I have replaced my old Gregory patch pipline with Pixar's OpenSubDiv library.
I presented at Pixar on 12/16/2013.

This was an incredible experience. Thank you to everyone involved for having me over!
OSD has been painless to integrate, stable and performs well:

I have also spent a large amount of time implementing a realtime probe sampling variant of physically based shading using importance sampling inspired by the Unreal presentation at Siggraph this year.
