Overall Objectives

The main context of our research activities concerns the simulation of complex systems. Indeed, our research topics deal with lighting simulation, mechanical simulation, control of dynamic systems, behavioral simulation, real time simulation and modeling of virtual environments.

Our studies are focusing on the following topics:

Computer Graphics: our main works concern the design and integration of models, the design of new algorithmsand of the complexityof the proposed solutions.

Simulation: our main goal is to be able to compare the results produced by our simulation algorithms with real data in order to experimentally validateour approaches.

Systemic approach: in order to validate the two previous points, we have to be able to treat real industrial test casesthrough the use of realistic implementation of our solutions.

More precisely, our studies deal with three complementary research themes:

lighting simulation: realistic image synthesis algorithms give high quality results by the use of physical based illumination models in order to evaluate the light / material complex interactions.

physical system simulation: first, our approach concerns the computation schemes needed to produce the state equations of the system (symbolic and/or numeric computation). Second, we are concerned by the control of these physical systems (virtual characters,...). In this field, we focus our attention on computer animation and simulation.

behavioral modeling and simulation: in order to simulate the behavior of living beings in specific tasks, we design tools dedicated to the specification and simulation of dynamics entities (autonomous or semi-autonomous). Our behavioral models integrate continuous and discrete aspects, in one hand to be able to control motor capabilities of the entity and, in other hand, to take into account cognitive capabilities. We also focus our research activity on the virtual environment modeling process. In this field, we integrate, in the modeling process, geometrical information as well as topological and semantic information.

Two transverse topics are also very active:

Virtual Reality: this field deals with some of our research topics such as lighting simulation, animation or simulation. Our approach adresses real industrial problems and proposes new solutions using our research results. The objective is to adapt the simulation of complex systems to the haptic constraints induced by the interaction by human beings.

OpenMASK software simulation platform: the need of integration of our different research activities has produced a real time and distributed Virtual Reality and Simulation environment. This software is distributed according to an Open Source model (see
