Note that BulletFileLoader is has no dependencies on BulletDynamics/BulletCollision.
Also added a custom build step to copy asset (.bullet and .obj file) into the executable folder
Made a few 'char*' 'const char*' to avoid compiler warnings
Constraints reworked - all of them could now work with one or two bodies
Modification of constraint frames and initial positions of rigid bodies
now allowed at start frame only
Plugin version is set to 2.76
Thanks SkewMatrix for the patch
Fix a crash in BulletColladaConverter, when bodies were created outside of the Collada converter,
Thanks Jan Ciger for the patch, see Issue 306
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)
Fix for btConvexConvexAlgorithm, potential division by zero
Thanks linzner http://code.google.com/p/bullet/issues/detail?id=260
1) use $(CUDA_INC_PATH) for CUDA include path
2) avoid using cuda util, but use BT_GPU_SAFE_CALL and BT_GPU_CHECK_ERROR (defined in Bullet/Extras/CUDA/btCudaUtil.h)
3) remove pre-linked glee*.lib, but include glee.c directly
4) removed fluids_2008.sln, just use automatic converted upgrade using fluids_2005.sln solution
Use Bullet/Glut/GL folder, instead of Bullet/Extras/spu/common/GL folder)
It is disabled by default, see Demos/Gpu2dDemo/btGpuDemoDynamicsWorld.h for instructions how to enable it
Cleaned up Extras/CUDA folder and libbulletcuda project

We plan to integrate the SPH into the core Bullet library, including interaction with rigid bodies and soft bodies.
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
body->setLinearFactor(btVector3(1,0,1));
body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.
Usage: set RayResultCallback.m_flags to kF_FilterBackfaces, optionally combined with kF_KeepUnflippedNormal.
Thanks Andy O'Neil for the patch!
Remove the force_inline for some internal constraint solver methods, it makes re-use easier.
Workaround/avoid MSVC 2005 compiler error in LibXML/trionan.c
improve CollisionDemo.cpp, show multi-contact generation using perturbation
improve ColladaConverter: add hinge/point 2 point constraint conversion support, add btScaledTriangleMeshShape support
Fix Dynamica MayaPlygin: remove 'active' flag, it has to be replaced by mass=0 for active, mass<>0 for passive
Added missing projectfiles
Fixed single-shot contact generation. it is disabled by default to improve performance
Bugfixes for character controller, thanks to John McCutchan for reporting
Constraint solver: better default settings
btDefaultAllocator: aligned allocator uses non-aligned allocator (instead of directly malloc/free)
disable memalign by default, use Bullet's aligned allocator
Note: ColladaConverter will export a btGImpactConvexDecompositionShape the same as a btCompoundShape, so importing an exported btGImpactConvexDecompositionShape (roundtrip) creates a btCompoundShape
1) Add fast branchless SIMD support for constraint solver (Windows only until we get other contributions).
See resolveSingleConstraintRowGenericSIMD in Bullet/src/BulletDynamics/ConstraintSolver/btSequentialImpulseConstraintSolver.cpp
resolveSingleConstraintRowGenericSIMD can be used for all constraints, including contact, point 2 point, hinge, generic etc.
2) During this refactoring, all constraints support the obsolete 'solveConstraintObsolete' while we add 'getInfo1' and 'getInfo2' support.
This interface is almost identical interface to Open Dynamics Engine, to make it easier to port Dantzig LCP solver.
3) Some minor refactoring to reduce huge constructor overhead in math classes.
It is called bt3DGridBroadphase and btCudaBroadphase is now derived from it rater than from btSimpleBroadphase
Test of bt3DGridBroadphase was added to CDTestFramework
Add Concave Convexcast demo back in AllBulletDemos, and tweaked it a bit.
Fix view frustum of ForkLiftDemo (caused picking to fail)
Removed innerloop profiling for ray and convex casts, it hurts performance.
Set default #aabb's in CDTestFramework to 8192
See USE_SOFTWARE_CACHE in Bullet\src\BulletMultiThreaded\SpuNarrowPhaseCollisionTask\SpuGatheringCollisionTask.cpp
It improves the Bullet midphase collision detection (triangle/vertex fetch)
The license is CommonPublicLicense-1.0, see included license docs.
Some cleanup for ForkLiftDemo
Enable textures for ConcavePhysicsDemo,
Added scaling to BasicDemo to show small objects (20 centimeter)
Removed demos from 'AllBulletDemos': less (clutter) = more
Fix issues with btDbvt: use ATTRIBUTE_ALIGNED16
Removed several places where variable was declared within for statement: for (int i=0; should be int i; for (i=0
Disable libxml LIBXML_MODULE_EXTENSION
Fixed include path in btConeTwistConstraint (it should be relative to src folder, not using ../../ )
Thanks to ejtttje, http://code.google.com/p/bullet/issues/detail?id=129
Don't create a todo list for doxygen by default (the chaotic todo's would confuse most developers)
Improve support for small objects, by having dynamic contact breaking thresholds. Still needs small internal timestep and some GJK improvements.
Fixed recently introduced issue: can't re-use stack as member variable (to reduce memory allocs) in btDbvt, due to recursion.
remove btGjkEpa.* from Makefile.am, Makefile and CMakeLists.txt
avoid division-by-zero in ODE boxbox contact reduction
Plan is to convert COLLADA XML into IFF, for faster, more compact and easier to read and parse files.
Reading/writing code is a few hundred lines of code, instead of COLLADA-DOM and libxml combo.
So it would be suitable as a run-time format for platforms ranging from iPhone to PlayStation 3.
Relevant physics data (and perhaps other data) will be converted from COLLADA -> IFF.
We could call the resulting files COLLADA binary IFF -> CLIFF.
