Method RunComputeShader

trinity/Tr2Renderer.cpp:848–882

-------------------------------------------------------------------------------------- Description: Execute compute shaders in all passes of the specified effect. The function will unset bound UAVs after each pass. Arguments: effect - Effect containing compute shaders groupDim# - group grid sizes renderContext - current render context Return Value: true On success false On failure ----------------

//   false On failure
