Abstract

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. 1 Introduction Although simple interactive animation techniques exist and are used in virtual reality systems for instance, they mainly simulate rigid bodies. Using simplified solid mechanics laws, they focus on issues like collision detection and contact modeling, where naive approaches are computationally intensive [Bar96, Fau98]. A smaller amount of effort has been put into deformabl...
