Presentation

Computer graphics are fascinating me, overall real-time images with great visual effects.
I have the chance to work in this field for ten years, now in the ARTIS team in the very pleasant Grenoble town.
My recent works were dedicated to real-time 3D reconstruction and shadows (see Cyber project pages for more info).

Curriculum Vitae

2001-2004: Engineer at INRIA Research Lab

  - working on real-time (soft) shadows
  - developping the CYBER project: your are shot by 4 cameras and then your body is embedded (and can interact) in real-time within a virtual world. It works on an mixed platform and performs at 30Hz video capture, background subtraction, network transmission, reconstruction, interaction and rendering.

1994-1999: Engineer at EDF Research Departement
