Creating Animatable Non-Conforming Hexahedral Finite Element Facial Soft-Tissue Models for GPU Simulation

Physically-based animation techniques enable more realistic and accurate animation to be created. Such approaches require the creation of a complex volumetric model that can be realistically and efficiently simulated, particularly for interactive computer graphics applications. We present an approach to automatically construct animatable non-conforming hexahedral finite element (FE) facial soft-tissue simulation models, including automatic determination of element material types, boundary conditions and muscle properties, making them immediately ready for simulation.
