+ Allow user to enable useConvexConservativeDistanceUtil . Use dynamicsWorld->getDispatchInfo().m_useConvexConservativeDistanceUtil = true;
(see Demos/Benchmarks/Benchmark4 (convex objects falling down)
+ Fix for plane drawing (just wire-frame)
+ Gimpact: use collision margin of 0.07 for demo (because BULLET_TRIANGLE_COLLISION is used)
+ replace dot,cross,distance,angle,triple in btVector3 by btDot, btCross,btDistance,btAngle,btDistance to avoid naming conflicts
+ Some fixes in GJK penetration depth normal direction (broken in a previous commit)
+ fix in calculateDiffAxisAngleQuaternion to make ConvexConservativeDistanceUtil work properly
+ allow debug drawing to debug btContinuousConvexCollision
+ add comment/warning that btTriangleMesh::findOrAddVertex is an internal method, users should use addTriangle instead
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.
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
Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.
The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time
