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.

Fix T39735: New auto smooth creates artifacts with flat shaded faces(BI) This actually had nothing specific to new split normals, it was an internal limitation of BI raytracer, which would check against neighbor face shadowing only when they shared a common vertex, now it also performs checks when both faces have a vertex with a common "ancestor" (org index). Note this allows to also fix same issue when using SplitEdges modifier (and potentially others?), but only when AutoSmooth is enabled (due to some compute/mem overhead, we do not want to enable this code systematically). Thanks to Brecht for advices and review!

iImage based Vector Blur After a couple of experiments with variable blur filters, I tried a more interesting, and who knows... original approach. :) First watch results here: http://www.blender.org/bf/rt0001_0030.avi http://www.blender.org/bf/hand0001_0060.avi These are the steps in producing such results: - In preprocess, the speed vectors to previous and next frame are calculated. Speed vectors are screen-aligned and in pixel size. - while rendering, these vectors get calculated per sample, and accumulated in the vector buffer checking for "minimum speed". (on start the vector buffer is initialized on max speed). - After render: - The entire image, all pixels, then is converted to quad polygons. - Also the z value of the pixels is assigned to the polygons - The vertices for the quads use averaged speed vectors (of the 4 corner faces), using a 'minimum but non-zero' speed rule. This minimal speed trick works very well to prevent 'tearing' apart when multiple faces move in different directions in a pixel, or to be able to separate moving pixels clearly from non-moving ones - So, now we have a sort of 'mask' of quad polygons. The previous steps guaranteed that this mask doesn't have antialias color info, and has speed vectors that ensure individual parts to move nicely without tearing effects. The Z allows multiple layers of moving masks. - Then, in temporal buffer, faces get tagged if they move or not - These tags then go to an anti-alias routine, which assigns alpha values to edge faces, based on the method we used in past to antialias bitmaps (still in our code, check the antialias.c in imbuf!) - finally, the tag buffer is used to tag which z values of the original image have to be included (to allow blur go behind stuff). - OK, now we're ready for accumulating! In a loop, all faces then get drawn (with zbuffer) with increasing influence of their speed vectors. The resulting image then is accumulated on top of the original with a decreasing weighting value. It sounds all quite complex... but the speed is still encouraging. Above images have 64 mblur steps, which takes about 1-3 seconds per frame. Usage notes: - Make sure the render-layer has passes 'Vector' and 'Z' on. - add in Compositor the VectorBlur node, and connect the image, Z and speed to the inputs. - The node allows to set amount of steps (10 steps = 10 forward, 10 back). and to set a maximum speed in pixels... to prevent extreme moving things to blur too wide.

Added names to UV and vertex color layers, and display them as a list. Added support for multiple UVs in the render engine. This also involved changing the way faces are stored, to allow data to be added optionally per 256 faces, same as the existing system for vertices. A UV layer can be specified in the Map Input panel and the Geometry node by name. Leaving this field blank will default to the active UV layer. Also added sharing of face selection and hiding between UV layers, and at the same time improved syncing with editmode selection and hiding. Still to do: - Multi UV support for fastshade. - Multires and NMesh preservation of multiple UV sets.

Particles ========= - Fix crash in particle transform with the particle system not editable. - Particle child distribution and caching is now multithreaded. - Child particles now have a separate Render Amount next to the existing Amount. The render amount particles are now only distributed and cached at render time, which should make editing with child particles faster. - Two new options for diffuse strand shading: - Surface Diffuse: computes the strand normal taking the normal at the surface into account. - Blending Distance: the distance in Blender units over which to blend in the normal at the surface. - Special strand rendering for more memory efficient and faster hair and grass. This is a work in progress, and has a number of known issues, don't report bugs to me for this feature yet. More info: http://www.blender.org/development/current-projects/changes-since-244/particles/

Render Instancing ================= Big commit, but little user visible changes. - Dupliverts and duplifaces are now rendered as instances, instead of storing all of the geometry for each dupli, now an instance is created with a matrix transform refering to the source object. This should allow us to render tree leaves more memory efficient. - Radiosity and to some degree raytracing of such objects is not really efficient still. For radiosity this is fundamentally hard to solve, but raytracing an octree could be created for each object, but the current octree code with it's fixed size doesn't allow this efficiently. - The regression tests survived, but with I expect that some bugs will pop up .. hopefully not too many :). Implementation Notes ==================== - Dupligroups and linked meshes are not rendered as instances yet, since they can in fact be different due to various reasons, instancing of these types of duplis that are the same can be added for them at a later point. - Each ObjectRen now stores it's own database, instead of there being one big databases of faces, verts, .. . Which objects that are actually rendered are defined by the list of ObjectRenInstances, which all refer to an ObjectRen. - Homogeneous coordinatess and clipping is now not stored in vertices anymore, but instead computed on the fly. This couldn't work for instances. That does mean some extra computation has to be done, but memory lookups can be slow too, and this saves some memory. Overall I didn't find a significant speed impact. - OSA rendering for solid and ztransp now is different. Instead of e.g. going 8 times over the databases times and rendering the z-buffer, it now goes over the database once and renders each polygon 8 times. That was necessary to keep instances efficient, and can also give some performance improvement without instances. - There was already instancing support in the yafray export code, now it uses Blender's render instances for export. - UV and color layer storage in the render was a bit messy before, now should be easier to understand. - convertblender.c was reorganized somewhat. Regular render, speedvector and baking now use a single function to create the database, previously there was code duplicated for it. - Some of these changes were done with future multithreading of scene and shadow buffer creation in mind, though especially for scene creation much work remains to be done to make it threadsafe, since it also involves a lot of code from blenkernel, and there is an ugly conflict with the way dupli groups work here .. though in the render code itself it's almost there.

Upgraded max limit for faces in render. Up to now, quads were zbuffered as triangles, with a tag bit to denote which triangle was which part of the quad. That was hardcoded bit 0x800000, which allows a maximum of about 8 million quads... I've made this a nice #define, set to be 16 times larger. So, now the facejunkies can go up to 128 Million faces, were it not that this will eat up a load of memory! I only have 1 Gig in this machine. A test with 9M vertices and 7.5M quads eats up 912 MB of memory already. If this becomes a real issue, I know tricks how to make the vertices 20 bytes smaller, and faces 4 bytes, which would in the above case save about 200 MB. Not much... but probably worth the try? A much better method is of course 'bucketing' the renderdata per tile. It's a spec of the render recode, but not a quicky to add. Also: bug fix in curve code. There was a short counter still, crashing on large curves with resol set to 1024 :)

Three features; - Live scanline updates while rendering Using a timer system, each second now the tiles that are being processed are checked if they could use display. To make this work pretty, I had to use the threaded 'tile processor' for a single thread too, but that's now proven to be stable. Also note that these updates draw per layer, including ztransp progress separately from solid render. - Recode of ztransp OSA Until now (since blender 1.0) the ztransp part was fully rendered and added on top of the solid part with alpha-over. This adding was done before the solid part applied sub-pixel sample filtering, causing the ztransp layer to be always too blurry. Now the ztransp layer uses same sub=pixel filter, resulting in the same AA level (and filter results) as the solid part. Quite noticable with hair renders. - Vector buffer support & preliminary vector-blur Node Using the "Render Layer" panel "Vector" pass button, the motion vectors per pixel are calculated and stored. Accessible via the Compositor. The vector-blur node is horrible btw! It just uses the length of the vector to apply a filter like with current (z)blur. I'm committing it anyway, I'll experiment with it further, and who knows some surprise code shows up!

To make this work pretty, I had to use the threaded 'tile processor' for a single thread too, but that's now proven to be stable. Also note that these updates draw per layer, including ztransp progress separately from solid render. - Recode of ztransp OSA Until now (since blender 1.0) the ztransp part was fully rendered and added on top of the solid part with alpha-over. This adding was done before the solid part applied sub-pixel sample filtering, causing the ztransp layer to be always too blurry. Now the ztransp layer uses same sub=pixel filter, resulting in the same AA level (and filter results) as the solid part. Quite noticable with hair renders. - Vector buffer support & preliminary vector-blur Node Using the "Render Layer" panel "Vector" pass button, the motion vectors per pixel are calculated and stored. Accessible via the Compositor. The vector-blur node is horrible btw! It just uses the length of the vector to apply a filter like with current (z)blur. I'm committing it anyway, I'll experiment with it further, and who knows some surprise code shows up!

Added names to UV and vertex color layers, and display them as a list. Added support for multiple UVs in the render engine. This also involved changing the way faces are stored, to allow data to be added optionally per 256 faces, same as the existing system for vertices. A UV layer can be specified in the Map Input panel and the Geometry node by name. Leaving this field blank will default to the active UV layer. Also added sharing of face selection and hiding between UV layers, and at the same time improved syncing with editmode selection and hiding. Still to do: - Multi UV support for fastshade. - Multires and NMesh preservation of multiple UV sets.

Render Instancing ================= Big commit, but little user visible changes. - Dupliverts and duplifaces are now rendered as instances, instead of storing all of the geometry for each dupli, now an instance is created with a matrix transform refering to the source object. This should allow us to render tree leaves more memory efficient. - Radiosity and to some degree raytracing of such objects is not really efficient still. For radiosity this is fundamentally hard to solve, but raytracing an octree could be created for each object, but the current octree code with it's fixed size doesn't allow this efficiently. - The regression tests survived, but with I expect that some bugs will pop up .. hopefully not too many :). Implementation Notes ==================== - Dupligroups and linked meshes are not rendered as instances yet, since they can in fact be different due to various reasons, instancing of these types of duplis that are the same can be added for them at a later point. - Each ObjectRen now stores it's own database, instead of there being one big databases of faces, verts, .. . Which objects that are actually rendered are defined by the list of ObjectRenInstances, which all refer to an ObjectRen. - Homogeneous coordinatess and clipping is now not stored in vertices anymore, but instead computed on the fly. This couldn't work for instances. That does mean some extra computation has to be done, but memory lookups can be slow too, and this saves some memory. Overall I didn't find a significant speed impact. - OSA rendering for solid and ztransp now is different. Instead of e.g. going 8 times over the databases times and rendering the z-buffer, it now goes over the database once and renders each polygon 8 times. That was necessary to keep instances efficient, and can also give some performance improvement without instances. - There was already instancing support in the yafray export code, now it uses Blender's render instances for export. - UV and color layer storage in the render was a bit messy before, now should be easier to understand. - convertblender.c was reorganized somewhat. Regular render, speedvector and baking now use a single function to create the database, previously there was code duplicated for it. - Some of these changes were done with future multithreading of scene and shadow buffer creation in mind, though especially for scene creation much work remains to be done to make it threadsafe, since it also involves a lot of code from blenkernel, and there is an ugly conflict with the way dupli groups work here .. though in the render code itself it's almost there.

Patch [#29035] Vertex colour baking There is a new option in the Bake panel to enable baking to vertex colors. Unlike regular baking, this mode does not require a UV map or image to bake to, however the object must have a vertex color layer. Thanks to: - AutoCRC for funding - Brech van Lommel and Dalai Felinto for their initial advice on how to implement it - Campbell Barton for helping to make this feature work with modifiers and bmesh

Particles ========= - Fix crash in particle transform with the particle system not editable. - Particle child distribution and caching is now multithreaded. - Child particles now have a separate Render Amount next to the existing Amount. The render amount particles are now only distributed and cached at render time, which should make editing with child particles faster. - Two new options for diffuse strand shading: - Surface Diffuse: computes the strand normal taking the normal at the surface into account. - Blending Distance: the distance in Blender units over which to blend in the normal at the surface. - Special strand rendering for more memory efficient and faster hair and grass. This is a work in progress, and has a number of known issues, don't report bugs to me for this feature yet. More info: http://www.blender.org/development/current-projects/changes-since-244/particles/

Support multiple tangents for BI render & viewport Normal Map node support for GLSL mode and the internal render (multiple tangents support). The Normal Map node is a useful node which is present in the Cycles render. It makes it possible to use normal mapping without additional material node in a node tree. This patch implements Normal Map node for GLSL mode and the internal render. Previously only the active UV layer was used to calculate tangents.

Strand Render Simplification ============================ - Strand render now has options to remove child strands as the object's faces becomes smaller, in the Simplification particle panel. - "Reference Size" is the approximate size of the object on screen, after which simplification starts. - "Rate" is how fast strands are removed. - "Transition" is the percentage of strands being faded out as they are removed. - Another "Viewport" option removes strands on faces that are outside of the viewport. "Rate" again controls how fast these are removed. - Strand render in Blender Units now has an adjustable minimum width. Below this minimum width, strands start fading out instead of getting smaller.

Approximate Ambient Occlusion ============================= A new approximate ambient occlusion method has been added, next to the existing one based on raytracing. This method is specifically targetted at use in animations, since it is inherently noise free, and so will not flicker across frames. http://www.blender.org/development/current-projects/changes-since-244/approximate-ambient-occlusion/ http://peach.blender.org/index.php/approximate-ambient-occlusion/ Further improvements are still needed, but it can be tested already. There are still a number of known issues: - Bias errors on backfaces. - For performance, instanced object do not occlude currently. - Sky textures don't work well, the derivatives for texture evaluation are not correct. - Multiple passes do not work entirely correct (they are not accurate to begin with, but could be better).

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!

This couldn't work for instances. That does mean some extra computation has to be done, but memory lookups can be slow too, and this saves some memory. Overall I didn't find a significant speed impact. - OSA rendering for solid and ztransp now is different. Instead of e.g. going 8 times over the databases times and rendering the z-buffer, it now goes over the database once and renders each polygon 8 times. That was necessary to keep instances efficient, and can also give some performance improvement without instances. - There was already instancing support in the yafray export code, now it uses Blender's render instances for export. - UV and color layer storage in the render was a bit messy before, now should be easier to understand. - convertblender.c was reorganized somewhat. Regular render, speedvector and baking now use a single function to create the database, previously there was code duplicated for it. - Some of these changes were done with future multithreading of scene and shadow buffer creation in mind, though especially for scene creation much work remains to be done to make it threadsafe, since it also involves a lot of code from blenkernel, and there is an ugly conflict with the way dupli groups work here .. though in the render code itself it's almost there.

Render Instancing ================= Big commit, but little user visible changes. - Dupliverts and duplifaces are now rendered as instances, instead of storing all of the geometry for each dupli, now an instance is created with a matrix transform refering to the source object. This should allow us to render tree leaves more memory efficient. - Radiosity and to some degree raytracing of such objects is not really efficient still. For radiosity this is fundamentally hard to solve, but raytracing an octree could be created for each object, but the current octree code with it's fixed size doesn't allow this efficiently. - The regression tests survived, but with I expect that some bugs will pop up .. hopefully not too many :).

Strand Render Simplification ============================ - Strand render now has options to remove child strands as the object's faces becomes smaller, in the Simplification particle panel. - "Reference Size" is the approximate size of the object on screen, after which simplification starts. - "Rate" is how fast strands are removed. - "Transition" is the percentage of strands being faded out as they are removed. - Another "Viewport" option removes strands on faces that are outside of the viewport. "Rate" again controls how fast these are removed. - Strand render in Blender Units now has an adjustable minimum width. Below this minimum width, strands start fading out instead of getting smaller.

Approximate Ambient Occlusion ============================= A new approximate ambient occlusion method has been added, next to the existing one based on raytracing. This method is specifically targetted at use in animations, since it is inherently noise free, and so will not flicker across frames. http://www.blender.org/development/current-projects/changes-since-244/approximate-ambient-occlusion/ http://peach.blender.org/index.php/approximate-ambient-occlusion/ Further improvements are still needed, but it can be tested already. There are still a number of known issues: - Bias errors on backfaces. - For performance, instanced object do not occlude currently. - Sky textures don't work well, the derivatives for texture evaluation are not correct. - Multiple passes do not work entirely correct (they are not accurate to begin with, but could be better).

3D Viewport rendering (Blender Internal) Added incremental re-render on view changes. That means all data preprocessing only needs to be done once on view changes, quite faster that way. Also fixed a bug in raytracing strands with soft shadows, was wrongly changing coordinates in a static array. Note: proper signals for re-renders is still on the todo. Many button options don't signal a re-render yet. Work around: press G+ESC for quick full renders.

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!

Three features; - Live scanline updates while rendering Using a timer system, each second now the tiles that are being processed are checked if they could use display. To make this work pretty, I had to use the threaded 'tile processor' for a single thread too, but that's now proven to be stable. Also note that these updates draw per layer, including ztransp progress separately from solid render. - Recode of ztransp OSA Until now (since blender 1.0) the ztransp part was fully rendered and added on top of the solid part with alpha-over. This adding was done before the solid part applied sub-pixel sample filtering, causing the ztransp layer to be always too blurry. Now the ztransp layer uses same sub=pixel filter, resulting in the same AA level (and filter results) as the solid part. Quite noticable with hair renders. - Vector buffer support & preliminary vector-blur Node Using the "Render Layer" panel "Vector" pass button, the motion vectors per pixel are calculated and stored. Accessible via the Compositor. The vector-blur node is horrible btw! It just uses the length of the vector to apply a filter like with current (z)blur. I'm committing it anyway, I'll experiment with it further, and who knows some surprise code shows up!

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!

Fix T39735: New auto smooth creates artifacts with flat shaded faces(BI) This actually had nothing specific to new split normals, it was an internal limitation of BI raytracer, which would check against neighbor face shadowing only when they shared a common vertex, now it also performs checks when both faces have a vertex with a common "ancestor" (org index). Note this allows to also fix same issue when using SplitEdges modifier (and potentially others?), but only when AutoSmooth is enabled (due to some compute/mem overhead, we do not want to enable this code systematically). Thanks to Brecht for advices and review!

unify include guard defines, __$FILENAME__ without the underscores these clogged up the namespace for autocompleation which was annoying.
