Research

My research areas focus on 3D Computer Graphics, with a special interest in Modeling and Rendering efficiently 3D data, which include:

• shape analysis, from spatial to statistical methods, with application to recognition, interactive modeling and rendering
• geometry capture, processing, editing (see also my older work on interactive shape and appearance editing of large 3D models)
• real-time image and synthesis (see for instance my work on real time tessellation)
• global illumination (see for instance my work on point-based global illumination)
• GPU programming and graphics data structures

For more information, see my publications, my Google Scholar profile and my YouTube channel. See also a recent siminar (in French) I gave at College de France.

Current PhD Students: Adrien Kaiser, Gilles Laurent, Thibault Lescoat, Sylvain Rousseau, Jérémie Schertzer. I also collaborate with Corentin Mercier.
