We present an algorithm that models stained glass in a physicallyrealistic manner. Stained glass is made by melting glass material with metal oxides that determine the color. Metal oxides are scattered in the glass, and we model it by distributing metal oxides in the volume defined by the glass. We render our stained glass model using a modified photon mapping. Our model is capable of modeling ...
