!! Looking for a job !! I'm looking for a new position as a graphics engineer, in Canada ! Ideally in Montréal, in a video game studio, animation, special effects, or research lab. Feel free to contact me if you're interested in my skills !

I am a computer graphics engineer working in ARTIS since January 2008. I worked for almost 2 years on GENAC project (Automated Content GENeration) with Cyril Soler and Eden Game studio (Lyon,France, has recently shipped Test Drive Unlimited 2 and Alone In The Dark - Near Death Investigation), on global illumniation for video games.
Currently I work on GARDEN project (next-gen video game engine, still collaborating with Eden Game), on realistic real-time rendering for video games.

Research themes

GENAC project:
My research works are about real time global illumination for video games, more specifically about ambient occlusion and indirect lighting computation in screen space, using deffered rendering engine.
About SSAO: our method aims at computing visible horizon in every direction, around each point (similar to HBAO method from nVidia). Some videos after integration in Alone In The Dark game engine.

• First results using high quality parameters
• Another video showing quality benefits from temporal coherence, using low quality parameters (quarter resolution, 16 samples/pixel).
• (All videos were shot in real time, at a resolution of 720p)

About SSIL: our method compute indirect lighting in a hierarchical way, using low resolution version of G-Buffer. We also adapt Monte-Carlo integration formula to fit screen space computation.

• All details are in technical report as well as in my Siggraph'10 talk slides(.pptx / .ppt / .pdf)
• Our results within Alone In The Dark game engine (real time, 720p)

GARDEN project:

• Realistic foliage rendering: our method use tile rendering with high-end hardware features
• Terrain generation: procedural terrain generation from example, with respect to user-defined constraints. First promising result: we synthesize terrain from a heightmap example (procedurally generated or manually drawn by an artist), respecting user-defined track.
