title: Fast finite elements for surgery simulation.
abstract: This paper discusses volumetric deformable models for modeling human body parts and organs in surgery simulation systems. These models are built using finite element models of linear elastic materials. To achieve real-time response condensation has been applied to the system stiffness matrix, and selective matrix vector multiplication has been used to minimize the computational cost.
