Contrôle de l'apparence des matériaux anisotropes

Abstract : In computer graphics, material appearance is a fundamental component of the final image quality. Many models have contributed to improve material appearance. Today, some materials remains hard to represent because of their complexity. Among them, anisotopic materials are especially complex and little studied. In this thesis, we propose a better comprehension of anisotropic materials providing a representation model and an editing tool to control their appearance. Our scratched material model is based on a light transport simulation in the micro-geometry of a scratch, preserves all the details and keeps an interactive rendering time. Our anisotropic reflections edition tool uses BRDF orientation fields to give the user the impression to draw or deform reflections directly on the surface.
