- updated PrimvarRefiner to make use of now-local Mask class
- renamed vtr/maskInterfaces.h to vtr/componentInterfaces.h
- updated usage of renamed header file and CMakeLists.txt
It looks like there's a compiler bug in some earlier nvidia driver 340/346 releases.
It has been fixed in 348.07 (win) as far as I can tell.
Following code behaves incorrectly.
void f(int a) {
for (int i=0; i<3; ++i) doSomething(a, i);
}
void g() {
for (int i=0; i<100; ++i) f(i);
}
The workaround is to use different identifiers for each function.
- removed TopologyRefiner options to propagate base face in Refinememt
- removed all Vtr storage and management of base face
- added PrimvarRefiner methods to "interpolate" per-face primvar data
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.
* Added stencilTable.cpp
* Fixed the "off" variable shadow warning
* Moved constructors to cpp file
* Made LimitStencilTable constructor private
* other minor clean up.
- created new class Far::PrimvarRefiner with interpolation methods
- removed interpolation and limit methods from Far::TopologyRefiner
- replaced internal usage in Far::StencilTableFactory
- replaced usage in regressions, tutorials and examples
