Birefringence-Based Real-Time Rendering of Translucent Material

Abstract

In this paper, a new rendering method is proposed for translucent material in which birefringence is considered. We introduce birefringence (double refraction) to calculation scattering for translucent material rendering. A ray goes into two rays when it passes through a birefringence material. These shaded points are contributed by two refractive rays and these samples are selected in two refractive rays. We implement the method in translucent material rendering and good results are achieved.
