Particles ========= Merge of the famous particle patch by Janne Karhu, a full rewrite of the Blender particle system. This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system. See the Cache API section on: http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint Documentation ============= These new features still need good docs for the release logs, help for this is appreciated.

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!).

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/

Fix for mirroring issues in particle mode, where the particles were not mirrored exactly, though the problem is not completely solved. The way local frames are computed for particles is still not fully symmetric, which shows especially on long hairs... Also made the shift+o subsurf switch work recursively into dupli-groups, did only the first level before.

#include "BKE_mesh.h"
Particles ========= - The render and realtime button for the particle system modifier and the enabled button for particles now work seperate again, made a bad design decision to tie them together. Now with only the render button and not realtime enabled it renders. - Fix for bug #7948: particle mode crash while constraining axis. - Fix for bug #7945: crash loading effector groups from an old file. - Fix for bug #7942: crash for reactor particles emitting from particles.

#include "BKE_cdderivedmesh.h"
Point Cache Refactoring ======================= Caching and Baking: - The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates. - There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles. - The cloth autoprotect feature was removed. - The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries. - The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions. - PointCache struct was added to DNA and is automatically allocated for each physics type. - Soft body now supports Bake Editing just like cloth. - Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now. Library Linking: - Added some more warnings to prevent editing settings on library linked objects. - Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked. - Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh). Physics UI: - Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth. - Tweaked field panel buttons to not jump around when changing options. - Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable. - I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers. - Fixed modifier error drawing glitch. Particles: - Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() .. - Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading. - Make particle threads work with autothreads. Continue Physics: - The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache. - This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics. Todo: - Point cache can get out of sync with and undo and changing a file without saving it. - Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion. - Menu item and/or buttons for Ctrl+B. - A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested. - The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

Point Cache Refactoring ======================= Caching and Baking: - The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates. - There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles. - The cloth autoprotect feature was removed. - The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries. - The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions. - PointCache struct was added to DNA and is automatically allocated for each physics type. - Soft body now supports Bake Editing just like cloth. - Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now. Library Linking: - Added some more warnings to prevent editing settings on library linked objects. - Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked. - Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh). Physics UI: - Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth. - Tweaked field panel buttons to not jump around when changing options. - Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable. - I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers. - Fixed modifier error drawing glitch. Particles: - Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() .. - Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading. - Make particle threads work with autothreads. Continue Physics: - The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache. - This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics. Todo: - Point cache can get out of sync with and undo and changing a file without saving it. - Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion. - Menu item and/or buttons for Ctrl+B. - A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested. - The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

"Fix" for #17636 Crashing bug - won't open a file - The cause was indeed corrupted particle settings which should have caused a deletion of the whole particle system. However the particle modifier was still left and that led to the crash. - A "fix" because there's really no way of knowing what caused the corruption of the particle settings. If anyone else gets this and can recreate I'd love to get a .blend. Now that there shouldn't be a crash anymore the symptom will be a missing particle system after file load in an object that had a particle system before.

New things for particle effectors: - For newtonian particles a "self effect" button in particle extras makes the particles be effected by themselves if a particle effector is defined for this system, currently this is a brute force method so things start getting slow with more than ~100 particles, but this will hopefully change in the future. - Two new effector types: charge and a Lennard-Jones potential based force (inter-molecular forces for example). -Charge is similar to spherical field except it changes behavior (attract/repulse) based on the effected particles charge field (negative/positive) like real particles with a charge. -The Lennard-Jones field is a very short range force with a behavior determined by the sizes of the effector and effected particle. At a distance smaller than the combined sizes the field is very repulsive and after that distance it's attractive. It tries to keep the particles at an equilibrium distance from each other. Particles need to be at a close proximity to each other to be effected by this field at all. - Particle systems can now have two effector fields (two slots in the fields panel). This allows to create particles which for example have both a charge and a Lennard-Jones potential.

2007-11-26 22:09:57 +00:00
Point Cache Refactoring ======================= Caching and Baking: - The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates. - There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles. - The cloth autoprotect feature was removed. - The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries. - The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions. - PointCache struct was added to DNA and is automatically allocated for each physics type. - Soft body now supports Bake Editing just like cloth. - Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now. Library Linking: - Added some more warnings to prevent editing settings on library linked objects. - Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked. - Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh). Physics UI: - Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth. - Tweaked field panel buttons to not jump around when changing options. - Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable. - I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers. - Fixed modifier error drawing glitch. Particles: - Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() .. - Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading. - Make particle threads work with autothreads. Continue Physics: - The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache. - This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics. Todo: - Point cache can get out of sync with and undo and changing a file without saving it. - Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion. - Menu item and/or buttons for Ctrl+B. - A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested. - The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

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.

Particles ========= Merge of the famous particle patch by Janne Karhu, a full rewrite of the Blender particle system. This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system. See the Cache API section on: http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint Documentation ============= These new features still need good docs for the release logs, help for this is appreciated.

Particles ========= - Texture orco coordinates for particles are now actual orcos instead of just the vertex positions, which means they are the same under deformations and the same as the ones on the mesh. - Particle distribution now uses these orcos to get consistent distributions independent of deformation. - This required changing the way orco's are computed for meshes. Now instead of generating an orco derivedmesh separately, the derivedmesh is generated alongside the regular one and stored in an orco custom data layer.

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

Now instead of generating an orco derivedmesh separately, the derivedmesh is generated alongside the regular one and stored in an orco custom data layer.

Particles ========= - Texture orco coordinates for particles are now actual orcos instead of just the vertex positions, which means they are the same under deformations and the same as the ones on the mesh. - Particle distribution now uses these orcos to get consistent distributions independent of deformation. - This required changing the way orco's are computed for meshes. Now instead of generating an orco derivedmesh separately, the derivedmesh is generated alongside the regular one and stored in an orco custom data layer.

Particles ========= Merge of the famous particle patch by Janne Karhu, a full rewrite of the Blender particle system. This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system.

Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

/* set correct ipo timing */
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!).

Fix for [#17642] Particule Hair - Vertex Group lenght don't works without Children - This feature had been removed from the code! So this is how things work now: For normal (non-child) hair particles the length vgroup is used if we're not in particle edit mode and if there are no child particles. So for example checking "Parents" in the visualization panel when children are in use will result in full length parent strands, this is a feature so that you can see how the parent's go to predict child behavior better, not a bug :)

Particles ========= - Texture orco coordinates for particles are now actual orcos instead of just the vertex positions, which means they are the same under deformations and the same as the ones on the mesh. - Particle distribution now uses these orcos to get consistent distributions independent of deformation. - This required changing the way orco's are computed for meshes. Now instead of generating an orco derivedmesh separately, the derivedmesh is generated alongside the regular one and stored in an orco custom data layer.

/* correct child ipo timing */
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!).

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!).

Particles ========= Merge of the famous particle patch by Janne Karhu, a full rewrite of the Blender particle system. This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system. See the Cache API section on: http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint Documentation ============= These new features still need good docs for the release logs, help for this is appreciated.

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/

/* apply different deformations to the child path */
Fix for bug [#8402] Hair particles don't react on changing of curve guides -guide calculation was accessing wrong pointers in hair calculation -now guides also respect the "apply effectors to children" - button, but not the "stiff" value -disabled guide calculation for initial hair calculation as it's all done dynamically later -few useless commented lines cleaned out

Fix for strand render + simplification + vector blur. With the number of strands changing between frames, vector blur couldn't work. Now speed vectors are interpolated from the surface. This also means child particles don't have to be computed in the previous and next frames, so saves time too.

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/

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

Fix for [#17642] Particule Hair - Vertex Group lenght don't works without Children - This feature had been removed from the code! So this is how things work now: For normal (non-child) hair particles the length vgroup is used if we're not in particle edit mode and if there are no child particles. So for example checking "Parents" in the visualization panel when children are in use will result in full length parent strands, this is a feature so that you can see how the parent's go to predict child behavior better, not a bug :)

- Regarding the Peach "hair effectors" request in the mailing list I coded quick support so that effectors now can effect combed hair too. Nothing special needed to use, just normal field effectors, although there is a new "stiff" parameter in extras panel.

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

/* apply guide curves to path data */
Fix for bug [#8402] Hair particles don't react on changing of curve guides -guide calculation was accessing wrong pointers in hair calculation -now guides also respect the "apply effectors to children" - button, but not the "stiff" value -disabled guide calculation for initial hair calculation as it's all done dynamically later -few useless commented lines cleaned out

- Regarding the Peach "hair effectors" request in the mailing list I coded quick support so that effectors now can effect combed hair too. Nothing special needed to use, just normal field effectors, although there is a new "stiff" parameter in extras panel. (Note, at least for now this only works with path visualization) - Keyed particles work again for all visualizations (previously only "path"), they still need some work though to be fully operational. - Keyed particles weren't saved or loaded correctly.

So this is how things work now: For normal (non-child) hair particles the length vgroup is used if we're not in particle edit mode and if there are no child particles. So for example checking "Parents" in the visualization panel when children are in use will result in full length parent strands, this is a feature so that you can see how the parent's go to predict child behavior better, not a bug :)

Fix for mirroring issues in particle mode, where the particles were not mirrored exactly, though the problem is not completely solved. The way local frames are computed for particles is still not fully symmetric, which shows especially on long hairs... Also made the shift+o subsurf switch work recursively into dupli-groups, did only the first level before.

Particles ========= Merge of the famous particle patch by Janne Karhu, a full rewrite of the Blender particle system. This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system. See the Cache API section on: http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint Documentation ============= These new features still need good docs for the release logs, help for this is appreciated.

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/

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!).

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.

New things for particle effectors: - For newtonian particles a "self effect" button in particle extras makes the particles be effected by themselves if a particle effector is defined for this system, currently this is a brute force method so things start getting slow with more than ~100 particles, but this will hopefully change in the future. - Two new effector types: charge and a Lennard-Jones potential based force (inter-molecular forces for example). -Charge is similar to spherical field except it changes behavior (attract/repulse) based on the effected particles charge field (negative/positive) like real particles with a charge. -The Lennard-Jones field is a very short range force with a behavior determined by the sizes of the effector and effected particle. At a distance smaller than the combined sizes the field is very repulsive and after that distance it's attractive. It tries to keep the particles at an equilibrium distance from each other. Particles need to be at a close proximity to each other to be effected by this field at all. - Particle systems can now have two effector fields (two slots in the fields panel). This allows to create particles which for example have both a charge and a Lennard-Jones potential.

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

Point Cache Refactoring ======================= Caching and Baking: - The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates. - There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles. - The cloth autoprotect feature was removed. - The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries. - The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions. - PointCache struct was added to DNA and is automatically allocated for each physics type. - Soft body now supports Bake Editing just like cloth. - Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now. Library Linking: - Added some more warnings to prevent editing settings on library linked objects. - Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked. - Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh). Physics UI: - Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth. - Tweaked field panel buttons to not jump around when changing options. - Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable. - I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers. - Fixed modifier error drawing glitch. Particles: - Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() .. - Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading. - Make particle threads work with autothreads. Continue Physics: - The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache. - This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics. Todo: - Point cache can get out of sync with and undo and changing a file without saving it. - Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion. - Menu item and/or buttons for Ctrl+B. - A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested. - The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested. - The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

2.5 Think global, act local! The old favorite G.scene gone! Man... that took almost 2 days. Also removed G.curscreen and G.edbo. Not everything could get solved; here's some notes. - modifiers now store current scene in ModifierData. This is not meant for permanent, but it can probably stick there until we cleaned the anim system and depsgraph to cope better with timing issues. - Game engine G.scene should become an argument for staring it. Didn't solve this yet. - Texture nodes should get scene cfra, but the current implementation is too tightly wrapped to do it easily.

DAG_object_flush_update(scene, ob, OB_RECALC_DATA);
Point Cache Refactoring ======================= Caching and Baking: - The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates. - There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles. - The cloth autoprotect feature was removed. - The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries. - The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions. - PointCache struct was added to DNA and is automatically allocated for each physics type. - Soft body now supports Bake Editing just like cloth. - Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now. Library Linking: - Added some more warnings to prevent editing settings on library linked objects. - Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked. - Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh). Physics UI: - Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth. - Tweaked field panel buttons to not jump around when changing options. - Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable. - I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers. - Fixed modifier error drawing glitch. Particles: - Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() .. - Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading. - Make particle threads work with autothreads. Continue Physics: - The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache. - This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics. Todo: - Point cache can get out of sync with and undo and changing a file without saving it. - Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion. - Menu item and/or buttons for Ctrl+B. - A system("rm ..") was changed to remove() since the former is very slow for clearing point caches.

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!).

This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system. See the Cache API section on: http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint Documentation ============= These new features still need good docs for the release logs, help for this is appreciated.

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!).

- Regarding the Peach "hair effectors" request in the mailing list I coded quick support so that effectors now can effect combed hair too. Nothing special needed to use, just normal field effectors, although there is a new "stiff" parameter in extras panel. (Note, at least for now this only works with path visualization) - Keyed particles work again for all visualizations (previously only "path"), they still need some work though to be fully operational. - Keyed particles weren't saved or loaded correctly.

/* correct child ipo timing */
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!).

Fix for strand render + simplification + vector blur. With the number of strands changing between frames, vector blur couldn't work. Now speed vectors are interpolated from the surface. This also means child particles don't have to be computed in the previous and next frames, so saves time too.

- Particle-particle effectors we're quite unstable and not accurate at all. Now this should be fixed (especially with other integrators than euler) as the needed inter-frame effector particle positions are interpolated properly from the current and previous positions (previously only the most recent position was used). - In practice this removes the dependency of particle simulations from the update order of objects and different particle systems inside objects. - As a nice side effect out of this we also get fully correct birth positions for "near reactor particles" (previously for example smoke trail reactor particles were not born smoothly along the target particles path).

This includes: - Emitter, Hair and Reactor particle types. - Newtonian, Keyed and Boids physics. - Various particle visualisation and rendering types. - Vertex group and texture control for various properties. - Interpolated child particles from parents. - Hair editing with combing, growing, cutting, .. . - Explode modifier. - Harmonic, Magnetic fields, and multiple falloff types. .. and lots of other things, some more info is here: http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc The new particle system cannot be backwards compatible. Old particle systems are being converted to the new system, but will require tweaking to get them looking the same as before. Point Cache =========== The new system to replace manual baking, based on automatic caching on disk. This is currently used by softbodies and the particle system. See the Cache API section on: http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint Documentation ============= These new features still need good docs for the release logs, help for this is appreciated.

- Regarding the Peach "hair effectors" request in the mailing list I coded quick support so that effectors now can effect combed hair too. Nothing special needed to use, just normal field effectors, although there is a new "stiff" parameter in extras panel. (Note, at least for now this only works with path visualization) - Keyed particles work again for all visualizations (previously only "path"), they still need some work though to be fully operational. - Keyed particles weren't saved or loaded correctly.

Misc Render Features ==================== - "From Dupli" option for orco and uv texture coordinates. For dupliverts, duplifaces and dupli particles, this uses the orco and uv at the point on the parent surface. Can for example be used for texturing feathers and leafs. Note that uv only works for duplifaces and particles emitted from faces, these are not defined at vertices. - "Width Fade" option for strand render, to fade out along the width of the strand. Committing this so it can be tested, might be changed or removed even, if it doesn't give nice results.
