Transferring a labeled rig to animate face models

Abstract

We present a facial deformation system that adapts a generic fa- cial rig into di®erent face models. The deformation is based on labels and allows transferring speci¯c facial features between the generic rig and face models. High quality physics-based animation is achieved by combining di®erent deformation methods with our labeling system, which adapts muscles and skeletons from a generic rig to individual face models. We describe how to ¯nd the correspondence of the main attributes of the generic rig, transfer them to di®erent 3D face models and generate a sophisticated facial rig based on human anatomy. We show how to apply the same deformation parameters to di®erent face models and obtain unique expressions. Our goal is to ease the char- acter setup process and provide digital artists with a tool that allows manipulating models as if they were using a puppet. We end with di®erent examples that show the strength of our proposal.
