122ceacb6d move OpenCL initialization for the unit tests in a shared header file, and support some basic command-line arguments 
--cl_device=1 --cl_platform=1 --allow_opencl_cpu
add chaindemo, test for mass ratios
restore sleeping/activation mode in featherstone demo
Use _VARIADIC_MAX=10 to avoid Google Test issues with Visual Studio 2012, thanks to Mobeen for the report
Enable verbose printf for unit tests

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)

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

6142bdca0a brDefaultMotionState::getWorldTransform was wrong, in case of a non-identity centerOfMassOffset.

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)

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
