Thanks Martijn Reuvers from Two Tribes B.V. (www.twotribes.com) for the patch
To make this work more visible, suppress warnings in external libraries in Extras (COLLADA_DOM, libxml and glui contain many warnings)
Added PreprocessorDefinitions: _CRT_SECURE_NO_DEPRECATE;_CRT_NONSTDC_NO_DEPRECATE to vcproj files
+ fix related btMinkowskiSumShape issue in btSubsimplexConvexCast and btGjkConvexCast
+ add hitpoint for btSubsimplexConvexCast
+ reduce maximum number of iterations in conservative advancement/CCD implementations
Added very basic drawTriangle for btIDebugDraw, useful for basic softbody visualization.
Added btGjkEpa2, contribution by Nathanael Presson. Improved version of EPA penetration depth computation, more suitable for multi-core/SPU (less memory usage). Note: btGjkEpa2 is not enabled by default currently.
- replaced all usage of heapSort by quickSort
- finished btMultiSapBroadphase. Still some work to be done to increase performance (faster add/remove from child broadphases.
uses currently AABB tree to locate child broadphase (should use grid), and sorted array takes too much time.
- copy user data over to child shape
- added applied impulse to btManifoldPoint
- add ContactProcessedCallback (needs test/demo)
- didn't copy over m_additionalDampingFactor into btRigidBody.
- applied a large patch to remove warnings
Thanks to Enrico, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1568
- removed SSE includes, added #incude <string.h> for memset in Extras/quickstep, thanks Eternl Knight
- disabled 16-byte alignement on btQuadWord class, it causes problems under PS3 Linux. Need to check out why.
added hashtable based PairManager, thanks Pierre Terdiman and Erin Catto
improved friction in 'cachefriendly' solver
moved 'refreshcontactpoints' into collision detection, instead of solver
avoid linear search for contact manifolds, by storing an index
ignore margin for sphere shape (its entire radius is already margin)
avoid alignment checks in BVH serialization, they don't compile on 64-bit architectures
made 'bomb' box more heavy
Some dynamic memory allocations have been replace by pool allocation or stack allocations.
quantized aabb versus quantized aabb overlap check is made branch-free (helps a lot on consoles PS3/XBox 360)
Collision algorithms are now created through a new btDefaultCollisionConfiguration, to decouple dependency (this is the API change):
Example:
btDefaultCollisionConfiguration* collisionConfiguration = new btDefaultCollisionConfiguration();
m_dispatcher = new btCollisionDispatcher(collisionConfiguration);
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.
Keep include path starting with "LinearMath/, "BulletCollision/, or "BulletDynamics/
Added btStackAlloc to Bullet (right now only used by btGjkEpa)
removed default constructors of btCollisionWorld/btDiscreteDynamicsWorld, to reduce link-time dependencies
