This paper presents an approach to animate elastic deformable materials at interactive rates using space-time adaptive resolution. We propose a new computational model, based on the conventional Hooke's law, that uses a discrete approximation of derivative operators on irregular sample points. It allows local refinement or simplification of the computational model based on local error measurement. We in effect minimize calculations while ensuring a realistic and scale-independent behavior within a given accuracy threshold. We demonstrate this technique on a real-time virtual liver surgery application.
