Since September 2006 I joined the REVES team at INRIA Sophia-Antipolis (France) as a permanent researcher.

Some more information about my work is also available on sylefeb.aracknea-core.net.

Short bio

I did my PhD at INRIA Rhones-Alpes (Grenoble) in iMAGIS/EVASION team, under the supervision of Fabrice Neyret. My PhD work was about advanced texturing methods using GPUs (see also my thesis webpage). After graduating I joined Microsoft Research, Seattle, as a postodctoral researcher during the year 2005. I worked with Hugues Hoppe on real-time texture synthesis and texturing. I became an INRIA researcher in September 2006.

In my rapidely shrinking spare time I enjoy both playing and developing games (check out my game projects Etees, Jalweg, and Ragdoll smasher).

Video overview

Here is a small video overview of what I did these past years (from 1999 to 2005), including research but also other (less-serious :-) projects.

We just finished the final version of our I3D 2007 paper: TileTrees. The paper is available here.

These days I have been implementing a sky model for a project on natural phenomenons. Nothing new, just cool images :-)
The model is based on the work of Naty Hoffman and Arcot J. Preetham Rendering Outdoor Light Scattering in Real Time. A more recent version of their work is also available in the book Graphics Programming Methods by Charles River Media.
For those interested, here is the shader.
