e6c850f13b Fix/improve raycast performance for btBvhTriangleMeshShape (btQuantizedBvh, btOptimizedBvh)
Add raycast acceleration for btAxisSweep3, using btDbvtBroadphase, providing large speedup. Can be disabled in constructor to safe memory.

d7b635cabf logic bug in (de)activation/island management: deactivated 'fantom' objects do merge islands, in particular when connected by constraints. (fantom = object with collision detection but no collision response). 2008-09-23 04:57:20 +00:00

60fa900995 Added CCD motion camping, to avoid tunneling.
Not as versatile compared to btContinuousDynamicsWorld but still useful.

f8e5481612 Added method to collect all persistent contact manifolds, given a btBroadphasePair (collision algorithm)
virtual	void	getAllContactManifolds(btManifoldArray&	manifoldArray)
See Demos/CharacterDemo/CharacterDemo.cpp for example usage of getAllContactManifolds

Enable soft body vs concave (albeit slow)
Improved contact point debug rendering (moved from constraint solver into debugDrawWorld)

65bb612598 - added quickSort to btAlignedObjectArray (has generally better performance then heapSort)
- 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.

f12f04fb97 optimization: only call solveGroup if there is some work: avoid virtual function call, its overhead can be excessive

d051e2eacb First commit of 2008, Happy New Year!
Add option to compile without btClock and without profiling: comment out USE_BT_CLOCK, and #define BT_NO_PROFILE
Fixed typo/case in #include "LinearMath/btQuickProf.h", in SpuParallelSolver.cpp
Removed unnecessary files from libxml CMakeLists.txt

17a214a2b3 - Added btRigidBodyConstructionInfo, to make it easier to set individual setting (and leave other untouched) during rigid body construction.
This was harder using default arguments. Thanks Vangelis Kokkevis for pointing this out.
- Fixed memoryleak in the ConstraintDemo and Raytracer demo.
- fixed issue with clearing forces/gravity at the end of the stepSimulation, instead of during internalSingleStepSimulation.
Thanks chunky for pointing this out: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1780
- Disabled additional damping in rigid body by default, but enable it in most demos. Set btRigidBodyConstructionInfo m_additionalDamping to true to enable this.
- Removed obsolete QUICKPROF BEGIN/END_PROFILE, and enabled BT_PROFILE. Profiling is enabled by default (see Bullet/Demos/OpenGL/DemoApplication.cpp how to use this).
User can switch off profiling by enabling define BT_NO_PROFILE in Bullet/src/btQuickprof.h.

947dc8d33d Moved the 'btRigidBody::clearForce' to the end of the stepSimulation, instead of in each substep.
Should help with this issue, reported here: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1601
We can optionally leave out the 'clearForces'.
Thanks everyone for the discussion.

a101719687 - removed warnings in GLUI, thanks Jorrit Tyberghein for the patch!

ec76f2e0a3 - keep track of all memory allocations (gNumAllignedAllocs/gNumAllignedFree)

c80d1532f6 made access to mesh interface more consistent, so btConvexTriangleMeshShape uses also 'getMeshInterface', similar to btTriangleMeshShape.

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

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.

054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal).
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015
