Simulation of surgery and medical procedures requires developing models of human organs and tissues, medical devices, and interactions among them. Geometric and physical characteristics of real objects are built into virtual models which form foundation of accurate and fast computation of real-time and interactive simulations. We have been developing methods and techniques for modeling various medical simulations.
