This year I am not presenting anything myself, but a lot of good friends and colleagues will so I will try to attend many tech talks. Do not miss Inigo Quilez's presentation on real time visuals. A lot of that stuff was used, one way or another, on our procedural vegetation and dressing for Brave, it is breathtaking to see a demoscene artist bring this genius into a feature film.
Otherwise, you will find me in the Renderman or Pixar Recruiting booth, or handing out posters and teapots, or in the open standards courses and Birds of a Feather.
I hope to see you there!
