Modélisation et rendu d'images réalistes de paysages naturels. (Modeling and Rendering of natural landscapes realistic images)

Représentations d'arbres réalistes et efficaces pour la synthèse d'images de paysages. (Efficient Rendering of Realistic Trees Representations for Computer Graphics)

This PhD thesis is dedicated to the representation of trees for high quality or real timelandscapes rendering. Techniques of tree modeling give good results in terms of diversity of species andshapes. However, the multitude of polygons of their geometrical representations generates a high computingcost and important problems of aliasing at rendering. Mesh simplification in order to ...

Jerry Tessendorf Principal Graphics Scientist Rhythm & Hues Rapporteur

Video games and visual effects are always in the need for more realistic images of natural scenes, including clouds. Traditional computer graphics methods involve high amounts of memory and computing resources which currently limits their realism and speed. In this thesis we propose new approaches for the realistic rendering of clouds in realtime. These goals are achieved using a methodology re...

Modeling Glioma Growth and Personalizing Growth Models in Medical Images. (Modélisation de la croissance des gliomes et personnalisation des modéles de croissance à l'aide d'images médicales)

Image-Based Rendering from a Single Image

In this report, we present a new method to recover an approximation of the bidirectional re ectance distribution function (BRDF) of the surfaces present in a real scene. This is done from a single photograph and a 3D geometric model of the scene. The result is a full model of the re ectance properties of all surfaces, which can be rendered under novel illumination conditions, with, for example,...

A Procedural Approach to Style for NPR Line Drawing from 3D models

This paper introduces a procedural approach to non-photorealistic line drawing from 3D models. The approach is inspired both by procedural shaders in classical rendering and by the power of procedural modeling. We propose a new image creation model where all operations are controlled procedurally. A view map describing all relevant support lines in the drawing is first created from the 3d model...
