Abstract

Interactive rendering is usually made with very simple illumination models. High quality rendering is too slow to be interactive.
In this paper, we extend the notion of light vector by computing it in 5D and we try to obtain an interactive high quality rendering with global illumination by merging the notion of light vector with the render cache approach.
