Takahito Tejima 541aeddd3a Osd API refactor: EvalStencils and EvalPatches ... Add EvalStencils and EvalPatches API for most of CPU and GPU evaluators. with this change, Eval API in the osd layer consists of following parts: - Evaluators (Cpu, Omp, Tbb, Cuda, CL, GLXFB, GLCompute, D3D11Compute) implements EvalStencils and EvalPatches(*). Both supports derivatives (not fully implemented though) - Interop vertex buffer classes (optional, same as before) Note that these classes are not necessary to use Evaluators. All evaluators have EvalStencils/Patches which take device-specific buffer objects. For example, GLXFBEvaluator can take GLuint directly for both stencil tables and input primvars. Although using these interop classes makes it easy to integrate osd into relatively simple applications. - device-dependent StencilTable and PatchTable (optional) These are also optional, but can be used simply a substitute of Far::StencilTable and Far::PatchTable for osd evaluators. - PatchArray, PatchCoord, PatchParam They are tiny structs used for GPU based patch evaluation. (*) TODO and known issues: - CLEvaluator and D3D11Evaluator's EvalPatches() have not been implemented. - GPU Gregory patch evaluation has not been implemented in EvalPatches(). - CudaEvaluator::EvalPatches() is very unstable. - All patch evaluation kernels have not been well optimized. - Currently GLXFB kernel doesn't support derivative evaluation. There's a technical difficulty for the multi-stream output.		2015-05-25 22:43:43 -07:00
