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

bd97c5e569 Fixed warnings in Bullet/src core library
Thanks Martijn Reuvers from Two Tribes B.V. (www.twotribes.com) for the patch

To make this work more visible, suppress warnings in external libraries in Extras (COLLADA_DOM, libxml and glui contain many warnings)
Added PreprocessorDefinitions: _CRT_SECURE_NO_DEPRECATE;_CRT_NONSTDC_NO_DEPRECATE to vcproj files

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.

d51c9f3247 second attempt to some pair management changes, allow to choose pair cache at run-time.
use btNullPairCache, btHashedOverlappingPairCache or btSortedOverlappingPairCache

56e072ccc6 fixed memory leak in btMultiSapBroadphase,
fixed hash function (typo, should use 2 proxies)
Thanks to Stephen (shatcher) for reporting and fixes!

ec76f2e0a3 - keep track of all memory allocations (gNumAllignedAllocs/gNumAllignedFree)
All memory allocations in Bullet go through btAlignedAlloc/btAlignedFree
Fix in hinge constraint constructors, thanks Marcus Hennix!

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)

52eb5fa1a4 don't use multisap yet in basic demo.
fix crash in multi sap (due to new pair manager)

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);
