Fixed smooth face-varying interpolation for the Metal viewer
when using screen-space tessellation. The location to evaluate
the face-varying value needs to match the computed tess location
instead of the intrinsic position_in_patch.
- added definition to regression/common/shape_utils.h
- removed examples/common/shapeDesc.h and all references to it
- removed local definitions of ShapeDesc from examples, regressions, etc.
- overloaded Shape::parseObj() with ShapeDesc
- updated examples to use Shape::parseObj(ShapeDesc const&);
- removed axis argument to Shape::ParseObj() and ObjAnim::Create()
This fixes the build when trying to build both the Metal examples
and the GL examples in the same build. The change is an unfortunate
consequence of how dependencies are bundled together in
examples/common and a future task is needed to split up these
dependencies. The same workaround exists in the DirectX examples as
well and would also benefit from splitting up the dependencies.
- changed the main OPENSUBDIV_INCLUDE_DIR to exclude ./opensubdiv
- updated CMakeLists.txt files in non-examples to use only this path
- updated CMakeLists.txt files in examples to append ./opensubdiv to path
- updated source in regression/common to use #include <opensubdiv/...>
- updated source in examples/common to use #include <opensubdiv/...>
- deferred source in examples to be updated on a case-by-case basis
Updated Metal patch shaders to resolve degenerate normals.
This fix was ported from the GLSL patch shader source.
Also, added missing inf sharp test cases to mtlViewer.
