erwin coumans e85bae5fe3 share more data structures and code between OpenCL kernels and C/C++ code on CPU (non-OpenCL) 
integrateSingleTransform
fix bug in registerRigidBody (could lead to random crashes, especially when performing picking/adding rigid bodies afterwards)
 2013-11-07 15:49:57 -08:00
erwincoumans 181a323631 move b3RaycastInfo.h so it can be used without OpenCL dependency

 2013-08-20 12:45:05 -07:00
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.

 2013-07-17 16:11:54 -07:00
erwin coumans 1e31073f4b made the simulation deterministic 
disable 'simdwidth' optimization for determinism (need to double-check)

erwincoumans d935eb2520 fixes in ray-convex for GPU 2013-06-20 16:27:36 -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 161c48d331 work-in-progress Bullet 3.x GPU raytest 
work-in-progress P2P constraint for b3GpuDynamicsWorld
 2013-06-17 13:47:35 -07:00
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
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.
