Simulating and Rendering of Degraded Fabric Colors

Abstract

Surface appearance is very important for creating realistic materials in computer graphics. In nature, the surface color of fabric objects changes as it interacts with the environment over time. Traditional material models in computer graphics are inadequate for modeling color changes of fabrics. In this paper we describe the acquisition and modeling of degraded fabric colors. We use photo-degradation to simulate the environmental interactions that create the color changes of fabrics and introduce a new aging model to predict degraded fabric colors. These simulations will be extended to model a physically motivated material model for fabrics in rendered scenes.
