Interests	My current research interests are focused on simulating virtual sound fields for interactive applications and computer graphics rendering simulations. I am thus interested in virtual acoustics but also in geometrical techniques used in computer graphics for global illumination problems.
PhD thesis NEW !	You can find here a version of my PhD dissertation: Simulating High Quality Dynamic Virtual Sound Fields For Interactive Graphics Applications. click here for the abstract, citation info, download... click here for the Adobe Acrobat .pdf version (in FRENCH !!!!)
Other interests	I had previously made some research in physically-based animation, implicit surface modeling, surface reconstruction, a 3D lip model for virtual actors and multi-level representations. You can check out my publication list for more detailled information.

NEW !
Using Hierarchical Layered Depth Images for Global Illumination.
I am currently developing a new hierarchical representation for objects in the context of global illumination.
The model allows hierarchical access to the visibility and radiometric information of any number of primitives
represented in a LDI. This representation is used to speed-up ray-intersection tests and also carries
radiometric information in a manner similar to a 'photon map'.

NEW !
Hybrid Beam-Tracing/Monte Carlo Rendering for Acoustics and Computer Graphics.
Click on the pictures for more details on Beam Tracing for Acoustics, Geometrical Theory of Diffraction and Monte-Carlo techniques in the context of interactive acoustics simulations and computer graphics.
I am currently working on a very high quality acoustic simulation code, including fine band geometrical theory of diffraction and early reflections treatment and accurate late reverberation modeling.
I am also working on a hybrid Beam-Tracing/Monte Carlo technique for structured irradiance evaluation.
