An Art-directed Workflow for Transferring Facial Action Coding Between Models With Different Mesh Topologies

摘要

In this paper, we present a simple and intuitive approach to transfer existing FACS (Facial Action Coding System) based facial rig and its data set on to a different facial model that has a different mesh topology to support rigging and animation pipeline for visual effects films, 3D animations, and video games. Facial rigs are custom built for each character and are time consuming and complex to create, and even minor tweaks on the model typology may cause the rigging process to start from scratch. In order to maximize the data reuse, this system can apply one set of data onto a variety of human or creature facial rigs.
