Simulating Rapunzel's hair in Disney's Tangled

ABSTRACT

Hair simulation is known to be a complex problem in animation. In Tangled we have the extreme task of simulating 70 feet of hair for the film's main character, Rapunzel. The excessive hair length in addition to the loose style and intricate structure of the hair present many unique challenges in simulation. Moreover, the specific art direction of the film adds to the complexity of the simulation.
