We extend the shadow-volume algorithm so that every shadow-casting triangle can be associated with a transmittance texture, which dictates how much light can pass through the triangle at different locations. Our algorithm handles several layers of colored and semitransparent shadows. It allows efficient rendering of effects such as realistic shadows from leaves, fur, and colored glass. Source code is available online.
