PhD Proposal

My PhD proposal (in French) is available here . The proposal has been (successfully ^_^ ) defended at the Université de Montréal during summer 2007.

2005

Master Thesis

My master thesis (in french) is available here and its associated webpage with more results is there. This thesis was written under the supervision of Xavier Granier. It proposes a new structure, an octree, to reconstruct the indirect irradiance. Each voxel face stores six irradiance vectors (as propose by [Arvo94]) computed using particle tracing and density estimation techniques. We also propose a compression scheme for irradiance vectors to minimize the memory footprint of our structure.

"Efficient Approximations for Global Illumination " (Research Summary)

Abstract : ''An Approximate Global Illumination System for Computer Generated Films'' presents for the first time a complete rendering framework with Global Illumination capabilities used to produce Shrek 2. Although this article does not introduce significant innovations for the research area, the introduced framework allows artists to easily incorporate Global Illumination effects and quickly gives them visual feedback. To achieve this amazing feat, Dreamworks and PDI have modified existing acceleration techniques and made geometrical and physical simplifications. This document reviews them and presents alternative or complementary published techniques that may also be used as efficient simplifications.

This work was done for the "Initiation �la Recherche" course during the first term of my Master in Bordeaux.

Internship Report

This report was done during a summer internship in Montreal with Pierre Poulin. It investigates the possibility to use ray differentials in lighting context. It also discuss some issues when implementing ray differentials to filter textures.

The report is available here (in french).
