92f2f330df fix OpenCL kernel: NVIDIA crashes in clBuildProgram and AMD reports an error 'irreducable flow detected" ?!? 
ray-convex works on GPU

330bf3ea09 start implementing ray-convex on GPU (work-in-progress) 2013-06-20 11:33:00 -07:00

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.

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.

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

aa1c2db35a Add support for b3Generic6DofConstraint in Bullet, CPU only for now. Also the b3GpuDynamicsWorld supports conversion of this constraint. 
This means, picking works both with and without holding SHIFT (rayTest is only implemented for spheres)

f10eb86f55 enable the GPU ray test in BasicGpuDemo, only for spheres at the moment 2013-06-19 00:12:06 -07:00

481d54967f Fixes in raycast (against sphere), point 2 point constraint 
Picking test works, holding shift in App_BasicGpuDemo_*

9a92eecf10 allow larger amount of rigid bodies, dynamically increase b3Config limits 
avoid crashes in instancing renderer if instance maximum is exceeded.

561a44e5d8 Try to avoid crashes if memory allocations fail 
Deal with cases exceeding allocations of bodies/shapes above the limits set in b3Config
(work-in-progress )

f73d11d896 tweak default values of b3Config.h so some laptop GPUs can run 128k scenes 
return the result of resize
use size_t instead of int for btOpenCLArray
BasicInitialize demo will test how much memory can be allocated, using the btOpenCLArray

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)

afecad3ee4 Implemented b3OpenCLUtils::setCachePath 
Also made kernel caching work on Mac OSX (and likely Linux, needs testing before enabling)

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.
