Abstract

Lighting computer generated hair is always a challenge. When that hair is 70 feet of long, beautiful, blond locks and belongs to the most famous "long haired" character in Western literature, that challenge becomes daunting. Introduce a stylized art direction that fuses the look of traditionally animated classics like Cinderella and Sleeping Beauty with the tangible realism that marks today's CG animation, and the daunting challenge becomes dubious as well. Mix in a sophisticated, physically based hair shader for good measure and this would describe the rendering process on "Tangled".
