We present a novel approach to building realistic 3D facial appearance models. We seek to efficiently model a single human face by encoding raw 3D geometrical data and texture from scanners in a model suitable for statistical treatment. Preparation of our models requires minimal human interaction and, once built, our models can be used for real-time facial animation intuitively controlled by a small number of parameters, ready for rendering on consumer-class graphics hardware. Our method robustly handles poor-quality or deficient sample meshes and allows for processing of shape data in 2D mode using established image processing algorithms. Additionally, we discuss applications of our model to mechanical modelling and simulation of cephalofacial dynamics. We present a computationally efficient approach to statistically constrained unconditionally stable mechanical simulation with explicit integration scheme.
