OpenGL support should be available on OS X #920

Open darkaegisagain opened 7 years ago

darkaegisagain commented 7 years ago

I was able to build the OpenSubdiv source with OpenGL transform feedback support under OS X, although OS X does not have a complete implementation of OpenGL 4.2 which is required by the current build it has enough features to make this work correctly.

This provides hardware acceleration of OpenGL on OS X and was a simple change in the cmake build system.

You can add me as a contributor and I can make the required changes.

FYI.. I currently work for nVidia and I worked on the OpenGL / OpenCL Framework at Apple for 10 years. Feel free to ask for help, I may know a few things.. 👍

+1 interest in maintaining Mac support

Yes, indeed! The OpenSubdiv XFB implementation should work on Mac, and it does when OpenSubdiv is using GLEW but GLEW should not be required. We'd welcome a PR to fix to the CMake build. Thanks!
