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)

 2013-08-03 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

erwincoumans 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)
 2013-07-15 10:22:40 -07:00

erwin coumans b8d5cecfe3 joint (non-contact constraint) solver iterations is now working on GPU, but overall slower because of data copy. 
Will move joint setup to GPU, and then some benefit should be visible.
Don't use 64 alignment, it causes data structures size mismatch between cpu and gpu

erwin coumans 28f6e0fbd3 towards GPU joint (non-contact) constraint solving. The ConstraintDemo shows that CPU performance is very good, so not much performance win is to be expected. 2013-07-02 21:13:42 -07:00

 2013-06-20 00:29:09 -07:00
erwin coumans a69ba48de4 Move b3Quickprof.* from Bullet 3.x src folder to btgui/Timing 
The Bullet 3.x B3_PROFILE can be customized using b3SetCustomEnterProfileZoneFunc/b3SetCustomLeaveProfileZoneFunc defined in Bullet3Common/b3Logging,
so you can hook Bullet 3.x up to your profiler of choice.
The Demos3/BasicGpuDemo will show the Bullet 3.x timings inside the Bullet 2.x btQuickprof profiler.
 2013-06-19 22:08:03 -07:00
Erwin Coumans 7d79555f50 only disable fastscan in radix sort for __APPLE__, this should improve Linux performance (previously it went through the slower path under Linux) 2013-06-19 23:18:17 -07:00
Erwin Coumans fa4394c378 remove bullet2.patch, the file is not necessary anymore. 
You can use Bullet 3.x standalone, or you can use Bullet3+Bullet2 by checking out the source code of both repositories at the same location,
and then use premake --bullet2gpu gmake (or vs2010, xcode4) to generate the combined project, with App_BasicGpuDemo_* test app.
