Image Description, by
My colleague came up with an idea for shadow volume extrusion - if you want
to use simplified mesh for the volume and have self-shadowing - extrude the
frontfaces, not the backfaces!
The image on the top shows "conventional" shadow volume, where backfaces are
extruded. The bottom image has frontfaces extruded.
More on this technique and a small demo is at
