Now the bounding box for the light cache's voxel grid is calculated in
global space, rather than camera space as it was previously. This fixes
flickering lighting on static volumes with camera motion, caused by
the camera space bounding box changing from frame to frame.
Bugfix: free_imbuf_seq() was closing IMB anim handles on nearly every
change of RNA variables. This can be *very* slow, if you twiddle with
parameters during playback. Especially multicam editing...
Now: we close IMB anim handles only on refresh_all() and filepath
changes.
This commit and other commits attempting to fix it broke various things. The
main thing that changed was that instead of computing children/paths in
advance as part of particle_system_update, this was moved to do it just before
drawing or rendering. I've changed back that behavior and tried to keep the
other fixes in the commit.
When the new particle system was just committed, it also worked this way but
gave various problems, and I had to remove that behavior to get things working
stable. Basically it meant that you could get have a path cache that was
outdated in various situations, and it doesn't fit well with dependency graph
evaluation order.
This fixes:
#22823: Children Particle Rendering is broken
#22733: Particle objects not displayed
#22888: SigSegV when rending hair particles
#22820: Another SigSegV when undo adding hairs in particel edit mode
Some particle setups in dupligroups.
The three bugs that the original commit fixed are now also still working in
my tests:
#21316: Hair weight drawing is wrong
#21923: Consistent Crash When Rendering Particle Scene.
#21950: Path rendering option for particles causes crash
Fix#21187: 2.5svn26947 - particles + meta sphere = crash in rendering
Use separated displists for mballs in view3d and render stuff.
Do not recalculate displist for view3d while rendering - mball.c
uses several global variables which shouldn't be accepted from
parallel threads.
* Fractional frames support has been changed to use a new var, scene->r.subframe.
This is a 0.0-1.0 float representing a subframe interval, used in generating a final float
frame number to evaluate animation system etc.
* Changed frame_to_float() and some instances of bsystem_time() into a convenience function:
float BKE_curframe(scene) which retrieves the floating point current frame, after subframe
and frame length corrections.
* Removed blur_offs and field_offs globals. These are now stored in render, used to
generate a scene->r.subframe before render database processing.
by default now on all platforms since it shouldn't crash anymore if SSE is
not there. If this breaks compilation on some platforms, please let me know.
* Enabled premultiplication for packed images
* Added pack/unpack operator to image template
* Moved brightness/contrast corrections to after de-premultiplication in image texture sampling
- on instances last hit optimization was jumping to the last hit face
inside an instance without doing space transformation.
Fixed by making last hit optimization jump to the root node of the instance
instead of the last hit face.
* Path drawing now works for non hair particles.
* Should fix the following bugs too:
[#21316] Hair weight drawing is wrong
[#21923] Consistent Crash When Rendering Particle Scene.
[#21950] Path rendering option for particles causes crash
Now, rather than the bit-too-alarming stop sign, threaded wmJobs
display a progress indicator in the header. This is an optional feature
for each job type and still uses the same hardcoded ui template
(could use further work here...).
Currently implemented for:
Render - parts completed, then nodes comped
Compositor - nodes comped
Fluid Sim - frames simulated
Texture Bake - faces baked
Example: http://mke3.net/blender/devel/2.5/progress.mov
- fix implicit decloration of DAG_scene_sort()
- same fix for tiff as made in renderbranch
- rename 'combined peak' --> 'peak' for shorter messages while rendering.
* Take border render into account when drawing grid before for render
result becomes visible.
* Use antialiasing for rendering icon previews.
* Fix Full Sample not drawing render result while rendering.
* Mesh Deform Modifier: also forgot to commit this file.
* 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.
mask, also avoid making vertex groups if they will not be filled.
* Add back image pin option in image editor header.
* Fix deep shadow not respecting Cast Buffer Shadows option.
* Tangent space normal map baking should work again now.
* Fix a problem with particle duplis, due to own bugfix for #20350,
the problem for that seems to be in dupliverts, not particles.
* Fix external multires data link getting lost on exiting editmode.

if compositing, sequencer, fields, etc should be rendered, or if the
render does that itself. The weak point is that this only applies to
rendering, so if you open the compositor, it will still run on the
rendered result. Enabled by default, set to False to disable.
* Viewer node could free image while it is being redrawn, viewer image
buffers now need acquire/release to be accessed as was already the
case for render results.
* The Composite node could free the image buffers outside of a lock,
also causing simultaneous redraw to crash.
* Especially on Windows, re-rendering could crash when drawing an image
that was freed. When RE_RenderInProgress was true it would access the
image buffer and simply return it while it could still contain a pointer
to a render result buffer that was already freed. I don't understand
why this case was there in the first place, so I've removed it.
Possibly fixes bugs #20174, #21418, #21391, #21394.
