boxbox reports contact point in B, rather then average point
box, cylinder use halfextents corrected for scaling and margin. made the margin in this halfextents explicit in the 'getHalfExtentsWithMargin' and 'getHalfExtentsWithoutMargin'
integrated changed for ODE quickstep solver
replaced inline with SIMD_FORCE_INLINE
some minor optimizations in the btSequentialImpulseConstraintSolver
added cone drawing (for X,Y,Z cones)
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
added preliminary continuous dynamics world (under construction, not ready yet)
fix crash on when restarting simplex demo using spacebar, Thanks Jorrit Tyberghein for reporting!
- added bt32BitAxisSweep3, which co-exists without recompilation, using template class. This broadphase is recommended for large worlds with many objects (> 16384), until btMultiSwap is finished.
- Fixed some recent issues in Bullet 2.57 related to compound (thanks Proctoid) and memory allocations
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);
This is good when having lots of re-used shapes with different sizes.
Convex shapes will need to derive from btConvexInternalShape (which is a subclass of btConvexShape). We could have renamed btConvexShape to 'btConvexShapeInterface' (can still do that later)
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/
support user-defined broadphase collision filtering (thanks Marten)
make sure btSimpeDynamicsWorld doesn't use cache friendly optimization in the solver (added an assert, and updated BasicDemo)
