Welcome to Sylvain Vignaud's web page

My name is Sylvain Vignaud and I'm a programmer working on real time 3D application such as video games and simulators.

I worked on several games from the Star Wars, Prince of Persia, Your Shape Fitness Evolved licenses; and from now on the next BioWare games. Here's the list of video games I worked on, ranging from strategy to management and platform/action, running on handheld, salon consoles and PC.

I now work at Google

My resume.

I've taught myself to program on Apple ][ and on PC since the 80ies, and I started programming 2D graphics in assembly since 1993, 3d software renderers in 1997 and GPU accelerated software in 2001.
I love pushing the limits of what's possible, optimizing as much as possible and doing effects no one has done before. Some example of such achievements are:

Conformal Foveated Rendering: a foveation method assigning pixels to the final image with a variable density (more in the acute area).
Standard foveated rendering on the left, C-FR on the right:
Temporal Anti-Aliasing
Fast 3D Metaballs on GPU.
My implementation of Crytek's Massive Lighting.
Per vertex pseudo global illumination in real time on CPU.
Complex and animated realtime shadows on Nintendo DS.
Soft shadows on TNT/TNT2/Geforce2's fixed pipeline.

Here are some thoughts about:

Optimizations.
3D face reconstruction of human face which I worked on in school.
Technical and programming links.
