description         subdivision surface library
long_description    OpenSubdiv is a set of libraries developed by \
                    Pixar Animation Studios that implement \
                    high-performance subdivision surface (subdiv) \
                    evaluation on massively-parallel CPU and GPU \
                    architectures. This code path is optimized for \
                    drawing deforming surfaces with static topology at \
                    interactive framerates.
