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)

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)
 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

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)

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

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 
Use tetrahedra instead of barrel for convex demo (until performance for edge-edge is improved)

ab125fbb6d implement GPU breakable constraints 
add GPU fixed constraint
fix performance issue with concave meshes (didn't clear the number of concave-convex pairs, so it increased every frame)

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)
