Within the framework of simulators for training of medical procedures, the main issue concerns the interactive simulation of behavior of organs taking into account interaction between them and/or with external surgical tools. The goal of this thesis concerns thus the implementation of a new biomedical model of soft tissues suitable for interactive simulations and allowing simulations of organ movements.
LBMC, LIRIS and Physic laboratory of ENS grouped their skills to create a new physical model based on the topological mass­-spring system (MSS) and mass-tensor model (MT) of LIRIS by integrating the new behavior laws developed by LBMC and Physic laboratory of ENS.
