1b70c4e5c9 added preliminary broadphase/collision C-API 2007-10-21 22:52:11 +00:00
ejcoumans
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

1e4e52306f don't crash when running out of pool memory, just use btAlignedAlloc/btAlignedFree instead 2007-10-19 21:25:58 +00:00

c625e756fe replaced btSimdMinMax.h by btMinMax.h in a few remaining places 2007-10-19 20:48:06 +00:00

6303d98844 - use mfc directly, instead of cellDmaSmallGet (allow sizes under 32 bytes, instead of 16) 
- align btBroadphaseProxy to 16 bytes
 2007-10-16 00:52:23 +00:00

23921729ea adding padding to broadphase proxy, to make it 16 bytes (helps some platforms to run) 2007-10-15 02:35:55 +00:00

ffcdb0f93d BulletMultiThreaded needs to refreshContactPoint for contact manifold (this has been moved to the collision detector, instead of constraint solver) 
BulletMultiThreaded support function for box shouldn't compensate for the collision margin anymore

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.

62103c94de fixed growing of hash table, to avoid hard limit on overlapping pairs 2007-10-12 05:53:27 +00:00
ejcoumans
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

23a197b3dc add alignment for broadphase proxy/handle. need to benchmark this, and check it doesn't degrade the performance on other platforms. Otherwise make it conditional only when USE_LIBSPE2 is defined 2007-10-03 00:41:55 +00:00

1d43b5ebae changed default stack size to 2 MB. This is still overly conservative probably. Need some deeper investigation on default memory sizes... 2007-09-30 04:43:34 +00:00

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);
 2007-09-08 05:40:01 +00:00
ejcoumans
30b1887f40 added configuration files for collision detection. 
this allows to use different collision algorithms by default, and avoid linkage issues.
