Volumetric Deformable Models for Simulation of Laparoscopic Surgery

In this paper we present a method for solving both problems of force feedback and real time deformations of virtual organs, especially needed for surgical simulators. Our method is based on the linear elasticity theory with a preprocessing algorithm which entails real time performances. We have applied this technique to a liver model derived from a complete anatomical representation.
