 2013-08-22 23:15:37 -07:00
Erwin Coumans 74948ede54 fix Linux build 2013-08-22 17:49:59 -07:00
Erwin Coumans d860e7f51a fix Mac OSX build (compound-compound still broken on OSX) 
remove operator= from b3Vector3 to make it POD/Plane Old Data
 2013-08-20 12:45:05 -07:00
erwincoumans 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)
 2013-08-20 03:19:59 -07:00
erwincoumans 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)
 2013-08-08 12:24:09 -07:00
erwincoumans 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
 2013-08-01 21:05:19 -07:00
