Control on Color Reflection Behavior

Nowadays, most of the computation of a rendering system is done in color space. Thus, the whole process, from acquisition (with a digital camera) and modelisation to display (on CRT/LCD displays) is color-based. Unfortunately, the reflection of a light on a surface is based on an approximation which can reduce the preservation of the color appearance. In this report, we present a new approach for color-based reflection that introduces a low overhead for an easy integration in current rendering systems. This approach allows also an easier control on the reflection behavior. In this report, we present also some possible applications, including global illumination, simple relighting and hardware rendering.
