badf723257 Replace all hardcoded 1e30(f) by BT_LARGE_FLOAT, defined in btScalar.h as 1e18(f) so that its square still fits in FLT_MAX
Thanks to Ole K. for reporting! http://code.google.com/p/bullet/issues/detail?id=206

8acadeb711 minor tweaks to demos: enable constraint debug drawing in AllBulletDemos, default constraint debugging size set to 0.3,
set svn:eol-style native for folder files

2a10a61f50 Some work-in-progress on making btDbvtBroadphase deterministic. When using the btSortedOverlappingPairCache, it seems deterministic now. todo: when using btHashedOverlappingPairCache. 2009-02-10 03:50:58 +00:00

50344c4a23 Add support for broadphase acceleration of convex cast (re-use rayTest implementation with an added aabb min/max, zero for rays)
Add Concave Convexcast demo back in AllBulletDemos, and tweaked it a bit.
Fix view frustum of ForkLiftDemo (caused picking to fail)
Removed innerloop profiling for ray and convex casts, it hurts performance.
Set default #aabb's in CDTestFramework to 8192

fffca75e9f Make raycast benchmark default, to show improved raycasting performance.
Add rayTest to btBroadphaseInterface, and implement efficient version for btDbvtBroadphase to accelerate raycasting.
btAxisSweep3, btSimpleBroadphase and btMultiSapBroadphase implement brute-force method (as before). For now, it is recommended to use btDbvtBroadphase for fastest world raycast.

9ad17dda22 Add aabbMin/aabbMax to broadphase proxy, and improve rayTest performance.
Todo: use broadphase acceleration structure (btDbvtBroadphase etc) for ray test

79b6f7a772 Removed (circular) dependency between broadphase and collision shapes: moved parts CollisionShapes/btOptimizedBvh into BroadphaseCollision/btQuantizedBvh 2008-08-26 23:40:51 +00:00

884a494412 make the source code compile with older compilers again (Visual Studio 2006 in particular)
renamed btDbvt::Volume to btDbvtVolume and btDbvt::Node to btDbvtNode to distinguish from btSoftBody::Node

bb680f512d avoid warning of passing the 'this' pointer into constructor 2008-03-18 05:20:39 +00:00

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.

44186898af Got btMultiSapBroadphase in a working state. Now tuning/optimizations can be started.
Added getBroadphaseAabb to btBroadphaseInterface.

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.
integrated some contributions from IBM Germany for libspe2

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);
