Abstract:
Haptic simulation of virtual tissue cutting is computationally intensive. The challenge is to simulate virtual cutting without simplifying assumptions. Unlike earlier works we achieve realism and real time performance by decoupling graphics and haptics. We propose a hybrid model of fuzzy and Kelvin model to achieve our goals. While the Kelvin model computes the collision response using position, time, and velocity representing transient effects, the Fuzzy model computes the force using depth and velocity, thereby including both transient and static properties of cutting in our simulation. Compared with conventional physical based modeling, the computation of force is independent of the geometry model of the cutting surface
