remove duplicate data in b3Contact4 (now in btContact4Data shared between CPU/C++ and OpenCL)
OpenCL kernels use #include "Bullet3Collision/NarrowPhaseCollision/shared/b3Contact4Data.h"
Increase number of batches back to 250 (from 50), need to fix this hard coded number (see https://github.com/erwincoumans/bullet3/issues/12)
Work towards GJK/EPA, in addition to SAT/clipping (early on)
and embed the included files directly in the stringified files.
We need this, because we start sharing struct definitions and code between C/C++ and OpenCL (and potentially other languages)
preprocessor is from http://github.com/willsteel/lcpp
added tetrahedral mesh test scene
expose b3Config as member variable for demos.
move a 'glFlush' out of the innerloop (render performance)
SSE -> SSE2 in premake
fix crash in broadphase (when no aabb's exist)
add crude screenshot facility (using F1 key), it can also be used for debugging
start with shadows using shadowmap, not working yet
add experimental 'ignore' body index in raycast, using b3HitInfo.m_m_hitResult2
The Bullet 3.x B3_PROFILE can be customized using b3SetCustomEnterProfileZoneFunc/b3SetCustomLeaveProfileZoneFunc defined in Bullet3Common/b3Logging,
so you can hook Bullet 3.x up to your profiler of choice.
The Demos3/BasicGpuDemo will show the Bullet 3.x timings inside the Bullet 2.x btQuickprof profiler.
implement CPU version of narrowphase convex collision, for comparison/debug purposes
start towards cpu/gpu sync, for adding/removing bodies (work in progress)
y() -> y or getY() or [1]
z() -> z or getZ() or [2]
w() -> w or getW() or [3]
make sphere-convex and sphere-compound collision work (still issues remaining)
added alternative batching kernel (slow)
tweaked controls a bit
added command-line options --selected_demo=<int> and --new_batching
started looking into parallel 3d sap
start adding various scenes to test gpu rigid body pipeline
reserve more memory for shapes (concave triangle mesh can be huge) in GLInstancingRenderer
fix a few crashes when 0 objects
