erwincoumans 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)
 2013-07-17 16:11:54 -07:00
erwincoumans 6d7d2531b5 Merge branch 'master' of https://github.com/erwincoumans/bullet3 2013-07-16 19:05:34 -07:00

erwincoumans b448e56a51 add basic CPU multi threading files from Bullet 2.x (still need to make it work) 2013-07-16 18:16:54 -07:00
erwincoumans 20f9e41ff0 remove some debug printf's from kernel (stringify doesn't handle it properly) 2013-07-15 10:36:02 -07:00
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
erwincoumans 05ed1fdbcf revert to useNewBatchingKernel, the other one is broken (need to figure out why) 2013-07-15 01:06:04 -07:00

erwin coumans c4375a09e4 added GPU joint solver for non-contact constraints. Only point 2 point version for now, will add some other constraints soon (changes are very local) 2013-07-09 10:46:47 -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
 2013-07-06 14:11:32 -07:00

erwin coumans 956c3fc267 Merge branch 'master' of https://github.com/erwincoumans/bullet3 2013-07-02 21:13:54 -07:00
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

erwin coumans 92f2f330df fix OpenCL kernel: NVIDIA crashes in clBuildProgram and AMD reports an error 'irreducable flow detected" ?!? 
ray-convex works on GPU
 2013-06-20 11:50:19 -07:00
erwin coumans 330bf3ea09 start implementing ray-convex on GPU (work-in-progress) 2013-06-20 11:33:00 -07:00
erwin coumans c959f32d7e added b3Clock/b3Quickprof files 2013-06-20 10:14:21 -07:00
erwin coumans 531af1b394 add ray-convex CPU implementation, make CPU raytest default for now 
tweak/increase the b3Config values again, so it works better on the Macbook Retina GPU.
 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
erwincoumans 6acf4d03a7 add Raycast kernel to stringify_linux.sh 2013-06-19 17:29:31 -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.
