David G Yu	838fce27ab	Exposed control for Gregory derivative weight eval ... The symbol OPENSUBDIV_GREGORY_EVAL_TRUE_DERIVATIVES determines the method used to compute derivative weights for Gregory basis patches. Setting this symbol during CMake configuration (and hence during C++ and shader compilation) will enable the use of true derivative weights. The default behavior is to use a simpler approximation for consistency with earlier releases.	2016-10-11 18:50:25 -07:00
David G Yu	710da328f9	Fixed Osd::CudaEvaluator ... - Fixed the size of a cudaMemcpy - Fixed the use of local "static" storage	2016-09-29 20:27:43 -07:00
David G. Yu	552331f6d9	Added a common patchBasis implementation for Osd ... This is used to compute patch basis weights for the Osd::*Evaluator classes that are unable to use the C++ implementation from far/patchBasis.h, e.g. the GLSL, HLSL, OpenCL, and CUDA kernels. Instead of duplicating this code for each different kernel language, we share a single implementation which is minimally adapted to accommodate specific language restrictions and syntax. This implementation can also be used by client shader code executed while drawing, e.g. to compute patch basis weights for evaluating varying and face-varying patches.	2016-09-29 09:53:40 -07:00
