The focus of the previous chapters has been on the definition of the static representation of objects, mainly for the visualization module of a surgical simulator. However, to model the dynamic biomechanical behavior of soft tissue in a surgical scene, additional components have to be defined. A part of this is the generation of the deformation mesh, which has already been addressed in Section 2.6. In addition to this, appropriate parameters describing the tissue behavior have to be determined. Since the parameter definition depends on the specific deformation model chosen for the simulator, an overview of the common approaches will be provided.
