is chapter presents soŸ shadow methods that are based on creating the geometryfor the penumbra regions rather than purely relying on images of the scene

6.1 IntroductionWhile exploring various aspects of computing shadows in the previous chapters,

We have seen in Chapter 3 that image-based hard shadows are prone to aliasing.

in this chapter, we will concentrate on sampling error

even though shadow algorithms have been around for almost as long as computer graphics itself, robust and efficient hard-shadow generation is still not a solved problem. while geometry-based algorithm...

over the last years, many contributions have been made in the field of shadows, and many have found their way into computer games. but at the time of this book’s writing, even though we have come a lo...
