Rivers of Rodents, Lots of Bots, and Cavalcades of Canines: Crowd Simulation at Pixar Animation Studios

p>This talk will start with a general presentation of Pixar Animation Studios and our film making process, followed by discussions of our crowd simulation pipeline and the challenges faced on Ratatouille, WALL-E, and Up.

On Ratatouille, an animation centric crowd pipeline
was born, merging the strengths of our proprietary rigging tools and the commercially available software, Massive. WALL-E demanded fast physics for large crowds, for which the technology "brain Springs" was created. For Up, the focus was flexible navigation and terrain
following for a pack of vicious dogs.

Learn how these crowds came to life and how technological improvements helped bring audiences all those Rats, Robots, and Rottweilers!
