Abstract

In this paper we present an illumination model for rendering realistic stained glass which simulates the phenomenon of stained glass in real world. The optics for stained glass involves three basic physical mechanisms: diffuse light and specular highlight, Fresnel refraction, volume absorption; these dominate the appearance of stained glass. In this paper, we combine them to render realistic stained glass. Our approach avoids performing any expensive geometric tests, and involves no pre-computation; both of which are common features in previous work. The rendered stained glass images achieve excellent realism.
