Génération d'atlas de textures de radiosité pour le rendu réaliste en temps réel

Abstract : Radiosity is a method both physically correct and efficient to simulate global illumination. However, huge and complex CAD models are difficult to visualise when simulated by radiosity. In this thesis, we present an approach to optimise visualisation of such illuminated models. It is based on textures atlas that can store illumination in textures which are mapped on models in real time by graphies hardware. Our contributions are : (1) a robust approach to generate atlas and (2) a method to efficiently build those textures from global illumination data, which are both well suited to complex facettized models. The results presented are applied to architectural models and models from design industry. They show that, while this approach is simple to be integrated in an existing rendering software, it allows a real time visualisation of this kind of illuminated models.
