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

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

08d036afc7 multi-threading improvements: optionally use software caching (IBM/PS3), move some code from cpp to header to inline. 2007-09-20 22:42:56 +00:00

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);

b43b8f0f75 - added 'init' function for DoubleBuffer, in case constructor is not called. 
- use proper transform for concave case

f19bc68408 fixed Win32 Threaded, by waiting for multiple objects (it was re-using the same task all the time)

ec22825e65 added parallel solver (work in progress) and made modifications to demo/constraints to allow for getting the type without using virtual functions (needed on CELL SPU processors) 2007-08-12 17:27:33 +00:00

5279f9e129 BulletMultiThreaded (SPU/multi-core): added compound shape support and concave-convex (swapped case). Thanks to Marten Svanfeldt 2007-08-02 20:16:58 +00:00

38b7f474c3 Added better support for btUniformScalingShape, by moving some data that is not shared from btConvexShape to btConvexInternalShape. This reduces the sizeof btUniformScalingShape to 16 bytes (from 64). 
This is good when having lots of re-used shapes with different sizes.

Convex shapes will need to derive from btConvexInternalShape (which is a subclass of btConvexShape). We could have renamed btConvexShape to 'btConvexShapeInterface' (can still do that later)

121fd7808e Changed BulletMultiThreaded Thread Support to be passed in, rather then global 'Win32ThreadSupport'/'Libspe2ThreadSupport' etc. 
This allows developer to hookup Bullet to a custom task scheduler, by deriving from btThreadSupportInterface.

6f26aa1591 Added multi-threaded collision detection. Original code is written for Cell SPU, but wrappers are provided to run on multi-core using Win32 Threads. 
SpuLibspe2Support is on the todo list, so it can run on Cell Blade & PS3 Linux.
