In this paper we present a novel data structure combined with geometrically efficient techniques to simulate a "tissue peeling" method for deformable bodies. This is done to preserve the basic shape of a body in conjunction with soft-tissue deformation of multiple deformable bodies in a geometry-based model. We demonstrate our approach through haptic rendering of a virtual anatomical model for a dissection simulator that consists of surface skin along with multiple internal organs. The simulator uses multimodal cues in the form of haptic feedback to provide guidance and performance feedback to the user. The realism of the simulation is enhanced by computation of interaction forces using extrapolation techniques to send these forces back to the user via a haptic device.
