Hair Emoting with Style Guides in Turning Red

For Pixar’s feature film Turning Red, the grooming and simulation teams faced the challenge of handling characters with millions of fur and hair curves, which often needed to behave differently in each shot reflecting the characters’ emotional states. This work describes new tools developed to assist artists in managing and sculpting these large amounts of fur and hair. In particular, we present a novel surface-aware technique for curve deformation that interpolates hair sculpts at varying levels of detail, accompanied by a customized user interface for interactively browsing hair layers.
