Pixar has just released a new library into the wild called “OpenSubdiv”, a high-performance subdivision surface library made popular initially with projects like Geri’s Game.
OpenSubdiv is a set of open source libraries that implement high performance subdivision surface (subdiv) evaluation on massively parallel CPU and GPU architectures. This codepath is optimized for drawing deforming subdivs with static topology at interactive framerates. The resulting limit surface matches Pixar’s Renderman to numerical precision.
The full code is available over at Github and released under the Microsoft Public License, making it available for free commercial and non-commercial use.
