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

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

58eaa609e0 added b3Aabb.h header, can be shared between C++ and OpenCL 2013-08-16 09:13:14 -07:00

b32ae0c75c move some files to shared folders

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)

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)

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

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

7992ff816b use int4 for broadphase pair, it allows to store persistent information in the future 
(contact cache, applied impulse/warm starting info etc)

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

733f9027fb Deterministic simulation for concave and compound collision shapes: added childShapeA/B to b3Contact4 + sort on them

a5d00c8219 add some clFinish for better profile timings 
improved parallel batching, don't try to write for static objects,
this fixed a bug, when the hash of a static object was identical with hash of dynamic objects, causing it to be assigned a bogus 100+i batching number
The parallel batching is still not enabled, because we need to measure the batching size (todo)
