ad8d0e32f4 expose 2 new command-line options [--disable_cached_cl_kernels] [--load_cl_kernels_from_disk] 
on Windows (_WIN32) debug output goes to BOTH console and Visual Studio output log window.

d32629dbe2 add the option to load a set of AABB's from a file, see PairBench 
You can use the following command-line arguments:
App_Bullet*.exe --selected_demo=10 --cl_platform=1 --pair_benchmark_file=64006GPUAABBs.txt --benchmark

2c019d579f reduce memory allocation, lack of GPU memory totally destroys performance on my GTX 650M on the Macbook retina 
add some keys to toggle gui drawing and shadows

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)

41ba48b10d fix compound-compound tree/tree collision on the host side (still need to implement it for all cases, and on GPU/OpenCL) 2013-08-16 10:33:38 -07:00
erwin coumans
58eaa609e0 added b3Aabb.h header, can be shared between C++ and OpenCL 2013-08-16 09:13:14 -07:00

ef224370ab implement compound versus compound BVH acceleration (quantized tree-versus-tree, using subtrees and quantization) on host 2013-08-16 08:58:52 -07:00
erwin coumans
b32ae0c75c move some files to shared folders 
use b3Aabb for compound vs compound on host (for testing, towards BVH)

678f634699 fix compound collision (host side) 2013-08-11 20:02:07 -07:00

ac23dbc4be contact normal should point from B to A (to be consistent with Bullet 2.x) 
stringify: pre-allocate bigger buffer (10MB, workaround)

d158507c03 remove m_localPosA for now (it breaks NVIDIA OpenCL, copy of structs > 128 bytes) 2013-08-08 13:28:23 -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

46a08e3282 add missing header file, test case for sharing code between C++ / OpenCL 
The headers are recursively embedded, only the necessary parts (skipping parts behind undeclared ifdefs)
 2013-08-03 11:12:51 -07:00

18eed5b067 further work towards sharing structures/code between C++ and OpenCL 
(could break the build in C++/OpenCL)
 2013-08-03 10:13:13 -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

34de49d8a4 add gjk/epa (host only), possibly improve convex-convex with many edge-edge tests 
more preparation towards persistent/incremental contact cache
 2013-07-31 23:22:43 -07:00

7992ff816b use int4 for broadphase pair, it allows to store persistent information in the future 
(contact cache, applied impulse/warm starting info etc)
 2013-07-31 09:58:15 -07:00

338118b3c6 expose the number of frame that the benchmark mode runs as commandline parameter: 
for example --max_framecount=1000

1c0fc6bc2d report when compound pair capacity is exceeded (and avoid crash) 
add tetrahedron, reorganized demos
 2013-07-30 17:00:50 -07:00

2793a174c6 added fracture scene .bullet file (doesn't work well yet) 
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)
