Use object's displists for storing deformed tesselated curve. Was unable to
totally get rid of curve's displist because of how texture space is calculating.
move Object.update(...) to ID.update(). since depsgraph update function can now be called on ID types.
also changed how update flags work.
obj.update(scene, 1, 1, 1)
... is now
obj.update({'OBJECT', 'DATA', 'TIME'})
Don't pass scene anymore. This was used for recalculating text but I think this is better dont in a different function.
Surprising this wasnt noticed in a much more obvious case:
- Key Location, Move, Rotate, Undo-Rotate >> Resets to keyed location as well.
This was happening because DAG_on_load_update() was called on read_undosave(), flagging 'ob->adt->recalc |= ADT_RECALC_ANIM;'
Fix by adding an option to DAG_on_load_update(), not to recalculate time flags.
- loop over sequencer plugin and texture voxel paths.
- fix leak in python bpy.utils.blend_path() and use PyUnicode_DecodeFSDefault() to ensure correct paths with different encodings.
- operators to make paths absolute & relative now redraw the view.
only tags the ID and does the actual flush/update delayed, before the next
redraw. For objects the update was already delayed, just flushing wasn't
yet.
This should help performance in python and animation editors, by making
calls to RNA property update quicker. Still need to add calls in a few
places where this was previously avoided due to bad performance.
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
were not created when objects on visible layers depended on them, now
it uses the flushed layer to determine if the object data should be
recalculated.
Modifiers were being mistakenly recalculated at every frame as long as the object had animation, slowing things down due to incorrect depsgraph recalc tags.
Renamed OB_RECALC -> OB_RECALC_ALL to reduce future confusion. During this process, I noticed a few dubious usages of OB_RECALC, so it's best to use this commit as a guide of places to check on. Apart from the place responsible for this bug, I haven't changed any OB_RECALC -> OB_RECALC_OB/DATA in case that introduces more unforseen bugs now, making it more difficult to track the problems later (rename + value change can be confusing to identify the genuine typos).
PBVH used the same verts array as mesh data and shape key/reference key coords
were applying on the mesh data, so on some refreshing undeformed mesh was
displayed.
Added utility functions to get vert coords from key block, apply new vert coords
on keyblock and function to apply coords on bpvh, so now pbvh uses it's ovn
vertex array and no changes are making to the mesh data.
Additional change:
Store key block name in SculptUndoNode, so now shape wouldn't be copied to
wrong keyblock on undo
Since curve objects could have constructive modifiers, we can't
always avoid setting OB_RECALC_DATA to linked objects (displist
recalculation wouldn't enough for curves with such modifiers)
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.
This commit removes the Old Track method (used to be found under Object -> Animation -> Track), with all existing instances of this being converted to Track To Constraints. In fact, while performing this removal, I found that this was supposed to have happened in version 2.27 already, but for some reason the options were left in, and this function managed to survive for a further decade.
I've left the tracking axes around still, since it seems some curve tools still use that. However, that usage should probably get faded out in future too?
Misc notes:
* Fixed compiling error with constaints from harkyman's Maintain Volume patch.
* Subversion of 2.52 now bumped up to .2
properly on file loading. Some things get preserved on file save/load,
like object matrices and armature poses, but other things need to be remade
like derivedmeshes and displists. The latter were not tagged for recalc on
load causing them to be made on countall or redraw typically, so not in the
right order and dependencies on hidden layer were not done at all.
Now these get tagged for recalc and flags flushed on load. There shouldn't
be much if any slowdown on opening existing files, if there is it should be
fixable.
Highlights:
* Support for Multi-Target Variables
This was the main reason for this recode. Previously, variables could only be used to give some RNA property used as an input source to the driver a name. However, this meant that effects such as Rotational Difference couldn't be used in conjunction with other effects and/or settings to achieve the powerful results. Now, a variable can take several input targets, perform some interesting operations on them, and spit out a representative value based on that.
* New Variable Types
With the introduction of multi-target variables, there are now 3 types of variable that can be used: single property (i.e. the only type previously), Rotational Difference (angle between two bones), and Distance (distance between two objects or bones).
* New Driver Types
In addition to the existing 'Average', 'Sum', and 'Expression' types, there is now the additional options of 'Minimum' and 'Maximum'. These take the smallest/largest value that one of the variables evaluates to.
* Fix for Driver F-Curve colouring bug
Newly added drivers did not get automatically coloured in the Graph Editor properly. Was caused by inappropriate notifiers being used.
Notes:
* This commit breaks existing 2.5 files with drivers (in other words, they are lost forever).
* Rigify has been corrected to work with the new system. The PyAPI for accessing targets used for the variables could still be made nicer (using subclassing to directly access?), but that is left for later.
* Version patching for 2.49 files still needs to be put back in place.
* Mesh data/settings can now be animated. It is not recommended that geometry be animated directly, but other settings such as autosmooth, etc. can be...
* Code cleanups for depsgraph, making sure that drivers get included for all object data types.
* NURBS and Font animation data now appear in the animation editors.
* Fixed depsgraph tagging code for determining if the AnimData attached to object data blocks (i.e. animation for curve or lamp data) needs to be tagged for updates on frame changes. This means that animating curve settings now works.
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions

At last, this commit introduces the Spline IK Constraint to Blender. Spline IK is a constraint that makes n bones follow the shape of a specified curve.
Simply add a chain of bones, add a curve, add a Spline IK Constraint to the tip bone and set the number of bones in the chain to make it work. Or, try the following test file:
http://download.blender.org/ftp/incoming/250_splineik_spine01.blend
Screenshots of this in action (as proof):
http://download.blender.org/ftp/incoming/b250_splineik_001_before.pnghttp://download.blender.org/ftp/incoming/b250_splineik_001_after.png
I've implemented this in a similar way to how standard IK solvers are done. However, this code is currently not an IK plugin, since I imagine that it would be useful to be able to combine the 2 types of IK. This can be easily changed though :)
Finally, a few notes on what to expect still:
* Constraint blending currently doesn't affect this. Getting that to work correctly will take a bit more work still.
* Options for not affecting the root joint (to make it easier to attach the chain to a stump or whatever), and non-uniform scaling options have yet to be added. I've marked the places where they can be added though
* Control over the twisting of the chain still needs investigation.
Have fun!
* Changing to the ShapeKey editor now automatically enables the value sliders
* Filtering code for ShapeKey editor can now do AnimData block filtering too (internal details...)
* Silenced console warnings when inserting keyframes on F-Curves with no keyframes already (for Animation Editor sliders)
* Made the update code for keyframe transforms send more general depsgraph updates. Unfortuately, this still doesn't resolve the update problems with shapekeys
it would show you the last selected shape key until doing
another operation. This is confusing, and the Pin button allows
you to do the same kind of shape browsing.
* 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 :).
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.
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 :)
* Move function to compute visible screen layers to BKE.
* Use this now in the depsgraph, was still using this all layers
to flush. Still missing a way to get the current scene in
background mode..
* Also two more function to not require a scene pointer anymore:
* DAG_object_update_flags is now DAG_id_update_flags.
* DAG_ids_flush_update is now available next to DAG_scene_flush_update.
