Software
I develop a few Open-Source libraries and scripting tools related to Computer Graphics, Research and Teaching
Programming library
[CGP] Computer Graphics Programming library.
A C++ library for simple 3D programming with a dedicated focuss on teaching purpose (simplicity, debuging).
Open-Source Research Protoype
[Velocity Skinning]
Several Implementations (C++, GPU, JavaScript) of the Velocity Skinning for Real-Time Cartoon Deformer on Skinned Characters.
Scripting tools
[Static Website]
A static website generator in Python using jinja2 (and LHTML) with pre-made templates compatible to generate HTML Slides and Tutorial webpages.
[LHTML] Lightweight HTML parser
A lightweight parser converting a few keyword for quick HTML with embedded CSS webpage writing. Inspired from markdown, but defined to only add keyword on top of HTML code.
[Hal Publication]
A JavaScript and template to query and display HAL publication listing. Allows to add local additional information such as Conference+Journal, Code, Project page, etc.
[AFIG Listing]
A few scripts for collaborative listing of CG companies, online courses, research teams.
Short Presentation & Bio
I am a Professor of Computer Science at Ecole polytechnique, part of Institut Polytechnique de Paris. My research focuses on Computer Graphics, specifically in 3D modeling, Deformation, and Animation of virtual content, with an emphasis on Real-Time Efficiency, Interactivity, and User Control. I have contributed to to the Modeling and Animation of Virtual Character, Developable Surface, 3D Garment models, and to the Simulation of Natural Phenomena. I try to couple procedural approaches and lightweight physics, with the use of appropriate geometrical representation featuring for instance hierarchical level of details and field based representations. The typical application of my research are for entertainment production recquiring efficiency and interactivity such as Animation Cinema, VFX, and Games, with publications in Graphics journals and venues including SIGGRAPH, Eurographics, SCA and MIG. I additionally enjoy collaboration with other disciplines such as Medical Sciences, Math, or Design.
I obtained my PhD in 2011 from Grenoble University. I also hold an Engineering Degree from CPE Lyon in Computer Science and Electrical Engineering (2007), a Master in Optics, Image and Vision from Université Jean Monnet at Saint-Etienne (2007), and a Habilitation (HDR) from Grenoble University (2017).
I am currently serving as Vice-Director of LIX, and leading the VISTA research team.
I was conference chair of SCA2017, program chair of MIG2021 and IMET2023, and I am regularily part of multiple IPC such as Eurographics, Pacific Graphics, SCA, MIG, Siggraph and Siggraph Asia Posters, Shorts and courses. At the national level, I was part of the sterring commity of AFIG - French Association in CG between 2015 to 2024.
I am widely involved into education, encompassing teaching at various level, including master and bachelor programs in CG, 3D animation, as well as Web Programming, and engage in tutoring numerous student projects. I am also coordinating the Image, Vision and Learning specialization at Ecole polytechnique, and actively contribute to the organization of the Interaction, Graphics & Design Master program at IP Paris. I further enjoy proposing and developing open-source content and softwares in order to facilitate accessibility and re-usability to students and the scientific community. These include a set of open-source online course slides and practical exercises in CG and Animation, and an entire programming library framework (CGP). I am also the main developer of open community-driven listings for existing Graphics companies, available positions, french research teams, and educational content.
