Phew, a lot of work, and no new features... Main target was to make the inner rendering loop using no globals anymore. This is essential for proper usage while raytracing, it caused a lot of hacks in the raycode as well, which even didn't work correctly for all situations (textures especially). Done this by creating a new local struct RenderInput, which replaces usage of the global struct Render R. The latter now only is used to denote image size, viewmatrix, and the like. Making the inner render loops using no globals caused 1000s of vars to be changed... but the result definitely is much nicer code, which enables making 'real' shaders in a next stage. It also enabled me to remove the hacks from ray.c Then i went to the task of removing redundant code. Especially the calculus of texture coords took place (identical) in three locations. Most obvious is the change in the unified render part, which is much less code now; it uses the same rendering routines as normal render now. (Note; not for halos yet!) I also removed 6 files called 'shadowbuffer' something. This was experimen- tal stuff from NaN days. And again saved a lot of double used code. Finally I went over the blenkernel and blender/src calls to render stuff. Here the same local data is used now, resulting in less dependency. I also moved render-texture to the render module, this was still in Kernel. (new file: texture.c) So! After this commit I will check on the autofiles, to try to fix that. MSVC people have to do it themselves. This commit will need quite some testing help, but I'm around!

Result of 2 weeks of quiet coding work in Greece :) Aim was to get a total refresh of the animation system. This is needed because; - we need to upgrade it with 21st century features - current code is spaghetti/hack combo, and hides good design - it should become lag-free with using dependency graphs A full log, with complete code API/structure/design explanation will follow, that's a load of work... so here below the list with hot changes; - The entire object update system (matrices, geometry) is now centralized. Calls to where_is_object and makeDispList are forbidden, instead we tag objects 'changed' and let the depgraph code sort it out - Removed all old "Ika" code - Depgraph is aware of all relationships, including meta balls, constraints, bevelcurve, and so on. - Made depgraph aware of relation types and layers, to do smart flushing of 'changed' events. Nothing gets calculated too often! - Transform uses depgraph to detect changes - On frame-advance, depgraph flushes animated changes Armatures; Almost all armature related code has been fully built from scratch. It now reveils the original design much better, with a very clean implementation, lag free without even calculating each Bone more than once. Result is quite a speedup yes! Important to note is; 1) Armature is data containing the 'rest position' 2) Pose is the changes of rest position, and always on object level. That way more Objects can use same Pose. Also constraints are in Pose 3) Actions only contain the Ipos to change values in Poses. - Bones draw unrotated now - Drawing bones speedup enormously (10-20 times) - Bone selecting in EditMode, selection state is saved for PoseMode, and vice-versa - Undo in editmode - Bone renaming does vertexgroups, constraints, posechannels, actions, for all users of Armature in entire file - Added Bone renaming in NKey panel - Nkey PoseMode shows eulers now - EditMode and PoseMode now have 'active' bone too (last clicked) - Parenting in EditMode' CTRL+P, ALT+P, with nice options! - Pose is added in Outliner now, with showing that constraints are in the Pose, not Armature - Disconnected IK solving from constraints. It's a separate phase now, on top of the full Pose calculations - Pose itself has a dependency graph too, so evaluation order is lag free. TODO NOW; - Rotating in Posemode has incorrect inverse transform (Martin will fix) - Python Bone/Armature/Pose API disabled... needs full recode too (wait for my doc!) - Game engine will need upgrade too - Depgraph code needs revision, cleanup, can be much faster! (But, compliments for Jean-Luc, it works like a charm!) - IK changed, it now doesnt use previous position to advance to next position anymore. That system looks nice (no flips) but is not well suited for NLA and background render. TODO LATER; We now can do loadsa new nifty features as well; like: - Kill PoseMode (can be option for armatures itself) - Make B-Bones (Bezier, Bspline, like for spines) - Move all silly button level edit to 3d window (like CTRL+I = add IK) - Much better & informative drawing - Fix action/nla editors - Put all ipos in Actions (object, mesh key, lamp color) - Add hooks - Null bones - Much more advanced constraints... Bugfixes; - OGL render (view3d header) had wrong first frame on anim render - Ipo 'recording' mode had wrong playback speed - Vertex-key mode now sticks to show 'active key', until frame change -Ton-

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes. Render engine is an owner of this context. This context is passed to all object update routines.

Color Management, Stage 2: Switch color pipeline to use OpenColorIO Replace old color pipeline which was supporting linear/sRGB color spaces only with OpenColorIO-based pipeline. This introduces two configurable color spaces: - Input color space for images and movie clips. This space is used to convert images/movies from color space in which file is saved to Blender's linear space (for float images, byte images are not internally converted, only input space is stored for such images and used later). This setting could be found in image/clip data block settings. - Display color space which defines space in which particular display is working. This settings could be found in scene's Color Management panel. When render result is being displayed on the screen, apart from converting image to display space, some additional conversions could happen. This conversions are: - View, which defines tone curve applying before display transformation. These are different ways to view the image on the same display device. For example it could be used to emulate film view on sRGB display. - Exposure affects on image exposure before tone map is applied. - Gamma is post-display gamma correction, could be used to match particular display gamma. - RGB curves are user-defined curves which are applying before display transformation, could be used for different purposes. All this settings by default are only applying on render result and does not affect on other images. If some particular image needs to be affected by this transformation, "View as Render" setting of image data block should be set to truth. Movie clips are always affected by all display transformations. This commit also introduces configurable color space in which sequencer is working. This setting could be found in scene's Color Management panel and it should be used if such stuff as grading needs to be done in color space different from sRGB (i.e. when Film view on sRGB display is use, using VD16 space as sequencer's internal space would make grading working in space which is close to the space using for display). Some technical notes: - Image buffer's float buffer is now always in linear space, even if it was created from 16bit byte images. - Space of byte buffer is stored in image buffer's rect_colorspace property. - Profile of image buffer was removed since it's not longer meaningful. - OpenGL and GLSL is supposed to always work in sRGB space. It is possible to support other spaces, but it's quite large project which isn't so much important. - Legacy Color Management option disabled is emulated by using None display. It could have some regressions, but there's no clear way to avoid them. - If OpenColorIO is disabled on build time, it should make blender behaving in the same way as previous release with color management enabled. More details could be found at this page (more details would be added soon): http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.64/Color_Management -- Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO integration and to Brecht van Lommel for some further development and code/ usecase review!

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!

Important to note is; 1) Armature is data containing the 'rest position' 2) Pose is the changes of rest position, and always on object level. That way more Objects can use same Pose. Also constraints are in Pose 3) Actions only contain the Ipos to change values in Poses. - Bones draw unrotated now - Drawing bones speedup enormously (10-20 times) - Bone selecting in EditMode, selection state is saved for PoseMode, and vice-versa - Undo in editmode - Bone renaming does vertexgroups, constraints, posechannels, actions, for all users of Armature in entire file - Added Bone renaming in NKey panel - Nkey PoseMode shows eulers now - EditMode and PoseMode now have 'active' bone too (last clicked) - Parenting in EditMode' CTRL+P, ALT+P, with nice options! - Pose is added in Outliner now, with showing that constraints are in the Pose, not Armature - Disconnected IK solving from constraints. It's a separate phase now, on top of the full Pose calculations - Pose itself has a dependency graph too, so evaluation order is lag free. TODO NOW; - Rotating in Posemode has incorrect inverse transform (Martin will fix) - Python Bone/Armature/Pose API disabled... needs full recode too (wait for my doc!) - Game engine will need upgrade too - Depgraph code needs revision, cleanup, can be much faster! (But, compliments for Jean-Luc, it works like a charm!) - IK changed, it now doesnt use previous position to advance to next position anymore. That system looks nice (no flips) but is not well suited for NLA and background render. TODO LATER; We now can do loadsa new nifty features as well; like: - Kill PoseMode (can be option for armatures itself) - Make B-Bones (Bezier, Bspline, like for spines) - Move all silly button level edit to 3d window (like CTRL+I = add IK) - Much better & informative drawing - Fix action/nla editors - Put all ipos in Actions (object, mesh key, lamp color) - Add hooks - Null bones - Much more advanced constraints... Bugfixes; - OGL render (view3d header) had wrong first frame on anim render - Ipo 'recording' mode had wrong playback speed - Vertex-key mode now sticks to show 'active key', until frame change -Ton-

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes. Render engine is an owner of this context. This context is passed to all object update routines.

Color Management, Stage 2: Switch color pipeline to use OpenColorIO Replace old color pipeline which was supporting linear/sRGB color spaces only with OpenColorIO-based pipeline. This introduces two configurable color spaces: - Input color space for images and movie clips. This space is used to convert images/movies from color space in which file is saved to Blender's linear space (for float images, byte images are not internally converted, only input space is stored for such images and used later). This setting could be found in image/clip data block settings. - Display color space which defines space in which particular display is working. This settings could be found in scene's Color Management panel. When render result is being displayed on the screen, apart from converting image to display space, some additional conversions could happen. This conversions are: - View, which defines tone curve applying before display transformation. These are different ways to view the image on the same display device. For example it could be used to emulate film view on sRGB display. - Exposure affects on image exposure before tone map is applied. - Gamma is post-display gamma correction, could be used to match particular display gamma. - RGB curves are user-defined curves which are applying before display transformation, could be used for different purposes. All this settings by default are only applying on render result and does not affect on other images. If some particular image needs to be affected by this transformation, "View as Render" setting of image data block should be set to truth. Movie clips are always affected by all display transformations. This commit also introduces configurable color space in which sequencer is working. This setting could be found in scene's Color Management panel and it should be used if such stuff as grading needs to be done in color space different from sRGB (i.e. when Film view on sRGB display is use, using VD16 space as sequencer's internal space would make grading working in space which is close to the space using for display). Some technical notes: - Image buffer's float buffer is now always in linear space, even if it was created from 16bit byte images. - Space of byte buffer is stored in image buffer's rect_colorspace property. - Profile of image buffer was removed since it's not longer meaningful. - OpenGL and GLSL is supposed to always work in sRGB space. It is possible to support other spaces, but it's quite large project which isn't so much important. - Legacy Color Management option disabled is emulated by using None display. It could have some regressions, but there's no clear way to avoid them. - If OpenColorIO is disabled on build time, it should make blender behaving in the same way as previous release with color management enabled. More details could be found at this page (more details would be added soon): http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.64/Color_Management -- Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO integration and to Brecht van Lommel for some further development and code/ usecase review!

Added the new Timeline Window, copied from Tuhopuu, coded by Matt Ebb. Main change is that it's an own Space type now, not part of the Audio window... the audio window should restrict to own options. This way functionality is nicely separated. Since it's the first time I added a new space (since long!) I've made an extensive tutorial as well. You can find that here: http://www.blender3d.org/cms/Adding_new_Space_Window.557.0.html Notes for using timewindow; - Add time markers with MKey - CTRL+M gives option to name Marker - Markers cannot be moved yet... - Pageup-Pagedown keys moves current frame to next-prev Marker - Xkey removes Markers - If an object has Ipos or an Action, it draws key lines - CTRL+Pageup-Pagedown moves current frame to next-prev Key - Press S or E to set start/end frame for playback Notes about the implementation in Tuhopuu: - Add new Marker now selects new, deselects others - Selecting Marker didn't work like elsewhere in Blender, on click it should deselect all, except the indicated Marker. Not when holding SHIFT of course - Not exported functions are static now - Removed unused defines (MARKER_NONE NEXT_AVAIL) - Drawing order was confusing, doing too many matrix calls - Removed not needed scrollbar, added new function to draw time values. (Has advantage the MMB scroll works not confusing on a scrollbar) - Added proper support for 'frame mapping' - The string button (name Marker) had a bug (checked str[64] while str was only 64 long) - String button itself didn't allow "OK on enter" - Made frame buttons in header larger, the arrows overlapped - Removed support for negative frame values, that won't work so simple!

=== Custom Transform Orientation === Custom Orientations can be added with Ctrl-Shift-C (hotkey suggestions are welcomed), this adds and select the new alignment. Custom Orientations can also be added, deleted, selected from the Transform Orientations panel (View -> Transform Orientations). Standard orientations (global, local, normal, view) can also be selected from this panel. If you plan on using only a single custom orientation and don't really need a list, I suggest you use the hotkey as it adds and selects at the same time. Custom Orientations are save in the scene and are selected per 3D view (like normal orientation). Adding from an object, the orientation is a normalized version of the object's orientation. Adding from mesh data, a single element (vertex, edge, face) must be selected in its respective selection mode. Vertex orientation Z-axis is based on the normal, edge Z-axis on the edge itself (X-axis is on the XoY plane when possible, Y-axis is perpendicular to the rest). Face orientation Z-axis is the face normal, X-axis is perpendicular to the first edge, Y-axis is perpendicular to the rest. (More logical orientations can be suggested). I plan to add: 2 vertice (connected or not) => edge orientation , 3 vertice = face orientation Differences from the patch: - orientations no longer link back to the object they came from, everything is copy on creation. - orientations are overwritten based on name (if you add an orientation with the same name as one that already exists, it overwrites the old one)

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!

Color Management, Stage 2: Switch color pipeline to use OpenColorIO Replace old color pipeline which was supporting linear/sRGB color spaces only with OpenColorIO-based pipeline. This introduces two configurable color spaces: - Input color space for images and movie clips. This space is used to convert images/movies from color space in which file is saved to Blender's linear space (for float images, byte images are not internally converted, only input space is stored for such images and used later). This setting could be found in image/clip data block settings. - Display color space which defines space in which particular display is working. This settings could be found in scene's Color Management panel. When render result is being displayed on the screen, apart from converting image to display space, some additional conversions could happen. This conversions are: - View, which defines tone curve applying before display transformation. These are different ways to view the image on the same display device. For example it could be used to emulate film view on sRGB display. - Exposure affects on image exposure before tone map is applied. - Gamma is post-display gamma correction, could be used to match particular display gamma. - RGB curves are user-defined curves which are applying before display transformation, could be used for different purposes. All this settings by default are only applying on render result and does not affect on other images. If some particular image needs to be affected by this transformation, "View as Render" setting of image data block should be set to truth. Movie clips are always affected by all display transformations. This commit also introduces configurable color space in which sequencer is working. This setting could be found in scene's Color Management panel and it should be used if such stuff as grading needs to be done in color space different from sRGB (i.e. when Film view on sRGB display is use, using VD16 space as sequencer's internal space would make grading working in space which is close to the space using for display). Some technical notes: - Image buffer's float buffer is now always in linear space, even if it was created from 16bit byte images. - Space of byte buffer is stored in image buffer's rect_colorspace property. - Profile of image buffer was removed since it's not longer meaningful. - OpenGL and GLSL is supposed to always work in sRGB space. It is possible to support other spaces, but it's quite large project which isn't so much important. - Legacy Color Management option disabled is emulated by using None display. It could have some regressions, but there's no clear way to avoid them. - If OpenColorIO is disabled on build time, it should make blender behaving in the same way as previous release with color management enabled. More details could be found at this page (more details would be added soon): http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.64/Color_Management -- Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO integration and to Brecht van Lommel for some further development and code/ usecase review!

Raytrace modifications from the Render Branch. These should not have any effect on render results, except in some cases with you have overlapping faces, where the noise seems to be slightly reduced. There are some performance improvements, for simple scenes I wouldn't expect more than 5-10% to be cut off the render time, for sintel scenes we got about 50% on average, that's with millions of polygons on intel quad cores. This because memory access / cache misses were the main bottleneck for those scenes, and the optimizations improve that. Interal changes: * Remove RE_raytrace.h, raytracer is now only used by render engine again. * Split non-public parts rayobject.h into rayobject_internal.h, hopefully makes it clearer how the API is used. * Added rayintersection.h to contain some of the stuff from RE_raytrace.h * Change Isect.vec/labda to Isect.dir/dist, previously vec was sometimes normalized and sometimes not, confusing... now dir is always normalized and dist contains the distance. * Change VECCOPY and similar to BLI_math functions. * Force inlining of auxiliary functions for ray-triangle/quad intersection, helps a few percentages. * Reorganize svbvh code so all the traversal functions are in one file * Don't do test for root so that push_childs can be inlined * Make shadow a template parameter so it doesn't need to be runtime checked * Optimization in raytree building, was computing bounding boxes more often than necessary. * Leave out logf() factor in SAH, makes tree build quicker with no noticeable influence on raytracing on performance? * Set max childs to 4, simplifies traversal code a bit, but also seems to help slightly in general. * Store child pointers and child bb just as fixed arrays of size 4 in nodes, nearly all nodes have this many children, so overall it actually reduces memory usage a bit and avoids a pointer indirection.

Unified effector functionality for particles, cloth and softbody * Unified scene wide gravity (currently in scene buttons) instead of each simulation having it's own gravity. * Weight parameters for all effectors and an effector group setting. * Every effector can use noise. * Most effectors have "shapes" point, plane, surface, every point. - "Point" is most like the old effectors and uses the effector location as the effector point. - "Plane" uses the closest point on effectors local xy-plane as the effector point. - "Surface" uses the closest point on an effector object's surface as the effector point. - "Every Point" uses every point in a mesh effector object as an effector point. - The falloff is calculated from this point, so for example with "surface" shape and "use only negative z axis" it's possible to apply force only "inside" the effector object. * Spherical effector is now renamed as "force" as it's no longer just spherical. * New effector parameter "flow", which makes the effector act as surrounding air velocity, so the resulting force is proportional to the velocity difference of the point and "air velocity". For example a wind field with flow=1.0 results in proper non-accelerating wind. * New effector fields "turbulence", which creates nice random flow paths, and "drag", which slows the points down. * Much improved vortex field. * Effectors can now effect particle rotation as well as location. * Use full, or only positive/negative z-axis to apply force (note. the z-axis is the surface normal in the case of effector shape "surface") * New "force field" submenu in add menu, which adds an empty with the chosen effector (curve object for corve guides). * Other dynamics should be quite easy to add to the effector system too if wanted. * "Unified" doesn't mean that force fields give the exact same results for particles, softbody & cloth, since their final effect depends on many external factors, like for example the surface area of the effected faces. Code changes * Subversion bump for correct handling of global gravity. * Separate ui py file for common dynamics stuff. * Particle settings updating is flushed with it's id through DAG_id_flush_update(..). Known issues * Curve guides don't yet have all ui buttons in place, but they should work none the less. * Hair dynamics don't yet respect force fields. Other changes * Particle emission defaults now to frames 1-200 with life of 50 frames to fill the whole default timeline. * Many particles drawing related crashes fixed. * Sometimes particles didn't update on first frame properly. * Hair with object/group visualization didn't work properly. * Memory leaks with PointCacheID lists (Genscher, remember to free pidlists after use :).

Color Management, Stage 2: Switch color pipeline to use OpenColorIO Replace old color pipeline which was supporting linear/sRGB color spaces only with OpenColorIO-based pipeline. This introduces two configurable color spaces: - Input color space for images and movie clips. This space is used to convert images/movies from color space in which file is saved to Blender's linear space (for float images, byte images are not internally converted, only input space is stored for such images and used later). This setting could be found in image/clip data block settings. - Display color space which defines space in which particular display is working. This settings could be found in scene's Color Management panel. When render result is being displayed on the screen, apart from converting image to display space, some additional conversions could happen. This conversions are: - View, which defines tone curve applying before display transformation. These are different ways to view the image on the same display device. For example it could be used to emulate film view on sRGB display. - Exposure affects on image exposure before tone map is applied. - Gamma is post-display gamma correction, could be used to match particular display gamma. - RGB curves are user-defined curves which are applying before display transformation, could be used for different purposes. All this settings by default are only applying on render result and does not affect on other images. If some particular image needs to be affected by this transformation, "View as Render" setting of image data block should be set to truth. Movie clips are always affected by all display transformations. This commit also introduces configurable color space in which sequencer is working. This setting could be found in scene's Color Management panel and it should be used if such stuff as grading needs to be done in color space different from sRGB (i.e. when Film view on sRGB display is use, using VD16 space as sequencer's internal space would make grading working in space which is close to the space using for display). Some technical notes: - Image buffer's float buffer is now always in linear space, even if it was created from 16bit byte images. - Space of byte buffer is stored in image buffer's rect_colorspace property. - Profile of image buffer was removed since it's not longer meaningful. - OpenGL and GLSL is supposed to always work in sRGB space. It is possible to support other spaces, but it's quite large project which isn't so much important. - Legacy Color Management option disabled is emulated by using None display. It could have some regressions, but there's no clear way to avoid them. - If OpenColorIO is disabled on build time, it should make blender behaving in the same way as previous release with color management enabled. More details could be found at this page (more details would be added soon): http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.64/Color_Management -- Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO integration and to Brecht van Lommel for some further development and code/ usecase review!

/* group patch... */
Result of 2 weeks of quiet coding work in Greece :) Aim was to get a total refresh of the animation system. This is needed because; - we need to upgrade it with 21st century features - current code is spaghetti/hack combo, and hides good design - it should become lag-free with using dependency graphs A full log, with complete code API/structure/design explanation will follow, that's a load of work... so here below the list with hot changes; - The entire object update system (matrices, geometry) is now centralized. Calls to where_is_object and makeDispList are forbidden, instead we tag objects 'changed' and let the depgraph code sort it out - Removed all old "Ika" code - Depgraph is aware of all relationships, including meta balls, constraints, bevelcurve, and so on. - Made depgraph aware of relation types and layers, to do smart flushing of 'changed' events. Nothing gets calculated too often! - Transform uses depgraph to detect changes - On frame-advance, depgraph flushes animated changes Armatures; Almost all armature related code has been fully built from scratch. It now reveils the original design much better, with a very clean implementation, lag free without even calculating each Bone more than once. Result is quite a speedup yes! Important to note is; 1) Armature is data containing the 'rest position' 2) Pose is the changes of rest position, and always on object level. That way more Objects can use same Pose. Also constraints are in Pose 3) Actions only contain the Ipos to change values in Poses. - Bones draw unrotated now - Drawing bones speedup enormously (10-20 times) - Bone selecting in EditMode, selection state is saved for PoseMode, and vice-versa - Undo in editmode - Bone renaming does vertexgroups, constraints, posechannels, actions, for all users of Armature in entire file - Added Bone renaming in NKey panel - Nkey PoseMode shows eulers now - EditMode and PoseMode now have 'active' bone too (last clicked) - Parenting in EditMode' CTRL+P, ALT+P, with nice options! - Pose is added in Outliner now, with showing that constraints are in the Pose, not Armature - Disconnected IK solving from constraints. It's a separate phase now, on top of the full Pose calculations - Pose itself has a dependency graph too, so evaluation order is lag free. TODO NOW; - Rotating in Posemode has incorrect inverse transform (Martin will fix) - Python Bone/Armature/Pose API disabled... needs full recode too (wait for my doc!) - Game engine will need upgrade too - Depgraph code needs revision, cleanup, can be much faster! (But, compliments for Jean-Luc, it works like a charm!) - IK changed, it now doesnt use previous position to advance to next position anymore. That system looks nice (no flips) but is not well suited for NLA and background render. TODO LATER; We now can do loadsa new nifty features as well; like: - Kill PoseMode (can be option for armatures itself) - Make B-Bones (Bezier, Bspline, like for spines) - Move all silly button level edit to 3d window (like CTRL+I = add IK) - Much better & informative drawing - Fix action/nla editors - Put all ipos in Actions (object, mesh key, lamp color) - Add hooks - Null bones - Much more advanced constraints... Bugfixes; - OGL render (view3d header) had wrong first frame on anim render - Ipo 'recording' mode had wrong playback speed - Vertex-key mode now sticks to show 'active key', until frame change -Ton-

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes. Render engine is an owner of this context. This context is passed to all object update routines.

Big commit with work on Groups & Libraries: -> Any Group Duplicate now can get local timing and local NLA override. This enables to control the entire animation system of the Group. Two methods for this have been implemented. 1) The quick way: just give the duplicator a "Startframe" offset. 2) Advanced: in the NLA Editor you can add ActionStrips to the duplicator to override NLA/action of any Grouped Object. For "Group NLA" to work, an ActionStrip needs to know which Object in a group it controls. On adding a strip, the code checks if an Action was already used by an Object in the Group, and assigns it automatic to that Object. You can also set this in the Nkey "Properties" panel for the strip. Change in NLA: the SHIFT+A "Add strip" command now always adds strips to the active Object. (It used to check where mouse was). This allows to add NLA strips to Objects that didn't have actions/nla yet. Important note: In Blender, duplicates are fully procedural and generated on the fly for each redraw. This means that redraw speed equals to stepping through frames, when using animated Duplicated Groups. -> Recoded entire duplicator system The old method was antique and clumsy, using globals and full temporal copies of Object. The new system is nicer in control, faster, and since it doesn't use temporal object copies anymore, it works better with Derived Mesh and DisplayList and rendering. By centralizing the code for duplicating, more options can be easier added. Features to note: - Duplicates now draw selected/unselected based on its Duplicator setting. - Same goes for the drawtype (wire, solid, selection outline, etc) - Duplicated Groups can be normally selected too Bonus goodie: SHIFT+A (Toolbox) now has entry "Add group" too, with a listing of all groups, allowing to add Group instances immediate. -> Library System - SHIFT+F4 data browse now shows the entire path for linked data - Outliner draws Library Icons to denote linked data - Outliner operation added: "Make Local" for library data. - Outliner now also draws Groups in regular view, allowing to unlink too. -> Fixes - depsgraph missed signal update for bone-parented Objects - on reading file, the entire database was tagged to "recalc" fully, causing unnecessary slowdown on reading. Might have missed stuff... :)

The new system is nicer in control, faster, and since it doesn't use temporal object copies anymore, it works better with Derived Mesh and DisplayList and rendering. By centralizing the code for duplicating, more options can be easier added. Features to note: - Duplicates now draw selected/unselected based on its Duplicator setting. - Same goes for the drawtype (wire, solid, selection outline, etc) - Duplicated Groups can be normally selected too Bonus goodie: SHIFT+A (Toolbox) now has entry "Add group" too, with a listing of all groups, allowing to add Group instances immediate. -> Library System - SHIFT+F4 data browse now shows the entire path for linked data - Outliner draws Library Icons to denote linked data - Outliner operation added: "Make Local" for library data. - Outliner now also draws Groups in regular view, allowing to unlink too. -> Fixes - depsgraph missed signal update for bone-parented Objects - on reading file, the entire database was tagged to "recalc" fully, causing unnecessary slowdown on reading. Might have missed stuff... :)

Big commit with work on Groups & Libraries: -> Any Group Duplicate now can get local timing and local NLA override. This enables to control the entire animation system of the Group. Two methods for this have been implemented. 1) The quick way: just give the duplicator a "Startframe" offset. 2) Advanced: in the NLA Editor you can add ActionStrips to the duplicator to override NLA/action of any Grouped Object. For "Group NLA" to work, an ActionStrip needs to know which Object in a group it controls. On adding a strip, the code checks if an Action was already used by an Object in the Group, and assigns it automatic to that Object. You can also set this in the Nkey "Properties" panel for the strip. Change in NLA: the SHIFT+A "Add strip" command now always adds strips to the active Object. (It used to check where mouse was). This allows to add NLA strips to Objects that didn't have actions/nla yet. Important note: In Blender, duplicates are fully procedural and generated on the fly for each redraw.

Result of 2 weeks of quiet coding work in Greece :) Aim was to get a total refresh of the animation system. This is needed because; - we need to upgrade it with 21st century features - current code is spaghetti/hack combo, and hides good design - it should become lag-free with using dependency graphs A full log, with complete code API/structure/design explanation will follow, that's a load of work... so here below the list with hot changes; - The entire object update system (matrices, geometry) is now centralized. Calls to where_is_object and makeDispList are forbidden, instead we tag objects 'changed' and let the depgraph code sort it out - Removed all old "Ika" code - Depgraph is aware of all relationships, including meta balls, constraints, bevelcurve, and so on. - Made depgraph aware of relation types and layers, to do smart flushing of 'changed' events. Nothing gets calculated too often! - Transform uses depgraph to detect changes - On frame-advance, depgraph flushes animated changes Armatures; Almost all armature related code has been fully built from scratch. It now reveils the original design much better, with a very clean implementation, lag free without even calculating each Bone more than once. Result is quite a speedup yes! Important to note is; 1) Armature is data containing the 'rest position' 2) Pose is the changes of rest position, and always on object level. That way more Objects can use same Pose. Also constraints are in Pose 3) Actions only contain the Ipos to change values in Poses. - Bones draw unrotated now - Drawing bones speedup enormously (10-20 times) - Bone selecting in EditMode, selection state is saved for PoseMode, and vice-versa - Undo in editmode - Bone renaming does vertexgroups, constraints, posechannels, actions, for all users of Armature in entire file - Added Bone renaming in NKey panel - Nkey PoseMode shows eulers now - EditMode and PoseMode now have 'active' bone too (last clicked) - Parenting in EditMode' CTRL+P, ALT+P, with nice options! - Pose is added in Outliner now, with showing that constraints are in the Pose, not Armature - Disconnected IK solving from constraints. It's a separate phase now, on top of the full Pose calculations - Pose itself has a dependency graph too, so evaluation order is lag free. TODO NOW; - Rotating in Posemode has incorrect inverse transform (Martin will fix) - Python Bone/Armature/Pose API disabled... needs full recode too (wait for my doc!) - Game engine will need upgrade too - Depgraph code needs revision, cleanup, can be much faster! (But, compliments for Jean-Luc, it works like a charm!) - IK changed, it now doesnt use previous position to advance to next position anymore. That system looks nice (no flips) but is not well suited for NLA and background render. TODO LATER; We now can do loadsa new nifty features as well; like: - Kill PoseMode (can be option for armatures itself) - Make B-Bones (Bezier, Bspline, like for spines) - Move all silly button level edit to 3d window (like CTRL+I = add IK) - Much better & informative drawing - Fix action/nla editors - Put all ipos in Actions (object, mesh key, lamp color) - Add hooks - Null bones - Much more advanced constraints... Bugfixes; - OGL render (view3d header) had wrong first frame on anim render - Ipo 'recording' mode had wrong playback speed - Vertex-key mode now sticks to show 'active key', until frame change -Ton-

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes. Render engine is an owner of this context. This context is passed to all object update routines.

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes. Render engine is an owner of this context. This context is passed to all object update routines.

Result of 2 weeks of quiet coding work in Greece :) Aim was to get a total refresh of the animation system. This is needed because; - we need to upgrade it with 21st century features - current code is spaghetti/hack combo, and hides good design - it should become lag-free with using dependency graphs A full log, with complete code API/structure/design explanation will follow, that's a load of work... so here below the list with hot changes; - The entire object update system (matrices, geometry) is now centralized. Calls to where_is_object and makeDispList are forbidden, instead we tag objects 'changed' and let the depgraph code sort it out - Removed all old "Ika" code - Depgraph is aware of all relationships, including meta balls, constraints, bevelcurve, and so on. - Made depgraph aware of relation types and layers, to do smart flushing of 'changed' events. Nothing gets calculated too often! - Transform uses depgraph to detect changes - On frame-advance, depgraph flushes animated changes Armatures; Almost all armature related code has been fully built from scratch. It now reveils the original design much better, with a very clean implementation, lag free without even calculating each Bone more than once. Result is quite a speedup yes! Important to note is; 1) Armature is data containing the 'rest position' 2) Pose is the changes of rest position, and always on object level. That way more Objects can use same Pose. Also constraints are in Pose 3) Actions only contain the Ipos to change values in Poses. - Bones draw unrotated now - Drawing bones speedup enormously (10-20 times) - Bone selecting in EditMode, selection state is saved for PoseMode, and vice-versa - Undo in editmode - Bone renaming does vertexgroups, constraints, posechannels, actions, for all users of Armature in entire file - Added Bone renaming in NKey panel - Nkey PoseMode shows eulers now - EditMode and PoseMode now have 'active' bone too (last clicked) - Parenting in EditMode' CTRL+P, ALT+P, with nice options! - Pose is added in Outliner now, with showing that constraints are in the Pose, not Armature - Disconnected IK solving from constraints. It's a separate phase now, on top of the full Pose calculations - Pose itself has a dependency graph too, so evaluation order is lag free. TODO NOW; - Rotating in Posemode has incorrect inverse transform (Martin will fix) - Python Bone/Armature/Pose API disabled... needs full recode too (wait for my doc!) - Game engine will need upgrade too - Depgraph code needs revision, cleanup, can be much faster! (But, compliments for Jean-Luc, it works like a charm!) - IK changed, it now doesnt use previous position to advance to next position anymore. That system looks nice (no flips) but is not well suited for NLA and background render. TODO LATER; We now can do loadsa new nifty features as well; like: - Kill PoseMode (can be option for armatures itself) - Make B-Bones (Bezier, Bspline, like for spines) - Move all silly button level edit to 3d window (like CTRL+I = add IK) - Much better & informative drawing - Fix action/nla editors - Put all ipos in Actions (object, mesh key, lamp color) - Add hooks - Null bones - Much more advanced constraints... Bugfixes; - OGL render (view3d header) had wrong first frame on anim render - Ipo 'recording' mode had wrong playback speed - Vertex-key mode now sticks to show 'active key', until frame change -Ton-

Fix T38054: High CPU usage with many objects This is a regression since threaded dependency graph landed to master. Root of the issue goes to the loads of graph preparation being done even if there's nothing to be updated. The idea of this change is to use ID type recalc bits to determine whether there're objects to be updated. Generally speaking, we now check object and object data datablocks with DAG_id_type_tagged() and if there's no such IDs tagged we skip the whole task pool creation and so, The only difficult aspect was that in some circumstances it was possible that there are tagged objects but nothing in ID recalc bit fields. There were several different circumstances when it was possible: * When one assigns object->recalc flag directly DAG flush didn't set corresponding bits to ID recalc bits. Partially it is fixed by making it so flush will set bitfield, but also for object types there's no reason to assign recalc flag directly. Using generic DAG_id_type_tag works almost the same fast as direct assignment, ensures all the bitflags are set properly and for the long run it seems it's what we would actually want to. * DAG_on_visible_update() didn't set recalc bits at all. * Some areas were checking for object->recalc != 0, however it is was possible that object recalc flag contains PSYS_RECALC_CHILD which was never cleaned from there. No idea why would we need to assign such a flag when enabling scene simplification, this is to be investigated separately. * It is possible that scene_update_post and frame_update_post handlers will modify objects. The issue is that DAG_ids_clear_recalc is called just after callbacks, which leaves objects with recalc flags but no corresponding bit in ID recalc bitfield. This leads to some kind of regression when using ID type tag fields to check whether there objects to be updated internally comparing threaded DAG with legacy one. For now let's have a workaround which will preserve tag for ID_OB if there're objects with OB_RECALC_ALL bits. This keeps behavior unchanged comparing with 2.69 release.

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes.

Fix T38054: High CPU usage with many objects This is a regression since threaded dependency graph landed to master. Root of the issue goes to the loads of graph preparation being done even if there's nothing to be updated. The idea of this change is to use ID type recalc bits to determine whether there're objects to be updated. Generally speaking, we now check object and object data datablocks with DAG_id_type_tagged() and if there's no such IDs tagged we skip the whole task pool creation and so, The only difficult aspect was that in some circumstances it was possible that there are tagged objects but nothing in ID recalc bit fields. There were several different circumstances when it was possible: * When one assigns object->recalc flag directly DAG flush didn't set corresponding bits to ID recalc bits. Partially it is fixed by making it so flush will set bitfield, but also for object types there's no reason to assign recalc flag directly. Using generic DAG_id_type_tag works almost the same fast as direct assignment, ensures all the bitflags are set properly and for the long run it seems it's what we would actually want to. * DAG_on_visible_update() didn't set recalc bits at all. * Some areas were checking for object->recalc != 0, however it is was possible that object recalc flag contains PSYS_RECALC_CHILD which was never cleaned from there. No idea why would we need to assign such a flag when enabling scene simplification, this is to be investigated separately. * It is possible that scene_update_post and frame_update_post handlers will modify objects.

BKE_mask_update_scene(bmain, scene);
Result of 2 weeks of quiet coding work in Greece :) Aim was to get a total refresh of the animation system. This is needed because; - we need to upgrade it with 21st century features - current code is spaghetti/hack combo, and hides good design - it should become lag-free with using dependency graphs A full log, with complete code API/structure/design explanation will follow, that's a load of work... so here below the list with hot changes; - The entire object update system (matrices, geometry) is now centralized. Calls to where_is_object and makeDispList are forbidden, instead we tag objects 'changed' and let the depgraph code sort it out - Removed all old "Ika" code - Depgraph is aware of all relationships, including meta balls, constraints, bevelcurve, and so on. - Made depgraph aware of relation types and layers, to do smart flushing of 'changed' events. Nothing gets calculated too often! - Transform uses depgraph to detect changes - On frame-advance, depgraph flushes animated changes Armatures; Almost all armature related code has been fully built from scratch. It now reveils the original design much better, with a very clean implementation, lag free without even calculating each Bone more than once. Result is quite a speedup yes! Important to note is; 1) Armature is data containing the 'rest position' 2) Pose is the changes of rest position, and always on object level. That way more Objects can use same Pose. Also constraints are in Pose 3) Actions only contain the Ipos to change values in Poses. - Bones draw unrotated now - Drawing bones speedup enormously (10-20 times) - Bone selecting in EditMode, selection state is saved for PoseMode, and vice-versa - Undo in editmode - Bone renaming does vertexgroups, constraints, posechannels, actions, for all users of Armature in entire file - Added Bone renaming in NKey panel - Nkey PoseMode shows eulers now - EditMode and PoseMode now have 'active' bone too (last clicked) - Parenting in EditMode' CTRL+P, ALT+P, with nice options! - Pose is added in Outliner now, with showing that constraints are in the Pose, not Armature - Disconnected IK solving from constraints. It's a separate phase now, on top of the full Pose calculations - Pose itself has a dependency graph too, so evaluation order is lag free. TODO NOW; - Rotating in Posemode has incorrect inverse transform (Martin will fix) - Python Bone/Armature/Pose API disabled... needs full recode too (wait for my doc!) - Game engine will need upgrade too - Depgraph code needs revision, cleanup, can be much faster! (But, compliments for Jean-Luc, it works like a charm!) - IK changed, it now doesnt use previous position to advance to next position anymore. That system looks nice (no flips) but is not well suited for NLA and background render. TODO LATER; We now can do loadsa new nifty features as well; like: - Kill PoseMode (can be option for armatures itself) - Make B-Bones (Bezier, Bspline, like for spines) - Move all silly button level edit to 3d window (like CTRL+I = add IK) - Much better & informative drawing - Fix action/nla editors - Put all ipos in Actions (object, mesh key, lamp color) - Add hooks - Null bones - Much more advanced constraints... Bugfixes; - OGL render (view3d header) had wrong first frame on anim render - Ipo 'recording' mode had wrong playback speed - Vertex-key mode now sticks to show 'active key', until frame change -Ton-

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes. Render engine is an owner of this context. This context is passed to all object update routines.

Bugfix [#32017] Infinite recursion in depsgraph material/node driver handling When initially coding this functionality, I was aware of the potential for infinite recursion here, just not how frequently such setups are actually used/created out in the wild (nodetree.ma_node -> ma -> ma.nodetree is all too common, and often even with several levels of indirection!). However, the best fix for these problems was not immediately clear. Alternatives considered included... 1) checking for common recursive cases. This was the solution employed for one of the early patches committed to try and get around this. However, it's all too easy to defeat these measures (with all the possible combinations of indirection node groups bring). 2) arbitrarily restricting recursion to only go down 2/3 levels? Has the risk of missing some deeply chained/nested drivers, but at least we're guaranteed to not get too bad. (Plus, who creates such setups anyway ;) *3) using the generic LIB_DOIT flag (check for tagged items and not recurse down there). Not as future-proof if some new code suddenly decides to start adding these tags to materials along the way, but is easiest to add, and should be flexible enough to catch most cases, since we only care that at some point those drivers will be evaluated if they're attached to stuff we're interested in. 4) introducing a separate flag for Materials indicating they've been checked already. Similar to 3) and solves the future-proofing, but this leads to... 5) why bother with remembering to clear flags before traversing for drivers to evaluate, when they should be tagged for evaluation like everything else? Downside - requires depsgraph refactor so that we can actually track the fact that there are dependencies to/from the material datablock, and not just to the object using said material. (i.e. Currently infeasible)

2.5: Blender "Animato" - New Animation System Finally, here is the basic (functional) prototype of the new animation system which will allow for the infamous "everything is animatable", and which also addresses several of the more serious shortcomings of the old system. Unfortunately, this will break old animation files (especially right now, as I haven't written the version patching code yet), however, this is for the future. Highlights of the new system: * Scrapped IPO-Curves/IPO/(Action+Constraint-Channels)/Action system, and replaced it with F-Curve/Action. - F-Curves (animators from other packages will feel at home with this name) replace IPO-Curves. - The 'new' Actions, act as the containers for F-Curves, so that they can be reused. They are therefore more akin to the old 'IPO' blocks, except they do not have the blocktype restriction, so you can store materials/texture/geometry F-Curves in the same Action as Object transforms, etc. * F-Curves use RNA-paths for Data Access, hence allowing "every" (where sensible/editable that is) user-accessible setting from RNA to be animated. * Drivers are no longer mixed with Animation Data, so rigs will not be that easily broken and several dependency problems can be eliminated. (NOTE: drivers haven't been hooked up yet, but the code is in place) * F-Curve modifier system allows useful 'large-scale' manipulation of F-Curve values, including (I've only included implemented ones here): envelope deform (similar to lattices to allow broad-scale reshaping of curves), curve generator (polynomial or py-expression), cycles (replacing the old cyclic extrapolation modes, giving more control over this). (NOTE: currently this cannot be tested, as there's not access to them, but the code is all in place) * NLA system with 'tracks' (i.e. layers), and multiple strips per track. (NOTE: NLA system is not yet functional, as it's only partially coded still) There are more nice things that I will be preparing some nice docs for soon, but for now, check for more details: http://lists.blender.org/pipermail/bf-taskforce25/2009-January/000260.html So, what currently works: * I've implemented two basic operators for the 3D-view only to Insert and Delete Keyframes. These are tempolary ones only that will be replaced in due course with 'proper' code. * Object Loc/Rot/Scale can be keyframed. Also, the colour of the 'active' material (Note: this should really be for nth material instead, but that doesn't work yet in RNA) can also be keyframed into the same datablock. * Standard animation refresh (i.e. animation resulting from NLA and Action evaluation) is now done completely separate from drivers before anything else is done after a frame change. Drivers are handled after this in a separate pass, as dictated by depsgraph flags, etc. Notes: * Drivers haven't been hooked up yet * Only objects and data directly linked to objects can be animated. * Depsgraph will need further tweaks. Currently, I've only made sure that it will update some things in the most basic cases (i.e. frame change). * Animation Editors are currently broken (in terms of editing stuff). This will be my next target (priority to get Dopesheet working first, then F-Curve editor - i.e. old IPO Editor) * I've had to put in large chunks of XXX sandboxing for old animation system code all around the place. This will be cleaned up in due course, as some places need special review. In particular, the particles and sequencer code have far too many manual calls to calculate + flush animation info, which is really bad (this is a 'please explain yourselves' call to Physics coders!).

Bugfix [#33970] Background Scene does not show animation of rigid body objects This was caused by multiple instantiations of the same basic problem. The rigidbody handling code often assumed that "scene" pointers referred to the scene where an object participating in the sim resided (and where the rigidbody world for that sim lived). However, when dealing with background sets, "scene" often only refers to the active scene, and not the set that the object actually came from. Hence, the rigidbody code would often (wrongly) conclude that there was nothing to do. For example, we may have the following backgound set/scene chaining scenario: "active" <-- ... <-- set i (rigidbody objects live here) <-- ... <-- set n The fix here is a multi-part fix: 1) Moved sim-world calculation from BKE_scene_update_newframe() to scene_update_tagged_recursive() + This is currently the only way that rigidbody sims in background sets will get calculated, as part of the recursion - These checks will get run on each update. <--- FIXME!!! 2) Tweaked depsgraph code so that when checking if there are any time-dependent features on objects to tag for updating, the checking is done relative to the scene that the object actually resides in (and not the active scene). Otherwise, even if we recalculate the sim, the affected objects won't get tagged for updating. This tagging is needed to actually flush the transforms out of the RigidBodyObject structs (written by the sim/cache) and into the Object transforms (obmat's) 3) Removed the requirement for rigidbody world to actually exist before we can flush rigidbody transforms. In many cases, it should be sufficient to assume that because the object with rigidbody data attached has been tagged for updates, it should have updates to perform. Of course, we still check on this data if we've got it, but that's only if the sim is in the active scene. - TODO: if we have further problems, we should investigate passing the "actual" scene down alongside the "active" scene for BKE_object_handle_update().

Color Management, Stage 2: Switch color pipeline to use OpenColorIO Replace old color pipeline which was supporting linear/sRGB color spaces only with OpenColorIO-based pipeline. This introduces two configurable color spaces: - Input color space for images and movie clips. This space is used to convert images/movies from color space in which file is saved to Blender's linear space (for float images, byte images are not internally converted, only input space is stored for such images and used later). This setting could be found in image/clip data block settings. - Display color space which defines space in which particular display is working. This settings could be found in scene's Color Management panel. When render result is being displayed on the screen, apart from converting image to display space, some additional conversions could happen. This conversions are: - View, which defines tone curve applying before display transformation. These are different ways to view the image on the same display device. For example it could be used to emulate film view on sRGB display. - Exposure affects on image exposure before tone map is applied. - Gamma is post-display gamma correction, could be used to match particular display gamma. - RGB curves are user-defined curves which are applying before display transformation, could be used for different purposes. All this settings by default are only applying on render result and does not affect on other images. If some particular image needs to be affected by this transformation, "View as Render" setting of image data block should be set to truth. Movie clips are always affected by all display transformations. This commit also introduces configurable color space in which sequencer is working. This setting could be found in scene's Color Management panel and it should be used if such stuff as grading needs to be done in color space different from sRGB (i.e. when Film view on sRGB display is use, using VD16 space as sequencer's internal space would make grading working in space which is close to the space using for display). Some technical notes: - Image buffer's float buffer is now always in linear space, even if it was created from 16bit byte images. - Space of byte buffer is stored in image buffer's rect_colorspace property. - Profile of image buffer was removed since it's not longer meaningful. - OpenGL and GLSL is supposed to always work in sRGB space. It is possible to support other spaces, but it's quite large project which isn't so much important. - Legacy Color Management option disabled is emulated by using None display. It could have some regressions, but there's no clear way to avoid them. - If OpenColorIO is disabled on build time, it should make blender behaving in the same way as previous release with color management enabled. More details could be found at this page (more details would be added soon): http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.64/Color_Management -- Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO integration and to Brecht van Lommel for some further development and code/ usecase review!
