c80d1532f6 made access to mesh interface more consistent, so btConvexTriangleMeshShape uses also 'getMeshInterface', similar to btTriangleMeshShape.
Thanks Et3D for pointing this out here: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1590

e7caaa28d3 re-organized memory (stack and pool) allocators. this lets the user pass in their own memory allocators. 2007-10-20 02:23:39 +00:00

ea3dfb4ca3 made 'calculateLocalInertia' const, thanks to cgripeos, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1514
- 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.

eff4fe8ec8 more work on hashed pairmanager. growing doesn't work yet, so need to allocate enough room for the overlapping pairs in advance.
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)

0405ce278a use size_t instead of int, for allocator
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

a38de566c6 make sure aligned structures/classes use the btAlignedAlloc/btAlignedFree, by overriding the operator new/delete for that struct/class.

b054f375bc - Added serialization to btBvhTriangleMeshShape/btOptimizedBvh. See ConcaveDemo for example usage.
- 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

87df3d0f32 Based on feedback from another professional game company, there are several improvements, including some API change...
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);

1f7646f72a Refactoring to enable multi SAP broadphase.
This was already planned, and Pierre Terdiman recent thread motivated me to decouple the paircache from the sweep and prune.

685138d033 include paths should not be relative starting with "../
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.

cf2337ed7b - Fixed a bug in btAxisSweep3 (sweep and prune) related to object removal. Only showed up when at least one btStaticPlaneShape was inserted.
Thanks tbp for more details on reproducing case.
- Fixed issue with full 32bit integers in btAxisSweep3 (define BP_USE_FIXEDPOINT_INT_32), it used only 65536 for quantization, it should use full integer space (0xffffffff)
- Added 'getForwardVector' and getCurrentSpeedKmHour utility functions to btRaycastVehicle
- Fixed local scaling issues (btConvexTriangleMeshShape, btBvhTriangleMeshShape, removed scaling from btMatrix3x3). Thanks Volker for reporting!
- Added second filename search, so that starting BspDemo and ConvexDecompositionDemo from within Visual Studio (without setting the starting path) still works

Added braking capability to btRaycastVehicle, see Bullet/Demos/VehicleDemo/VehicleDemo.cpp
Added glutKeyboardUpFunc, for vehicle demo (keep accelerating/breaking, until key released/UP). Hope this is compatible with most GLUT implementations.
