Abstract: In this paper, we use an enhanced surface mass-spring model to simulate virtual dissection by progressive subdivision and re-meshing for cutting and cross-cutting. We introduce novel algorithms to generate interior structures that show the result of cutting generated by the interaction between instrument and model. Our simulator supports two types of cutting: |cut-into|, in which the instrument only penetrates the simulated tissue, and |cut-through| in which the instrument cuts completely through. Haptic force feedback models for interaction between virtual instruments and object are also implemented, which allows the user to feel the contact forces through a haptic device.

Keywords: surface mass-spring modelling; cutting simulation; progressive re-meshing; haptic feedback; virtual dissection; force feedback; virtual instruments; tissue dissection.
