Since rigid bodies need their world to be be updated correctly we now
pass it alongside the parent scene in scene_update_tagged_recursive().
Add BKE_object_handle_update_ex() as well as other object functions
that take a RigidBodyWorld for this.
Ideally this shouldn't be needed but we'd have to restructure scene
handling for that. It's not a small taks however and definitely not
something that can be done before release.
Thanks to Campbell for review.
Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!
With 2 windows, 2 scenes, linked objects:
- enter editmode in 1 window.
- the other window allowed to enter editmode too.
- and crash happened on exit editmode.
Since editmode is in Context (scene->obedit) a bad conflict arises.
New function BKE_object_is_in_editmode() returns this info outside of
context. Note I didn't use BMEdit_FromObject() because of the assert().
NOTE: contextual storage of editmode could need rework... five places:
- ob->mode / ob->restore_mode
- scene->object
- CTX_data_edit_object()
- BKE_object_is_in_editmode()
- view3d mode handling menu
Issue was caused by cycles being duplicated curve objects before converting
them to mesh. This duplication will loose pointcache which resulted in object
not being properly deformed.
fix pose-group-sort and pose-group-moving being disabled for pinned poses.
also fix for own missing NULL check for pose mask clear which would crash when run without an active object
* The operator creates bones for each input edge (does not subdivide
them like the skin operator does), adds a fake root bone for skin
roots with multiple children.
* The operator adds vertex weight groups to the original mesh.
* Make copy_object_transform() public, used to match the armature
object to the mesh object.

Most of the changes are related to adding support for motion data throughout
the code. There's some code for actual camera/object motion blur raytracing
but it's unfinished (it badly slows down the raytracing kernel even when the
option is turned off), so that code it disabled still.
Motion vector export from Blender tries to avoid computing derived meshes
when the mesh does not have a deforming modifier, and it also won't store
motion vectors for every vertex if only the object or camera is moving.
Was missed check for if modifier is available for particular object type
which ended up with unpredictable results when modifier which isn't supported
yet for some object type as linked to that object type.
added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count
added object_tfm_protected_backup, object_tfm_protected_restore so its easier to transform the object and respect protected channels (otherwise you need checks everywhere for each channel which is verbose).
===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.
More details about this project can be found on this page:
http://wiki.blender.org/index.php/User:Nazg-gul/GSoC-2011
Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
duplicate of BKE_curframe() which just takes two extra args.
For the few calls in the physics engine where CFRA+1 instead of CFRA
was being used, I've added a new BKE_nextframe() call, which will
calculate for CFRA+1 instead of CFRA in much the same way that
bsystem_time() would end up doing things (which means including
subframe steps).
incompatible, and unmaintainable Time Offset cruft.
- Slow Parenting lives another day (just), although it now carries
appropriate cautionary disclaimers. It's only really for the Game
Engine nowadays, as that's the only place where it can possibly work
with any reliability.
- "Animation Hacks" panel is now "Relations Extras". I could've merged
the two panels, though I figured these options weren't that frequently
used to justify taking up screen-space by default along with the panel
- Added support of variable size sensor width and height.
- Added presets for most common cameras, also new presets can be defined by user.
- Added option to control which dimension (vertical or horizontal) of sensor
size defines FOV. Old behavior of automatic FOV calculation is also kept.
- Renderer, viewport, game engine and collada importer/exporter should
deal fine with this changes. Other exporters would be updated soon.
vecs = Camera.view_frame(scene)
returns 4 points for the camera frame, without this its very hard to know if a point is in the camera view or not, without rewriting blenders internal logic in python.
- making local object data - Curve/Mesh/MBall lost references to linked materials.
- joining a linked mesh object into a local one lost the link.
As well as these reported bugs, checked all local functions for consistency/correctness and found other cases which would also fail.
- making local metaball didn't ensure unique ID name.
- make_local_armature() was missing check for object users - main body of code would never run.
- local particles didn't set the dupli-group or textures to extern.
checked all local functions for consistency/correctness.
- render check for ortho/panorama combination wasn't working since the flags were not initialized at the time of checking.
- disable panorama button in ortho mode.
Object.is_modified(scene, 'PREVIEW') function for python exporters to check if any modifiers or shape keys are applied (weather the original mesh can be used for exporters).
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
- object updates were not being flushed, so children weren't updating.
- apply the matrix relative to the parent, added this as an option to object_apply_mat4() which allows assigning the worldspace matrix in python without worrying about the parent.
- 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.
