abstract = "This paper presents an algorithm for rapidly creating
and rendering soft shadows on a plane. It has the
advantages of rapid generation on current hardware, as
well as high quality and a realistic feel on a
perceptual level. The algorithm renders the soft shadow
to a texture. It begins with a hard drop shadow, then
uses the object's silhouette edges to generate
penumbrae in a single pass. Though the shadows
generated are physically inaccurate, this technique
yields penumbrae that are smooth and perceptually
convincing.",
