erwincoumans 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
erwincoumans 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
erwincoumans 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
 2013-08-01 21:05:19 -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 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.

erwin coumans 100449d76f faster scene construction when not using instancing (avoid copy individual vertices/shapes to GPU, but do it afterwards in a batch), copy GPU data in 'writeAllBodiesToGpu' method 
add option --no_instanced_collision_shapes, this only applies to the 2 benchmark screnes at the moment
always use the user specified b3Config file, so the settings can be set at runtime, not just at compile time
adjust default constants in b3Config (needs more tweaking, ideally at run-time)
 2013-06-08 11:08:44 -07:00
erwin coumans 3f10082aa3 add missing rayCast kernel 2013-06-07 20:47:47 -07:00
erwincoumans 9fe48d887d b3GpuDynamicsWorld improvements: 
apply forces
copy linear/angular velocity every frame at the CPU side, initial velocity works now
hook up setGravity
Note: the 'stepSimulation' for GPU only simulates a single simulation frame.
