Abstract

Though a lot of improvement has been made to hair rendering techniques in the recent years, realistic rendering of hair remains a challenge, especially in real time. In this paper, we propose a fast technique to approximate the shading of hair lighted by an environment map, direct lighting or a global illumination system, without having to render deep opacity maps or requiring additional artistic work.
