I work on Rumba, a 3D animation software- developped multithreaded synchronous evaluation engine, task graph is optimized and reused for real-time scene update during interaction, added different levels of caching, fast invalidation and constant/varying analyses, multi-frame editing- developped multithreaded background evaluation engine, with efficient and parallel task graph construction, quickly stopped on invalidation, relaunched when interaction is over, progressive caching- improved and extended rendering engine, with parallel render graph construction and evaluation, multi-frame rendering such as motion trails and onion skins, automatic redraw on render graph invalidation- profiled and optimized interaction, rendering, evaluation, caching, playback, playblast, export and deserialization processes; optimized memory usage- designed portable and multi-platform building and testing processes; created Windows and Linux packaging process- added reflexion, serialization/deserialization, and python bindings by specifying metadata once- added audio engine module, rig compilation and protection

Apart from my researches on intuitive and direct interactions with 3D shapes, I had both administrative and teaching responsibilities. Indeed, I was in charge of the valorization and referencing of scientific publications, as well as helping to write report for a project funded by the European Union. Among my teaching activities, I created a set of practical lessons in 3D Computer Graphics, supervised a final year project in Computer Graphics as well as many specialty projects in the same field.

Mes recherches sont sur l'application des squelettes pour permettre de modéliser et d'interagir de façon naturelle avec des formes en trois dimensions. En particulier, je propose des solutions pour habiller un squelette (construire un maillage capturant l'apparence d'une forme décrite par le squelette), pour le nettoyer de son bruit, et pour construire une organisation utile de ses éléments. Cette organisation du squelette le rend apte à être utilisé pour la segmentation, l'animation, la déformation, la simplification et la création intuitive de formes 3D.Cours magistraux, travaux dirigés et travaux pratiques à monter et animer au sein de deux formations :- licence professionnelle Gestion de Système Informatique en Entreprise- ingénieur en génie industriel en partenariat avec l'ITII Bourgogne.

During my PhD, I decided to work on intuitive shape interaction with 3D shapes. In particular, I focused on shape visualization, creation, segmentation, animation, deformation and animation. I proposed to use the median surface as a basis to build a shape representation and shape interaction structure for the general public. The key idea was to take advantage of the intuitive potential of skeletal representations.The main difficulty was to perform required operations, like visualization, denoising and hierarchization, using the median surface only while all existing solutions need to know both the median surface and the another shape descriptor. I solved this issue using computational geometry to build a set of tools to process, analyze and enhance an input median surface in order to build the meso-skeleton, a hierarchical structure that describes the shape and can control all its characteristic parts.
