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:
http://code.google.com/p/bullet/issues/detail?id=303
* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
* ensure all SConscripts are ready for win64-vc (where necessary).
* ensure we have proper _DEBUG flag for Python when we're doing a debug build.
* some cleaning up of linking etc.
* ensure /EHsc is there for game engine modules.
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
- added missing files
- cleanup of some project settings
- RNA building has dependency issue: had to add interface_api.c to the makesrna project and makesrna and rna projects now include editors.
- added debug libraries for OpenExr, please update lib/windows/openexr to get them
This commit contains a number of performance improvements for the
BGE in the Scenegraph (parent relation between objects in the
scene) and view frustrum culling.
The scenegraph improvement consists in avoiding position update
if the object has not moved since last update and the removal
of redundant updates and synchronization with the physics engine.
The view frustrum culling improvement consists in using the DBVT
broadphase facility of Bullet to build a tree of graphical objects
in the scene. The elements of the tree are Aabb boxes (Aligned
Axis Bounding Boxes) enclosing the objects. This provides good
precision in closed and opened scenes. This new culling system
is enabled by default but just in case, it can be disabled with
a button in the World settings. There is no do_version in this
commit but it will be added before the 2.49 release. For now you
must manually enable the DBVT culling option in World settings
when you open an old file.
The above improvements speed up scenegraph and culling up to 5x.
However, this performance improvement is only visible when
you have hundreds or thousands of objects.
The main interest of the DBVT tree is to allow easy occlusion
culling and automatic LOD system. This will be the object of further
improvements.
Notes:
* Sequence transform strip uses G.scene global, this is commented
out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
2.5 got merged, but no new files were added. Calls to these files
are commented out with "XXX etch-a-ton". editarmature.c and
transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
(player still fails to link).
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.
* add preliminary support for building Blender on 64bit Windows with _msvc_. The SConstruct should automatically detect if you are on a 64bit Windows and if you have that 64bit build is assumed. If you're not, 32bit build is assumed.
NOTE: this is still very much wip, so your mileage may vary. Do please report on b25 taskforce ML in case of trouble.
NOTE2: many of the libs are being linked in statically
NOTE3: hopefully I didn't break anything for other build platforms (mingw, linux, osx).
NOTE4: comes after NOTE3
* giving compileflags, cc_compileflags and cxx_compileflags to BlenderLib() now actually overrides any other setting (so there's no unclarity when ie. conflicting options are being specified in REL_CFLAGS et al). These are set after either release or debug flags, but before any *_WARN flags (so those stay maintained).
* add cxx_compileflags for GE parts on win32-vc to have better performance.
* NOTE: if platform maintainers (OSX and Linux) could check and do the same for their systems. Not vital, but probably very, very much welcomed by GE users.
I did a very drastic cleanup for the different libgroups, there's now only a few left. It compiled with scons/msvc, will be testing in a bit on linux, too.
If you get any problems, please reply to this commit message on the taskforce ML.
Enable soft body collision clusters by default.
Add option to 'disable collision' button between soft body and rigid body connected by constraint (option was already available between two rigid bodies)
#if defined (__sun) || defined (__sun__) || defined (__sparc) || (defined (__APPLE__) && ! defined (__i386__))
Also includes a fix to uninitialized variable (can cause failing collisions).
If possible, report all changes to extern/bullet2 to http://code.google.com/p/bullet/issues/list
I changed sqrtf to sqrt in elbeem
in bullet2 I added defines found in floatpatch.h eventually
we should make a "floatpatch.h" that all of blender can use.
Kent
and noticed dos line endings in a bunch of files so ran
dos2unix on everything in bullet2.
Erwin, I noticed there are a few files that do not have
license info in them, couple of quick examples are: btDefaultMotionState.h
btHashMap.h btQuickprof.cpp
could you take a look at add where needed? If you want I can give a list
of files I think should get it added and or just add the standard one
say the one in src/btBulletCollisionCommon.h
Kent
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
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)
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).
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.
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.
- fix for 3DPlugin compile
- cleanup of bullet path
- removed PHY_ODE project from 3D plugin too, not used anymore
Now all configurations should build again, let me know of any problems!
Not been able to test if the 3DPlugin is actually working,is job for another day ;)
Also the 3DPlugin is compiled without OpenExr, this needs to be looked into once too.
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.
