Overview


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 code embodies decades of research and experience by Pixar, and a more recent and still active collaboration on fast GPU drawing between Microsoft Research and Pixar.

OpenSubdiv is covered by an opensource license and is free to use for commercial or non-commercial use. ¬†This is the same code that Pixar uses internally for animated film production. Our intent is to encourage high-performance, accurate subdiv drawing by giving away the “good stuff.”

The source code for OpenSubdiv is located on github.  Feel free to use it and let us know what you think:

OpenSubdiv supports a wide variety of software APIs on Linux, Windows, OSX, and Android.
