2.5: Added first particle panel, and an RNA property to retrieve the active particle system.

import bpy
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 :).

First new particle code: -Many things not yet working properly :) -Experimental new (hopefully more logical) categorization of buttons, feedback on this is very welcome. -Separate render & draw types, for example now there is actually a render option "halo" instead of all the different point draw types. -Particles get recalculated only from buttons that actually change something that has to be recalculated, for example changing visualization doesn't reset particles any more. -Boid physics buttons are still missing as I'm currently redoing the whole boids code. -Point caching is still very wip, so baking is not possible for example, but I added a few cache baking flags for rna that were/will be needed for particle buttons logic.

Point cache editing: - Baked point caches for particles, cloth and softbody can now be edited in particle mode. * This overwrites the old cloth/sb cache editmode editing. * The type of editable system is chosen from a menu. * For particles the current particle system and it's current cache are used. - Currently this only works for caches that are in memory, but some automatic conversion from disk to memory and back can be implemented later. - All tools from hair editing can't be applied to point caches and are hidden in the tool panel and specials menu. Some functionality like subdividing paths can be later implemented in a slightly different way from how it works for hair. - Code is not yet optimized for speed, so editing might be slow sometimes. Known issues: - Cloth doesn't update properly while in particle mode, due to the way cloth modifier currently works. Daniel can you check on this? - As "particle mode" is not only for particles any more some other name would be in place? - Better icons are needed for the path, point, and tip-modes as the current icons from mesh edit mode are quite misleading. - Direct editing of point velocities is not yet implemented, but will be in the future. Other changes: - Hair editing doesn't require a "make editable" button press any more. - Multiple caches in single particle system disables changing emission properties. - Unified ui code for all point cache panels. * Defined in buttons_particle.py and imported for cloth, smoke & softbody. - Proper disabling of properties in ui after baking point caches. (Daniel could you please make needed disable code for smoke panels as their functionality is not familiar to me.) - Hair weight brush has been removed. Once hair dynamics is re-implemented I'll code a more useable alternative to the functionality. Bug fixes: - Unlinking particle settings crashed. - Deleting the active object with particles in the scene crashed. - Softbody didn't write point caches correctly on save.

Other code changes: - KDTree now supports range search as it's needed for new boids. - "Keyed particle targets" renamed as general "particle targets", as they're needed for boids too.

External cache Particle point cache can now be loaded from external files. - Activated by "external" checkbox in cache panel and giving proper folder path and file name identifier. - External cache panel has controls for particle emission start, end, lifetime and random lifetime. These should be set according to the external data for correct playback. - External files should be named "identifier_frame_index.bphys" or "identifier_frame.bphys" where: * "identifier" is a freely choseable name. * "frame" is the cached frame number. ** Six digits padded with zeros!, for example "000024". * "index" can be used to tell caches with the same identifier apart. ** Two digits starting from zero. ** The index and the underscore before are optional. If no index is present the index number in ui should be set to -1. - Cache file format is pure floating point numbers (in binary, not text!) with each particle's data one after the other with the following data members: * 3 floats: particle's location vector * 3 floats: particle's velocity vector (per second) * 4 floats: particle's rotation quaternion * 3 floats: particle's angular velocity vector (per second) * 1 float: frame of the actual data (this can be non-integer for particles that are born or die between two integer frames, but otherwise should be the same as the "frame" in the file name) - Cache files don't have to exist for each frame. * Frames without actual data are interpolated from surrounding frames that have data (extrapolation is not supported). - Cache file formats with extended (or reduced even) data members are in future plans for easier usage. - Current code only does particles, don't yet know if it's applicable to cloth or sb. - Known issue: endianness can't yet be handled in any way. Other changes: New hard limits for many particle parameters. Some examples: - Maximum amount of particles: 10M particles :) And before you all go and crash your Blender trying this out remember that this limit is only for those freaks who really have the machine power to handle it. 10M particles alone take around 2.2 Gb of memory / disk space in saved file and each cached frame takes around 0.5 Gb of memory / disk space depending on cache mode. * Known issue: To actually use this many particles they most likely need to be allocated in parts as taking hold of a 2.2Gb chunk of memory at once is probably not ok with any operating system. - Maximum amount of children: 100k children/particle (1T childparticles here we come :D) - Kink frequency: -100k to 100k half-rotations (really strange the previous limit was only from zero upwards) - Path draw steps: 10 (power of 2 remember) - Path render steps: 20 (power of 2 also!! If over 1M segments doesn't get you smooth paths then I think nothing will!)

Particles cleanup, optimizations and some small new stuff. New stuff - Bending springs for hair dynamics. Code cleanup & optimization - Disabled reactor particles temporarily for cleanup, it's a clumsy system that will be replaced with something better. - Removed child seams, something better will come here too :) - Normal particle drawing data is now saved between redraws if the particles don't move between redraws. * For example rotating the 3d view is now realtime even with 1M particles. - Many random values for particles now come from a lookup table making things much faster. - Most accessed small point cache functions are now much faster as macros. - Lot's of general code cleanup. - Nothing big should have changed so if something doesn't work like it used to it's probably just a typo somewhere :)

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.

Keyed physics refresh: - Keyed targets in one list instead of "chaining", this opens up many more possibilities than before and is much less obscure. - Better keyed timing possibilities (time & duration in frames). - Looping over keyed targets list. Other changes: - New child setting "length" with threshold (great for guard & underfur with a single particle system) - Modularization of path interpolation code. - Cleared "animateable" flags from many particle settings that shouldn't be animateable. Fixes: - Keyed particles weren't copied properly (ancient bug). - Hair rotations depended on global z-axis for root rotation so downward facing strands could flip rotation randomly. Now initial hair rotation is derived from face dependent hair matrix. (This caused for example ugly flipping of child strands on some cases). - Children from faces weren't calculated straight after activating them. - Multiple disk cache fixes: * Disk cache didn't work correctly with frame steps. * Conversion from memory cache to disk cache didn't work with cloth. * Disk cache crashed on some frames trying to close an already closed cache file. * Trails didn't work with disk cached particles. - Child rough effects were effected by emitter object loc/rot making them next to useless with animation, why didn't anybody tell me this!! - Lots of random code cleanup.

Other changes/fixes: - Particle mode editing flag wasn't saved properly. - Some old files with edited hair didn't load correctly. - Disabled delete & specials menu in particle mode for non-hair editing. - Fixed yet one more cloth & softbody pointcache update issue. - Disconnect/connect hair now uses only the deformed mesh so it works correctly also for subsurfed emitters. - Hair editing now updates correctly with a moving emitter.

Pointcache refresh part 1: * Particles support larger than 1 frame changes, bigger frame changes can result in inaccurate results, but it's super fast and you get a nice feeling of how the particles behave! * "Cache to current frame" button calculates the exact result of particles at current frame. * Current state of cache can be protected by making it a bake. * Cache is now in memory by default, disk cache is an option. * Only "viewport %" number of particles are calculated and cached in viewport, baking and rendering calculate all particles. * Info on cached frames and memory usage given in ui. * Support for exact "autocaching" of changes and large frame changes(disabled for now until exact place in event system is decided) * "Continue physics" is probably deprecated after this and should be removed once sb & cloth use the new cache code. Todo: * Make softbody & cloth use the new cache things. Other changes: * Some cleanup of particle buttons.

Initial code for boids v2 Too many new features to list! But here are the biggies: - Boids can move on air and/or land, or climb a goal object. - Proper interaction with collision objects. * Closest collision object in negative z direction is considered as ground. * Other collision objects are obstacles and boids collide with them. - Boid behavior rules are now added to a dynamic list. * Many new rules and many still not implemented. * Different rule evaluation modes (fuzzy, random, average). - Only particle systems defined by per system "boid relations" are considered for simulation of that system. * This is in addition to the boids own system of course. * Relations define other systems as "neutral", "friend" or "enemy". - All effectors now effect boid physics, not boid brains. * This allows forcing boids somewhere. * Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength). Known issue: - Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly. - Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code. Other new features: - Particle systems can now be named separately from particle settings. * Default name for particle settings is now "ParticleSettings" instead of "PSys" - Per particle system list of particle effector weights. * Enables different effection strengths for particles from different particle systems with without messing around with effector group setting. Other code changes: - KDTree now supports range search as it's needed for new boids. - "Keyed particle targets" renamed as general "particle targets", as they're needed for boids too. (this might break some files saved with new keyed particles) Bug fixes: - Object & group visualizations didn't work. - Interpolating pointcache didn't do rotation.

External cache Particle point cache can now be loaded from external files. - Activated by "external" checkbox in cache panel and giving proper folder path and file name identifier. - External cache panel has controls for particle emission start, end, lifetime and random lifetime. These should be set according to the external data for correct playback. - External files should be named "identifier_frame_index.bphys" or "identifier_frame.bphys" where: * "identifier" is a freely choseable name. * "frame" is the cached frame number. ** Six digits padded with zeros!, for example "000024". * "index" can be used to tell caches with the same identifier apart. ** Two digits starting from zero. ** The index and the underscore before are optional. If no index is present the index number in ui should be set to -1. - Cache file format is pure floating point numbers (in binary, not text!) with each particle's data one after the other with the following data members: * 3 floats: particle's location vector * 3 floats: particle's velocity vector (per second) * 4 floats: particle's rotation quaternion * 3 floats: particle's angular velocity vector (per second) * 1 float: frame of the actual data (this can be non-integer for particles that are born or die between two integer frames, but otherwise should be the same as the "frame" in the file name) - Cache files don't have to exist for each frame. * Frames without actual data are interpolated from surrounding frames that have data (extrapolation is not supported). - Cache file formats with extended (or reduced even) data members are in future plans for easier usage. - Current code only does particles, don't yet know if it's applicable to cloth or sb. - Known issue: endianness can't yet be handled in any way. Other changes: New hard limits for many particle parameters. Some examples: - Maximum amount of particles: 10M particles :) And before you all go and crash your Blender trying this out remember that this limit is only for those freaks who really have the machine power to handle it. 10M particles alone take around 2.2 Gb of memory / disk space in saved file and each cached frame takes around 0.5 Gb of memory / disk space depending on cache mode. * Known issue: To actually use this many particles they most likely need to be allocated in parts as taking hold of a 2.2Gb chunk of memory at once is probably not ok with any operating system. - Maximum amount of children: 100k children/particle (1T childparticles here we come :D) - Kink frequency: -100k to 100k half-rotations (really strange the previous limit was only from zero upwards) - Path draw steps: 10 (power of 2 remember) - Path render steps: 20 (power of 2 also!! If over 1M segments doesn't get you smooth paths then I think nothing will!)

Initial code for boids v2 Too many new features to list! But here are the biggies: - Boids can move on air and/or land, or climb a goal object. - Proper interaction with collision objects. * Closest collision object in negative z direction is considered as ground. * Other collision objects are obstacles and boids collide with them. - Boid behavior rules are now added to a dynamic list. * Many new rules and many still not implemented. * Different rule evaluation modes (fuzzy, random, average). - Only particle systems defined by per system "boid relations" are considered for simulation of that system. * This is in addition to the boids own system of course. * Relations define other systems as "neutral", "friend" or "enemy". - All effectors now effect boid physics, not boid brains. * This allows forcing boids somewhere. * Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength). Known issue: - Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly. - Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code. Other new features: - Particle systems can now be named separately from particle settings. * Default name for particle settings is now "ParticleSettings" instead of "PSys" - Per particle system list of particle effector weights. * Enables different effection strengths for particles from different particle systems with without messing around with effector group setting. Other code changes: - KDTree now supports range search as it's needed for new boids. - "Keyed particle targets" renamed as general "particle targets", as they're needed for boids too. (this might break some files saved with new keyed particles) Bug fixes: - Object & group visualizations didn't work. - Interpolating pointcache didn't do rotation.

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 :).

First new particle code: -Many things not yet working properly :) -Experimental new (hopefully more logical) categorization of buttons, feedback on this is very welcome. -Separate render & draw types, for example now there is actually a render option "halo" instead of all the different point draw types. -Particles get recalculated only from buttons that actually change something that has to be recalculated, for example changing visualization doesn't reset particles any more. -Boid physics buttons are still missing as I'm currently redoing the whole boids code. -Point caching is still very wip, so baking is not possible for example, but I added a few cache baking flags for rna that were/will be needed for particle buttons logic.

Fixes: - Keyed particles weren't copied properly (ancient bug). - Hair rotations depended on global z-axis for root rotation so downward facing strands could flip rotation randomly.

Fixes: - Keyed particles weren't copied properly (ancient bug). - Hair rotations depended on global z-axis for root rotation so downward facing strands could flip rotation randomly. Now initial hair rotation is derived from face dependent hair matrix. (This caused for example ugly flipping of child strands on some cases). - Children from faces weren't calculated straight after activating them. - Multiple disk cache fixes: * Disk cache didn't work correctly with frame steps. * Conversion from memory cache to disk cache didn't work with cloth. * Disk cache crashed on some frames trying to close an already closed cache file. * Trails didn't work with disk cached particles. - Child rough effects were effected by emitter object loc/rot making them next to useless with animation, why didn't anybody tell me this!! - Lots of random code cleanup.

External cache Particle point cache can now be loaded from external files. - Activated by "external" checkbox in cache panel and giving proper folder path and file name identifier. - External cache panel has controls for particle emission start, end, lifetime and random lifetime. These should be set according to the external data for correct playback. - External files should be named "identifier_frame_index.bphys" or "identifier_frame.bphys" where: * "identifier" is a freely choseable name. * "frame" is the cached frame number. ** Six digits padded with zeros!, for example "000024". * "index" can be used to tell caches with the same identifier apart. ** Two digits starting from zero. ** The index and the underscore before are optional. If no index is present the index number in ui should be set to -1. - Cache file format is pure floating point numbers (in binary, not text!) with each particle's data one after the other with the following data members: * 3 floats: particle's location vector * 3 floats: particle's velocity vector (per second) * 4 floats: particle's rotation quaternion * 3 floats: particle's angular velocity vector (per second) * 1 float: frame of the actual data (this can be non-integer for particles that are born or die between two integer frames, but otherwise should be the same as the "frame" in the file name) - Cache files don't have to exist for each frame. * Frames without actual data are interpolated from surrounding frames that have data (extrapolation is not supported). - Cache file formats with extended (or reduced even) data members are in future plans for easier usage. - Current code only does particles, don't yet know if it's applicable to cloth or sb. - Known issue: endianness can't yet be handled in any way. Other changes: New hard limits for many particle parameters. Some examples: - Maximum amount of particles: 10M particles :) And before you all go and crash your Blender trying this out remember that this limit is only for those freaks who really have the machine power to handle it. 10M particles alone take around 2.2 Gb of memory / disk space in saved file and each cached frame takes around 0.5 Gb of memory / disk space depending on cache mode. * Known issue: To actually use this many particles they most likely need to be allocated in parts as taking hold of a 2.2Gb chunk of memory at once is probably not ok with any operating system. - Maximum amount of children: 100k children/particle (1T childparticles here we come :D) - Kink frequency: -100k to 100k half-rotations (really strange the previous limit was only from zero upwards) - Path draw steps: 10 (power of 2 remember) - Path render steps: 20 (power of 2 also!! If over 1M segments doesn't get you smooth paths then I think nothing will!)

Sorry, three commits in one, became difficult to untangle.. Editors Modules * render/ module added in editors, moved the preview render code there and also shading related operators. * physics/ module made more consistent with other modules. renaming files, making a single physics_ops.c for operators and keymaps. Also move all particle related operators here now. * space_buttons/ now should have only operators relevant to the buttons specificially. Updates & Notifiers * Material/Texture/World/Lamp can now be passed to DAG_id_flush_update, which will go back to a callback in editors. Eventually these should be in the depsgraph itself, but for now this gives a unified call for doing updates. * GLSL materials are now refreshed on changes. There's still various cases missing, * Preview icons now hook into this system, solving various update cases that were missed before. * Also fixes issue in my last commit, where some preview would not render, problem is avoided in the new system. Icon Rendering * On systems with support for non-power of two textures, an OpenGL texture is now used instead of glDrawPixels. This avoids problems with icons get clipped on region borders. On my Linux desktop, this gives an 1.1x speedup, and on my Mac laptop a 2.3x speedup overall in redrawing the full window, with the default setup. The glDrawPixels implementation on Mac seems to have a lot of overhread. * Preview icons are now drawn using proper premul alpha, and never faded so you can see them clearly. * Also tried to fix issue with texture node preview rendering, globals can't be used with threads reliably.

Initial code for boids v2 Too many new features to list! But here are the biggies: - Boids can move on air and/or land, or climb a goal object. - Proper interaction with collision objects. * Closest collision object in negative z direction is considered as ground. * Other collision objects are obstacles and boids collide with them. - Boid behavior rules are now added to a dynamic list. * Many new rules and many still not implemented. * Different rule evaluation modes (fuzzy, random, average). - Only particle systems defined by per system "boid relations" are considered for simulation of that system. * This is in addition to the boids own system of course. * Relations define other systems as "neutral", "friend" or "enemy". - All effectors now effect boid physics, not boid brains. * This allows forcing boids somewhere. * Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength). Known issue: - Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly. - Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code. Other new features: - Particle systems can now be named separately from particle settings. * Default name for particle settings is now "ParticleSettings" instead of "PSys" - Per particle system list of particle effector weights. * Enables different effection strengths for particles from different particle systems with without messing around with effector group setting. Other code changes: - KDTree now supports range search as it's needed for new boids. - "Keyed particle targets" renamed as general "particle targets", as they're needed for boids too. (this might break some files saved with new keyed particles) Bug fixes: - Object & group visualizations didn't work. - Interpolating pointcache didn't do rotation.

Keyed physics refresh: - Keyed targets in one list instead of "chaining", this opens up many more possibilities than before and is much less obscure. - Better keyed timing possibilities (time & duration in frames). - Looping over keyed targets list. Other changes: - New child setting "length" with threshold (great for guard & underfur with a single particle system) - Modularization of path interpolation code. - Cleared "animateable" flags from many particle settings that shouldn't be animateable. Fixes: - Keyed particles weren't copied properly (ancient bug). - Hair rotations depended on global z-axis for root rotation so downward facing strands could flip rotation randomly. Now initial hair rotation is derived from face dependent hair matrix. (This caused for example ugly flipping of child strands on some cases). - Children from faces weren't calculated straight after activating them. - Multiple disk cache fixes: * Disk cache didn't work correctly with frame steps. * Conversion from memory cache to disk cache didn't work with cloth. * Disk cache crashed on some frames trying to close an already closed cache file. * Trails didn't work with disk cached particles. - Child rough effects were effected by emitter object loc/rot making them next to useless with animation, why didn't anybody tell me this!! - Lots of random code cleanup.

A bunch of fun stuff now possible because of new pointcache code: * Baked normal particles can now use the "Path" visualization. * Path "max length" & "abs length" are now history: - New option to set path start & end times + random variation to length. - Much more flexible (and calculated better) than previous options. - This works with parents, children, hair & normal particles unlike old length option. - Only known issue for now is that children from faces don't get calculated correctly when using path start time. * New option "trails" for "halo", "line" and "billboard" visualizations: - Draws user controllable number of particle instances along particles path backwards from current position. - Works with children too for cool/weird visualizations that weren't possible before. * Normal particle children's velocities are now approximated better when needed so that "line" visualization trails will look nice. * New particle instance modifier options: - "path"-option works better and has controllable (max)position along path (with random variation possible). - "keep shape"-option for hair, keyed, or baked particles allows to place the instances to a single point (with random variation possible) along particle path. - "axis" option to make rotation handling better (still not perfect, but will have to do for now). Some fixes & cleanup done along the way: * Random path length didn't work for non-child particles. * Cached & unborn particles weren't reset to emit locations. * Particle numbers weren't drawn in the correct place. * Setting proper render & draw visualizations was lost somewhere when initializing new particle settings. * Changing child mode wasn't working correctly. * Some cleanup & modularization of particle child effector code and particle drawing & rendering code. * Object & group visualizations didn't work. * Child simplification didn't work.

A bunch of fun stuff now possible because of new pointcache code: * Baked normal particles can now use the "Path" visualization. * Path "max length" & "abs length" are now history: - New option to set path start & end times + random variation to length. - Much more flexible (and calculated better) than previous options. - This works with parents, children, hair & normal particles unlike old length option. - Only known issue for now is that children from faces don't get calculated correctly when using path start time. * New option "trails" for "halo", "line" and "billboard" visualizations: - Draws user controllable number of particle instances along particles path backwards from current position. - Works with children too for cool/weird visualizations that weren't possible before. * Normal particle children's velocities are now approximated better when needed so that "line" visualization trails will look nice. * New particle instance modifier options: - "path"-option works better and has controllable (max)position along path (with random variation possible). - "keep shape"-option for hair, keyed, or baked particles allows to place the instances to a single point (with random variation possible) along particle path. - "axis" option to make rotation handling better (still not perfect, but will have to do for now). Some fixes & cleanup done along the way: * Random path length didn't work for non-child particles. * Cached & unborn particles weren't reset to emit locations. * Particle numbers weren't drawn in the correct place. * Setting proper render & draw visualizations was lost somewhere when initializing new particle settings. * Changing child mode wasn't working correctly. * Some cleanup & modularization of particle child effector code and particle drawing & rendering code. * Object & group visualizations didn't work. * Child simplification didn't work.

Other changes: - New child setting "length" with threshold (great for guard & underfur with a single particle system) - Modularization of path interpolation code. - Cleared "animateable" flags from many particle settings that shouldn't be animateable. Fixes: - Keyed particles weren't copied properly (ancient bug). - Hair rotations depended on global z-axis for root rotation so downward facing strands could flip rotation randomly.

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 :).

Initial code for boids v2 Too many new features to list! But here are the biggies: - Boids can move on air and/or land, or climb a goal object. - Proper interaction with collision objects. * Closest collision object in negative z direction is considered as ground. * Other collision objects are obstacles and boids collide with them. - Boid behavior rules are now added to a dynamic list. * Many new rules and many still not implemented. * Different rule evaluation modes (fuzzy, random, average). - Only particle systems defined by per system "boid relations" are considered for simulation of that system. * This is in addition to the boids own system of course. * Relations define other systems as "neutral", "friend" or "enemy". - All effectors now effect boid physics, not boid brains. * This allows forcing boids somewhere. * Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength). Known issue: - Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly. - Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code. Other new features: - Particle systems can now be named separately from particle settings. * Default name for particle settings is now "ParticleSettings" instead of "PSys" - Per particle system list of particle effector weights. * Enables different effection strengths for particles from different particle systems with without messing around with effector group setting.

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(..).

Initial code for boids v2 Too many new features to list! But here are the biggies: - Boids can move on air and/or land, or climb a goal object. - Proper interaction with collision objects. * Closest collision object in negative z direction is considered as ground. * Other collision objects are obstacles and boids collide with them. - Boid behavior rules are now added to a dynamic list. * Many new rules and many still not implemented. * Different rule evaluation modes (fuzzy, random, average). - Only particle systems defined by per system "boid relations" are considered for simulation of that system. * This is in addition to the boids own system of course. * Relations define other systems as "neutral", "friend" or "enemy". - All effectors now effect boid physics, not boid brains. * This allows forcing boids somewhere. * Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength). Known issue: - Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly. - Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code. Other new features: - Particle systems can now be named separately from particle settings. * Default name for particle settings is now "ParticleSettings" instead of "PSys" - Per particle system list of particle effector weights. * Enables different effection strengths for particles from different particle systems with without messing around with effector group setting.

Pointcache refresh part 1: * Particles support larger than 1 frame changes, bigger frame changes can result in inaccurate results, but it's super fast and you get a nice feeling of how the particles behave! * "Cache to current frame" button calculates the exact result of particles at current frame. * Current state of cache can be protected by making it a bake. * Cache is now in memory by default, disk cache is an option. * Only "viewport %" number of particles are calculated and cached in viewport, baking and rendering calculate all particles. * Info on cached frames and memory usage given in ui. * Support for exact "autocaching" of changes and large frame changes(disabled for now until exact place in event system is decided) * "Continue physics" is probably deprecated after this and should be removed once sb & cloth use the new cache code. Todo: * Make softbody & cloth use the new cache things. Other changes: * Some cleanup of particle buttons.

Hair dynamics with cloth simulation - Hair dynamics have their own panel in particle settings with the settings from cloth panel that apply to hair. - Basic internal friction force to quickly emulate self collisions and volume preservation. (Still very early code, but gives some idea of what's possible). - Softbody simulation is no longer used for hair. * Old files with sb dynamics should just load the hair without dynamics so new dynamics can be applied. * Invasion of particles exceptions in sb code is finally over. - Collisions with other objects are disabled for now and will be worked out in the future. Other changes/fixes: - Particle mode editing flag wasn't saved properly. - Some old files with edited hair didn't load correctly. - Disabled delete & specials menu in particle mode for non-hair editing. - Fixed yet one more cloth & softbody pointcache update issue. - Disconnect/connect hair now uses only the deformed mesh so it works correctly also for subsurfed emitters. - Hair editing now updates correctly with a moving emitter.

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 :).

UI Buttons: * Context now allows pinning a datablock, independent of selection. * Initial ID browse buttons for most buttons tabs. * Browsing from world to texture now displays world textures again, but is a bit of a hack, not sure there is a right way to do this. * There's a button to switch between active materials and textures now, only temporary though. * There's some code to put context part in own region, disabled still because it doesn't work that well yet.
