Physically-based forehead animation including wrinkles

Physically-based animation techniques enable more realistic and accurate animation to be created. We present a fully physically-based approach for efficiently producing realisticlooking, natural animations of facial movement, including animation of expressive wrinkles. This involves simulation of detailed models using a GPU-based total Lagrangian explicit dynamic finite element (TLED FE) system. The flexibility of our approach enables detailed animations of gross and fine-scale soft-tissue movement to be easily produced with different muscle structures and material parameters, for example, to animate different aged skin. While we focus on the forehead, our approach can be used to animate any multi-layered soft body.
