c782f4976c Various minor PLBVH related changes.
-Use most significant bit instead of negative for internal nodes.
-Explicitly store root node index, so that it does not have to be 0.
-Check the root node first in PLBVH traversal.
-Fix rigid body clipping in RaytracedShadowDemo.

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)

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
add missing bullet.pc.cmake file (for old Bullet 2.x)

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)

Same for b3InertiaCL -> b3InertiaData
