In this episode, Pixar Simulation Supervisor Claudia Chung takes us behind the scenes of hair and cloth simulation for Brave.

Pixar Simulation Supervisor Claudia Chung demonstrates one the ways digital filmmakers at Pixar ensure accurate movement of digital objects: they create the objects first in real life. Pixar computer artists used real wigs and costumes as reference for developing algorithms that mimic hair and cloth within a computer. Photo by Deborah Coleman / Pixar. All rights reserved.
