|I am a Professor of Computer Science at University Joseph Fourier, Grenoble, doing research at INRIA,LJK-CNRS. My research work addresses Physical Simulation for Computer Graphics, both from a modelling and a computational perspective. My recent work includes new deformation models for continuous media mechanics, GPU accelerated collision detection and response, software architecture for heterogeneous simulation, and parallelization on hybrid hardware architectures. I am one of the lead architects of the SOFA simulation library.

- My current interests include, but are not limited to: deformable models, contact detection and modeling, simulation software architecture, in collaboration with numerous co-authors. The following is a selection of my recent work. See also my complete publication list.
Physically accurate deformable models are usually designed using Finite Elements (with meshes) or Particle Systems (without meshes). To alleviate the well-known meshing and discretization issues, we have developed frame-based meshless models. They combine the physical soundness of continuous media mechanics used in physics with the ease of skeleton-based deformations used in traditional computer animation. Recently, we have been using these methods to morph anatomical models. Click on the following images to access the associated pdf, images and videos.

Contact Detection and Modeling
Traditional distance-based collision detection and response is hard because the detection inherently has a quadratic complexity, and penetration depth is a complex, ill-posed problem. We tackle these challenges using a discrete depth-based intersection detection and the minimization of the intersection volume. This allows very efficient implementations on the GPU which return not only a list of contacts, but also repulsion directions.

Programming mechanical simulations for computer graphics requires skills in various domains such as mechanics, numerics, geometry, graphics, etc. We have proposed a modular software architecture inspired from graphical scene graphs, which allows programmers to focus on their own domain of competence while easily combining and re-using modules created by others. This is available in the open-source SOFA simulation library, increasingly popular in the Computer Graphics and Medical Simulation domains.
