, no checks were made to see if any render layer nodes in other scenes were referencing them, leaving them pointing to bad memory.

Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

/* ********************** */
Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange; more render & compo stuff! -> Rendering in RenderLayers It's important to distinguish a 'render layer' from a 'pass'. The first is control over the main pipeline itself, to indicate what geometry is being is rendered. The 'pass' (not in this commit!) is related to internal shading code, like shadow/spec/AO/normals/etc. Options for RenderLayers now are: - Indicate which 3d 'view layers' have to be included (so you can render front and back separately) - "Solid", all solid faces, includes sky at the moment too - "ZTransp", all transparent faces - "Halo", the halos - "Strand", the particle strands (not coded yet...) Currently only 2 'passes' are exported for render, which is the "Combined" buffer and the "Z. The latter now works, and can be turned on/off. Note that all layers are still fully kept in memory now, saving the tiles and layers to disk (in exr) is also todo. -> New Blur options The existing Blur Node (compositor) now has an optional input image. This has to be a 'value buffer', which can be a Zbuffer, or any mask you can think of. The input values have to be in the 0-1 range, so another new node was added too "Map Value".

Orange: - Sunday merger with bf-blender - Foundations for new Node editor in Blender, generic framework that can be used for Material/Texture, Compositing, Logic or maybe even Sequencer. Note: this doesn't do anything yet, nor save! Is just to get this nice in CVS now. :)
2005-12-18 13:46:01 +00:00
Orange: - New UI element: the "Curve Button". For mapping ranges (like 0 - 1) to another range, the curve button can be used for proportional falloff, bone influences, painting density, etc. Most evident use is of course to map RGB color with curves. To be able to use it, you have to allocate a CurveMapping struct and pass this on to the button. The CurveMapping API is in the new C file blenkernel/intern/colortools.c It's as simple as calling: curvemap= curvemapping_add(3, 0, 0, 1, 1) Which will create 3 curves, and sets a default 0-1 range. The current code only supports up to 4 curves maximum per mapping struct. The CurveMap button in Blender than handles allmost all editing. Evaluating a single channel: float newvalue= curvemapping_evaluateF(curvemap, 0, oldval); Where the second argument is the channel index, here 0-1-2 are possible. Or mapping a vector: curvemapping_evaluate3F(curvemap, newvec, oldvec); Optimized versions for byte or short mapping is possible too, not done yet. In butspace.c I've added a template wrapper for buttons around the curve, to reveil settings or show tools; check this screenie: http://www.blender.org/bf/curves.jpg - Buttons R, G, B: select channel - icons + and -: zoom in, out - icon 'wrench': menu with tools, like clear curve, set handle type - icon 'clipping': menu with clip values, and to dis/enable clipping - icon 'x': delete selection In the curve button itself, only LMB clicks are handled (like all UI elements in Blender). - click on point: select - shift+click on point: swap select - click on point + drag: select point (if not selected) and move it - click outside point + drag: translate view - CTRL+click: add new point - hold SHIFT while dragging to snap to grid (Yes I know... either one of these can be Blender compliant, not both!) - if you drag a point exactly on top of another, it merges them Other fixes: - Icons now draw using "Safe RasterPos", so they align with pixel boundary. the old code made ints from the raster pos coordinate, which doesn't work well for zoom in/out situations - bug in Node editing: buttons could not get freed, causing in memory error prints at end of a Blender session. That one was a very simple, but nasty error causing me all evening last night to find! (Hint; check diff of editnode.c, where uiDoButtons is called) Last note: this adds 3 new files in our tree, I did scons, but not MSVC!

/* special version to prevent overlapping buttons, has a bit of hack... */
Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

Solved bad design decision in Node Editor: The buttons uiBlock was stored in a Node, for retrieval of node buttons, however that won't work when multiple windows show same Nodes.

static int node_uiDoBlocks(ScrArea *sa, short event)
More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Orange: daily noodle updates; - Texture Node: now displays 'intensity values' in node too, and has input, and shows in buttons when activated in Node editor. (no browsing buttons yet...) - New: "Normal Node". This uses a new UI button, which allows to quickly input a normal vector, based on spherical coordinates. The Normal Node has optional vector input, and delivers a dot product then. This can be used as a blending factor between nodes, or for fake extra light in a certain direction. - New: "Geometry Node". This actually replaces the Input node. It offers all coordinates (vectors) as being the starting point for shading and for textures. Note: for preview render this doesn't give much different results yet... this is the start for real render support! - http://www.blender.org/bf/rt5.jpg The two new nodes in action - Bugfix: the "Block" button (which delivers popups) did not return a correct event when nothing happened (mouse moved out), which could cause mouse clicks to be passed on to the queue.

Orange; more render & compo stuff! -> Rendering in RenderLayers It's important to distinguish a 'render layer' from a 'pass'. The first is control over the main pipeline itself, to indicate what geometry is being is rendered. The 'pass' (not in this commit!) is related to internal shading code, like shadow/spec/AO/normals/etc. Options for RenderLayers now are: - Indicate which 3d 'view layers' have to be included (so you can render front and back separately) - "Solid", all solid faces, includes sky at the moment too - "ZTransp", all transparent faces - "Halo", the halos - "Strand", the particle strands (not coded yet...) Currently only 2 'passes' are exported for render, which is the "Combined" buffer and the "Z. The latter now works, and can be turned on/off. Note that all layers are still fully kept in memory now, saving the tiles and layers to disk (in exr) is also todo. -> New Blur options The existing Blur Node (compositor) now has an optional input image. This has to be a 'value buffer', which can be a Zbuffer, or any mask you can think of. The input values have to be in the 0-1 range, so another new node was added too "Map Value". The value input can also be used to tweak blur size with the (todo) Time Node. Temporal screenies: http://www.blender.org/bf/rt.jpg http://www.blender.org/bf/rt1.jpg http://www.blender.org/bf/rt2.jpg BTW: The compositor is very slow still, it recalulates all nodes on each change still. Persistant memory and dependency checks is coming!

== Grease Pencil == Grease Pencil is a tool which allows you to draw freehand in some views, allowing you to annotate/scribble over the contents of that view in either 2d or 3d. This facilitates many easier communication and planning abilities. To use, simply enable it from the View menu (choose 'Grease Pencil...' and click 'Use Grease Pencil'). Then, click+drag using the left-mouse button and the shift-key held to draw a stroke.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange: - New UI element: the "Curve Button". For mapping ranges (like 0 - 1) to another range, the curve button can be used for proportional falloff, bone influences, painting density, etc. Most evident use is of course to map RGB color with curves. To be able to use it, you have to allocate a CurveMapping struct and pass this on to the button. The CurveMapping API is in the new C file blenkernel/intern/colortools.c It's as simple as calling: curvemap= curvemapping_add(3, 0, 0, 1, 1) Which will create 3 curves, and sets a default 0-1 range. The current code only supports up to 4 curves maximum per mapping struct. The CurveMap button in Blender than handles allmost all editing. Evaluating a single channel: float newvalue= curvemapping_evaluateF(curvemap, 0, oldval); Where the second argument is the channel index, here 0-1-2 are possible. Or mapping a vector: curvemapping_evaluate3F(curvemap, newvec, oldvec); Optimized versions for byte or short mapping is possible too, not done yet. In butspace.c I've added a template wrapper for buttons around the curve, to reveil settings or show tools; check this screenie: http://www.blender.org/bf/curves.jpg - Buttons R, G, B: select channel - icons + and -: zoom in, out - icon 'wrench': menu with tools, like clear curve, set handle type - icon 'clipping': menu with clip values, and to dis/enable clipping - icon 'x': delete selection In the curve button itself, only LMB clicks are handled (like all UI elements in Blender). - click on point: select - shift+click on point: swap select - click on point + drag: select point (if not selected) and move it - click outside point + drag: translate view - CTRL+click: add new point - hold SHIFT while dragging to snap to grid (Yes I know... either one of these can be Blender compliant, not both!) - if you drag a point exactly on top of another, it merges them Other fixes: - Icons now draw using "Safe RasterPos", so they align with pixel boundary. the old code made ints from the raster pos coordinate, which doesn't work well for zoom in/out situations - bug in Node editing: buttons could not get freed, causing in memory error prints at end of a Blender session. That one was a very simple, but nasty error causing me all evening last night to find! (Hint; check diff of editnode.c, where uiDoButtons is called) Last note: this adds 3 new files in our tree, I did scons, but not MSVC!

In butspace.c I've added a template wrapper for buttons around the curve, to reveil settings or show tools; check this screenie: http://www.blender.org/bf/curves.jpg - Buttons R, G, B: select channel - icons + and -: zoom in, out - icon 'wrench': menu with tools, like clear curve, set handle type - icon 'clipping': menu with clip values, and to dis/enable clipping - icon 'x': delete selection In the curve button itself, only LMB clicks are handled (like all UI elements in Blender). - click on point: select - shift+click on point: swap select - click on point + drag: select point (if not selected) and move it - click outside point + drag: translate view - CTRL+click: add new point - hold SHIFT while dragging to snap to grid (Yes I know... either one of these can be Blender compliant, not both!) - if you drag a point exactly on top of another, it merges them Other fixes: - Icons now draw using "Safe RasterPos", so they align with pixel boundary. the old code made ints from the raster pos coordinate, which doesn't work well for zoom in/out situations - bug in Node editing: buttons could not get freed, causing in memory error prints at end of a Blender session. That one was a very simple, but nasty error causing me all evening last night to find! (Hint; check diff of editnode.c, where uiDoButtons is called) Last note: this adds 3 new files in our tree, I did scons, but not MSVC!

Orange: daily noodle updates; - Texture Node: now displays 'intensity values' in node too, and has input, and shows in buttons when activated in Node editor. (no browsing buttons yet...) - New: "Normal Node". This uses a new UI button, which allows to quickly input a normal vector, based on spherical coordinates. The Normal Node has optional vector input, and delivers a dot product then. This can be used as a blending factor between nodes, or for fake extra light in a certain direction. - New: "Geometry Node". This actually replaces the Input node. It offers all coordinates (vectors) as being the starting point for shading and for textures. Note: for preview render this doesn't give much different results yet... this is the start for real render support! - http://www.blender.org/bf/rt5.jpg The two new nodes in action - Bugfix: the "Block" button (which delivers popups) did not return a correct event when nothing happened (mouse moved out), which could cause mouse clicks to be passed on to the queue.

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

More node goodies! First note; this is a WIP project, some commits might change things that make formerly saved situations not to work identically... like now! ------ New Material integration ------ Until now, the Node system worked on top of the 'current' Material, just like how the Material Layers worked. That's quite confusing in practice, especially to see what Material is a Node, or what is the "base material" Best solution is to completely separate the two. This has been implemented as follows now; - The confusing "Input" node has been removed. - When choosing a Material in Blender, you can define this Material to be either 'normal' (default) or be the root of a Node tree. - If a Material is a Node tree, you have to add Nodes in the tree to see something happen. An empty Node tree doesn't do anything (black). - If a Material is a Node Tree, the 'data browse' menus show it with an 'N' mark before the name. The 'data block' buttons display it with the suffix 'NT' (instead of 'MA'). - In a Node Tree, any Material can be inserted, including itself. Only in that case the Material is being used itself for shading. UI changes: Added a new Panel "Links", which shows: - where the Material is linked to (Object, Mesh, etc) - if the Material is a NodeTree or not - the actual active Material in the Tree The "Node" Panel itself now only shows buttons from the other nodes, when they are active. Further the Material Nodes themselves allow browsing and renaming or adding new Materials now too. Second half of today's work was cleaning up selection when the Nodes overlap... it was possible to drag links from invisible sockets, or click headers for invisible nodes, etc. This because the mouse input code was not checking for visibility yet. Works now even for buttons. :)

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Four-in-one commit: (NOTE: new include dependency in Render module, might need MSVC update! It has to include the imbuf/intern/openexr/ directory in search path) -> New Composite node: "Hue Saturation". Works like the former 'post process' menu. There's no gamma, brightness or multiply needed in this node, for that the Curves Node functions better. -> Enabled Toolbox in Node editor This now also replaces the SHIFT+A for adding nodes. The nodes are automatically added to the menus, using the 'class' category from the type definition. Current classes are (compositor examples): Inputs: RenderResult, Image Outputs: Composite, Viewer Color Ops: RGB Curves, Mix, Hue Saturation, AlphaOver Vector Ops: Normal, Vector Curves, Map Value Filters: Filter, Blur, VectorBlur Convertors: ColorRamp, RGBtoBW, Separate RGBA, Separate HSVA, Set Alpha Generators: RGB, Value, Time Groups: the list of custom defined nodes -> OpenEXR tile saving support Created an API for for saving tile-based Images with an unlimited amount of layers/channels. I've tested it for 'render result' now, with the idea that this can (optionally) replace the current inserting of tiles in the main result buffers. Especially with a lot of layers, the used memory for these buffers can easily go into the 100s of megs. Two other advantages: - all 'render result' layers can be saved entirely in a single file, for later use in compositing, also for animation output. - on each render, per scene, a unique temp file can be stored, allowing to re-use these temp files on starting Blender or loading files, showing the last result of a render command. The option is currently disabled, needs more work... but I had to commit this because of the rest of the work I did! -> Bug fix The Image node didn't call an execute event when browsing another image.

This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

Group Nodes made functional: each group now can be re-used (instanced) with SHIFT+G. This works as well for local groups as library-linked groups. Also fixed that group nodes were copying internal data to the outside, which made it impossible to use the socket-buttons to set individual values for each group-instance. Library-linked groups are prevented from editing. But, try to open a group and it will give a request for 'make local'. The make local rule is identical to other library data in blender, meaning: - if all users of the library data are local -> the library data is flagged 'local', and if needed a unique name is made - if there's mixed users (local and from other library data) it makes a full copy, and assigns this copy to all local users.

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)
