The Siames team works on the simulation of complex dynamic systems and the need of 3D visual restitution of the results. These results could be producted in real time or in batch, depending on the nature of the simulated phenomena. Our scientific activity concerns the following points:
motion of dynamic models for animation and simulation: in this field, our work deals with the modeling of physical systems, the control of these systems and all kind of interaction that could occur during the simulation. Special attention is given to contact and collision algorithms.
behavioral simulation of autonomous entities: this topic concerns both the interaction between entities and the perception, by the entity, of the surrounding environment. The geometrical information is too poor to take into account the potential relationships between a behavioral entity and its static and dynamic environment. In order to provide high level interaction, topological information on space organization and on the objects of the environment is added to data structures.
lighting simulation: in complex architectural environments, light propagation and interaction with object material generate a big amount of computation using a lot of memory. Our work on this subject concerns the use of a standard workstation or a network of workstations in order to provide the simulation results. This simulation also has to provide tools for the visual characterization of the quality of the results from the human perception point of view.
