Was polluting compile output too much.
|
|
I tried to carefully preserve all patches since the last upgrade.
Improves T47195, cloth collision detection bug.
Differential Revision: https://developer.blender.org/D1739
|
|
Also add depsgraph & physics
|
|
Fixes part of T37905, fixed constraint didn't work correctly.
|
|
Remove patch that has been applied upstream.
Fixes several bugs.
|
|
Apply patches in patches directory, remove patches that were applied
upstream.
If you made changes without adding a patch, please check.
Fixes [#32233] exporting bullet format results in corrupt files.
|
|
Remove Jamfiles and other unused files that stuck around during previous updates.
Add patches for local changes to the patches directory.
Update readme.txt, it had outdated infromation.
|
|
|
|
add PhysicsConstraints.exportBulletFile(char* fileName) python command
I'll be checking the bf-committers mailing list, in case this commit broke stuff
scons needs to be updated, I'll do that in a second.

fixes around license blocks

modifications to Bullet have been reported to Bullet forum. Note: welding is completely disabled on soft body as it breaks the relationship between the soft body collision shape and the graphics mesh without bringing any additional stability (the reverse actually).
|
|
The cause of this is in the bullet library, seems like some kind
of poor handling of many repeated allocations by Mac OS X, but the
allocation is unnecessary, so removed it.
Patch submitted to bullet:

fixed before Blender 2.49.
In particular, the Bullet vehicle seems broken, and some soft-body demos don't work.
No new features or benefits are added yet, but a few improvements are planned before Blender 2.49 release.
Please update the build systems, and add those 3 files:
extern/bullet2/src/BulletCollision/CollisionDispatch/btActivatingCollisionAlgorithm.cpp
extern/bullet2/src/BulletCollision/CollisionDispatch/btGhostObject.cpp
extern/bullet2/src/BulletCollision/CollisionShapes/btConvexPointCloudShape.cpp
I'll watch the Blender mailing list, in case this commit causes some issues.

objects

1) re-allocate a pool allocator, if one of the soft body collision algorithms is larger than max pool element size
2) manage child shapes properly, and call RemoveReferences on the m_sparsesdf
|
|
Bullet logic bug in (de)activation/island management: deactivated 'fantom' objects do merge islands, in particular when connected by constraints. (fantom = object with collision detection but no collision response).
|
|
hooking up / deform graphics mesh and choose collision shape.
Note: feature is still disabled.
|
|
removed/refreshed.

btSoftBody, and better fix for 64-bit issue in btCompoundCollisionAlgorithm.
|
|
This should be harmless/non-intrusive.
Please make sure each build system include extern/bullet2/src/BulletSoftBody/* and extern/bullet2/src/LinearMath/btConvexHull.*

(except for one define 'WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER')
In case someone reads those SVN logs: you can enable some extra broadphase SSE optimizations by replacing WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER by WIN32 in extern/bullet2/src/BulletCollision/BroadphaseCollision/btDbvt.h
Thanks to Benoit Bolsee for the upstream patch/contribution.
Removed some obsolete files, they were just intended for comparison/testing.
|

tracker for inclusion in later revision. If it is not included, apply manually extern/bullet2/bullet_compound_raycast.patch
|
|
recent changes in extern/bullet2 need to be re-applied, will check with Benoit. Ray tests in 0_FPS_Template.blend is broken, didn't figure out why yet.
HELP BUILD SYSTEM MAINTAINERS: Please help with updating all build systems: the newly added files need to be added. Note that the src/SoftBody has been added for future extension of real-time soft bodies.

information and broad phase filter. This patch is needed to support enhanced ray cast function in the BGE. I have proposed it to the Bullet forum for inclusion in the next Bullet version.

island activation issue
|

Please make sure to have extern/bullet/src/LinearMath/btAlignedAllocator.cpp in your build, if you add the files by name, instead of wildcard *.cpp

finished yet, and GameBlender is still using extern/bullet.
|
|
the Blender build yet. First, the integration will be updated to make use of the new Bullet version. Then all build systems needs to be updated.
The refactoring didn't leave a single file the same, all filenames and classes have bt prefix, methodnames start with lowercase, a single headerfile can be included, and also a single include path.
Plan is to make use of this Bullet 2.x version in extern/bullet2 within the coming weeks, then extern/bullet can be discarded/ignored/content removed.
