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 31282ab85e don't crash if the maximum number of pairs is exceeded, but report an error using b3Error 2013-06-17 13:23:41 -07:00
erwin coumans 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
 2013-06-14 12:10:16 -07:00
erwincoumans 02a858e7c1 pass in b3Config 2013-06-08 11:32:29 -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
erwin coumans 3f10082aa3 add missing rayCast kernel 2013-06-07 20:47:47 -07:00
Erwin Coumans afecad3ee4 Implemented b3OpenCLUtils::setCachePath 
Also made kernel caching work on Mac OSX (and likely Linux, needs testing before enabling)
 2013-06-07 15:04:46 -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.
