The OpenSubdiv public interface currently requires only C++11 but we
choose this version since C++14 has been the default since GCC 6,
Clang 6, and Visual Studio 2017 (for the most part) and C++14 has been
the default for OpenSubdiv on macOS when support for Metal is enabled.
This setting is guarded so that it can be overridden by the caller when
running CMake.
Fixes#1276
Split the examples/common objects into graphics API dependent object
libraries (following the pattern used for cemmon Ptex dependencies)
so that DX11 and Metal examples are no longer forced to link with GLFW.
Removed the link dependency from libosd to
the Ptex library since Ptex is used only by the
examples. Updated examples/common to separate
the common Ptex sources from the other common
sources so that they are used only by the Ptex
examples.
- updated CMakeLists to account for the moved files
- updated references to argOptions.h in all examples
- added method to ArgOptions to populate vector<ShapeDesc>
- minor changes to ViewerArgUtils to use forward references
These changes update the mtlPtexViewer implementation
to match recent changes to the mtlViewer including:
- improved shader organization
- correct screenspace tessellation
- support for common command line arguments and fit to frame
- 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 mtlPtexViewer to account for recent
API changes to Osd::MTLPatchShaderSource and
also fixed a build error when building with
the use of PtexCache disabled.
