- Using correct frame to update particle system tree for SPH simulation (i.e. psys_update_particle_bvhtree(psys, cfra)).
- Increased SPH neighbour count to 512 - this greatly reduces BVH tree search bias, and makes simulations more symmetrical.
Adaptive time step improvements:
- Fix for relative velocities based on previous state (fixes fast-moving particle clusters).
- Only reporting on element size once per time step. Prevents incorrect Courant number from being calculated when using multiple-step integration.
bvhtree_ray_tri_intersection now using isect_ray_tri_epsilon_v3 with FLT_EPSILON. All devs I asked (incuding ones in physics/painting areas) were rather OK with this change, and better to do it now, with more than one month to detect regressions, if any!
* Fix: Smudge and brush velocity settings didn't work for "image sequence" surfaces unless any paint effect was enabled.
* Adjusted some property ranges.
This commits merges object tracking implementation from tomato branch.
Summarized changes from branch:
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- Object has got scale to define "depth" in camera space.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.
- Improvements in witness cameras workflow,
For premultiplied alpha images, this makes any color space conversion for the image
or render output work on color without alpha multiplied in.
This is typically useful to avoid fringing when the image was or will be composited
over a light background. If the image will be composited over a black background on
the other hand, leaving this option off will give correct results.
In an ideal world, there should never be any color space conversion on images with
alpha, since it's undefined what to do then, but in practice it's useful to have
this option.
Patch by Troy Sobotka, with changes by me.
- Enable bicybic filtering fir image displayed in track preview
- Option to show grayscale content of track preview
- When some channels are disabled, display exactly the same
content of preview image which is sending to tracker library.

* this loop is called multiple times per vertex (not addressed in this commit)
* functions like brush_use_size_pressure(), brush_use_size_pressure() called unified_settings() twice when they didnt need to.
looks like this code cant work right with multiple scenes, added a comment on this - but at least avoid calling unified_settings() multiple times in single functions.
byte => float, float => float, byte => byte conversions with profile, dither
and predivide. Previously code for this was spread out too much.
There should be no functional changes, this is so the predivide/table/dither
patches can work correctly.
Use proper timecode flags sending to BKE_movieclip_get_ibuf_flag function,
so now frames for tracking would be full-resolution but calculated using
timecode defined in th interface,
Also, allow applying to obdata those modifiers, even with shapekeys, but do not allow applying them *as* shapekey (as shapekeys do not have CD layers).
Fix [#29636] Vertex Weight Mix modifier "apply" button don't work.
Note: applying whit shape keys currently always uses base shape, not current one (for apply to obdata as well as apply to shapekey), but this is another topic...
