  • 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) erwincoumans 2013-08-20 03:19:59 -07:00

  • 3bf003ace1 change lcpp Lua preprocessor, to keep #defines and comments, remove empty lines 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) erwincoumans 2013-08-08 12:24:09 -07:00

  • 906415429c added (and stripped) a simple C/C++ preprocessor (written in Lua), so the stringifier can handle the #include directive, 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 erwincoumans 2013-08-01 21:05:19 -07:00
