3e8b183587 Avoid breaking up the clipHullHull kernel, it ruins performance. Unfortunately, Mac OSX still requires it. 
Use indices instead of copies for small/large aabbs in broadphase (grid / sap)

ff051f87aa replace 'copy' step of large/small Aabbs by indices 2014-01-29 12:52:31 -08:00

33ebebd1c9 allow PairBenchmark to select broadphase type, with cpu brute-force, gpu brute-force etc 
fix issue in PairBench, related to index offset
allow to add a large AABB in PairBench, to see the effect on the broadphase pair search performance

71f0537c6e add Bullet 2.x constraint solver tests for hinge, with large mass ratio 
experiment with Midi controls in PairBenchmark to tune variables (will move it into a utility class, so every demo can easier use it in the future)
fix issue with broadphase, not initializing all pairs properly at pair array overflow

7cdda65822 Experimenting with GUI in PairBench, still preliminary. Goal is to make it easier to add variables that can be tuned using GUI/gwen

f14ec7b870 split the unitsphere search in a separate kernel, m_findSeparatingAxisUnitSphereKernel, hopefully it works on Mac OSX OpenCL now. 2014-01-16 14:19:43 -08:00

472a4068fc Enable MPR by default 
Add the contact point from MPR, in addition to SAT/clipping contacts. Added a new kernel to clear/reset the number of contacts in pairs (stored in the z component)
Always sample unit sphere directions, if there are more edge-edge combinations than unit sphere directions (162 by default)
Remember last running demo for Bullet 3 (and save it in a text file, Bullet
Enable the testFileFracture.bullet in the Bullet2FileDemo

2e55d03fd9 more fixes towards working convex-convex, in case of (too) many edge-edge cases: 
1) sample directions over a unit sphere and
2) add a contact, using mpr

271f458837 Ported Minkowski Portal Refinement mpr.c from libccd to OpenCL, for bettwe edge-edge performance (and additional contact point for degenerate/high detailed convex shapes) 
Removed b3RigidBodyCL, replace by b3RigidBodyData and b3RigidBodyData_t shared between C++ host and OpenCL,
Same for b3InertiaCL -> b3InertiaData

a78cbcf354 Accidently left some very slow copyToHost in the batching code, removing it makes it faster :-) 2013-11-12 09:03:30 -08:00

5ce0b3938f Re-introduce GPU parallel Jacobi solver, called btGpuJacobiContactSolver. There are still some issues, but for basic scene's it works. 
To avoid confusion, rename GPU contact solver to btGpuContactSolver, and constraint (non-contact) solver to btPgsConstraintSolver.

677722bba3 support compound versus compound collision shape acceleration on GPU, using aabb tree versus aabb tree. 
Remove constructor from b3Vector3,  to make it a POD type, so it can go into a union (and more compatible with OpenCL float4)
Use b3MakeVector3 instead of constructor
Share some code between C++ and GPU in a shared file: see b3TransformAabb2 in src/Bullet3Collision/BroadPhaseCollision/shared/b3Aabb.h
Improve PairBench a bit, show timings and #overlapping pairs.
Increase shadowmap default size to 8192x8192 (hope the GPU supports it)
