Practical and Robust Shadow Volumes
Updated 3/18/02 with presentation slides from GDC 2002!
Using existing techniques, it can be quite difficult to render stenciled shadow volumes in a robust and artifact-free manner. The problem arises from the need to cap infinite shadow volumes at the near or far clipping plane. This paper describes a robust, artifact-free method of rendering stenciled shadow volumes that eliminates the problem of shadow volume capping. Further, the described technique works for all existing stencil capable hardware.
Some of the more difficult-to-find references from the paper are also included below:
