7743f5bce5 Update environment variable to CUDA_PATH (was NVSDKCOMPUTE_ROOT) and fix a few bugs that prevented the NVIDIA OpenCLClothDemo to run properly. 2011-08-17 22:08:10 +00:00
erwin.coumans
e83b5dac75 fixes in the DX11 cloth (for devices with physical wavefronts smaller than 32) 
another fix for out-of-bounds check (there was no assert for this previously)

251bb4e727 remove the 'exit' calls from the OpenCL soft body solver. Use the solver->checkInitialized() method, after solver->optimize() to see if the kernels build OK. 2011-06-30 00:23:42 +00:00

cce582d905 Add support for AMDAPPSDKROOT environment variable 
Initialize vSolveLinksKernel OpenCL cloth kernel (although kernel is unused)

9a9a4394ab fix in btParallelConstraintSolver to support double precision 
fixes in SAT/polyhedral contact clipping, avoid adding GJK contacts (the contact margin causes different contact depths)
add polyhedral convex shape in InternalEdgeDemo as example of the new SAT/polyhedral contact clipping (added reference to Manual/what's new)
avoid glueing objecs with contacts that are positive (no gaps)

b16b61d9d6 disable constraints when they exceed a breaking threshold, control it with new methods in btTypedConstraint: get/setBreakingImpulseThreshold and get/setEnabled 
Disabled constraints are not removed from the world and they use negligible CPU cycles

5b34356c43 Load the ParticlesOCL.cl from memory, using the MSTRINGIFY macro, instead of loading it from disk. 
Small cleanup of cmake build for NVIDIA and AMD OpenCL

For AMD Stream SDK use:
INCLUDE_DIRECTORIES( ${AMD_OPENCL_INCLUDES} )
LINK_LIBRARIES( ${CMAKE_ATISTREAMSDK_LIBPATH}/OpenCL.lib )

For NVIDIA CUDA SDK:
INCLUDE_DIRECTORIES( ${NVIDIA_OPENCL_INCLUDES} )
LINK_LIBRARIES( ${NVIDIA_OPENCL_LIBRARIES})

dd0f022d1d trying to sort out the vectormath include path mess: 
move vectormath to src folder, and add a vmInclude.h that contains the logic in a single location.
If you still need a system-wide vectormath, make sure to define USE_SYSTEM_VECTORMATH (in build system)
