This uses pythons GC so its no overhead during runtime but makes removing ID's slower.
Commented definition 'USE_PYRNA_INVALIDATE_GC' for now, so no functional change.
* For rendering every object's inverse matrix "ob->imat" needs to
be in render view coordinates, but for drawing in 3d view it needs
to be in global coordinates. Originally (way back in historical
times) ob->imat was only used for rendering, but over the years
other uses came up too. Before 2.5 this wasn't a problem as
rendering was a totally blocking operation, but with the new
"interactive ui while rendering" the problems started. Basically
any update that redrew the 3d view while rendering (like rotating
the scene with mouse) updated the inverse matrix into global
coordinates thus invalidating it for the render, leading to all
kinds of strange discontinuities with textures and volumetrics.
* Problems were very easy to achieve using orco/object coordinates
for pretty much any textures (bump, point density, volume, sky),
for examples see bug reports 24906 and 25229. Render baking normals
in object coordinates was wrong most of the time too.
* Now there is a separate inverse matrix ob->imat_ren that's
calculated at the beginning of rendering and is used in all places
inside render code where it's needed. This way the original ob->imat
can change at will during rendering without causing problems.
* Moved ICON_BLENDER away from (0,0) spot in blenderbuttons, since ICON_BLENDER=0 define is conflicting ICON_NULL define as well as with logic checks for nonzero icon id.
* This solved bug where ICON_BLENDER can't be set from Python as well as when using new UI functions from within Blender.
- Invalid shape when deformation mesh was disabled befoe undoing
- Crash when deformation modifier was enabled before undoing
Still got problems with undoing multires changes when toggling modifiers.
From the tracker:::
Issues fixed:
- ConeTwist-constraint's params weren't making it to the CcdPhysicsEnvironment, also added Hinge's params.
- UI wasn't using angles where applicable.
- btHingeConstraint's constructor can create frame-matrices which don't align so the hinge doesn's start at 0 degree tilt.
This is an issue when setting limits.
Changes:
- UI: Hinge limits can be set (and disabled).
- UI: ConeTwist only has max-limits and only the twistX can be disabled
- PyApi via rna_constraint.c: added the functions limit_xyz_min, limit_xyz_max (for 6dof), limit_angle_xyz_min,
limit_angle_xyz_max (for 6dof), limit_angle_x_min, limit_angle_x_max (for hinge).
- PyApi: dropped python-function limit_cone_min.
.:. Extra:
UI Changes:
- renamed "RigidBody Joint" to "Rigid Boidy Joint"
- reorganized UI to conform with other parameters (e.g. Limit Rot)
- added dis/active all over the place :)
to sequential error by adopting a two-pass smoothing strategy instead.
This seems to give some minimal reductions in the amounts of unwanted
shrinkage that occurs
- Fixed problem where just trying to replace existing keyframes would
result in the intepolation set on that keyframe to get lost. This was
mostly an issue if trying to re-block some animation in the middle of
a shot, with the rest of the keys set to Bezier, but the first
keyframe in this new segment needing to be Constant so that we don't
get sloppy automatic interpolation in the way
- Hooked up Media-Play/Stop/Next/Prev controls to animation playback
and keyframe jumping functionality in default keymap in addition the
existing controls. I'm also considering whether to migrate Next/Prev
Keyframe key mappings off the Ctrl-PageUp/Down keys for a more
ergonomic option (i.e. shift <, shift >)
Two bugs in one:
- Lukas commit monday for new group/socket handling accidentally removed
to set socketype in stacks, which as used by (texture) nodes to detect
whether value, color or vector had to be read.
Result was that all texture nodes were rendering as B&W
- Old 2.5 bug: preview renders for texture nodes didn't call a
NodeEndExec function, which gave crashes on deleting nodes.
The change in interface_hanlers.c is only a comment to explain
how keymaps are being found.
