“Modeling interaction with deformable objects in real-time”

Most surgical simulations require modeling of deformable objects. Given an appropriate elastic model we may either solve for an static equilibrium or analyze the evolution of the system with respect to time. We present both non-linear
static solutions and various time integration methods (notably explicit and implicit) and discuss their relative merits in the context of surgery simulation. Models of the human liver and thigh are used to exemplify the process.
