Abstract

This paper presents a methodology to simulate 3D cuts in deformable objects. It uses an explicit finite element approach to simulate deformations in real-time. We use a non-linear strain tensor formulation (Green tensor) to allow large displacements. Haptics is used to allow touching sensation of the cutting procedure.
