| summary |
The authors take a pragmatic approach to shadowing and describe an algorithm that combines an existing shadowing method with a popular visible surface rendering technique, called a 'depth buffer,' to generate soft shadows resulting from light sources of finite extent. Their method extend Crow's shadow volume algorithm to produce multiple shadows overlapped to yield the characteristic soft edges of a shadow penumbra |
