Interactive Multiresolution Animation of Deformable Models

By Gilles Debunne, Mathieu Desbrun, Alan Barr and Marie-Paule Cani


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 differential operators on irregular grid. 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 scaleindependent behavior within a given accuracy threshold. We demonstrate this technique on a real-time virtual liver surgery application
