Computing Optimized Shadow Volumes for Complex Data Sets |
Abstract: In this article, we describe a method for computing the exact front cap geometry visible from a given static light source. This is the exact geometry that is visible from the light's point of view, and it is useful for calculating shadow volumes. Previous work has been done on this topic; however, most methods suffer from either infinte recursion (with complex polygonal models) or fail to solve for cyclically overlapping polygons. The method presented here also works for scenes that have intersecting polygons.

Self-Shadowing Characters |
Abstract: This article presents a projective texture approach, which enables self-shadowing of convex subsections of characters in real time. After breaking the character into convex subsections, the subsections are rendered into a texture with varying alpha values from teh point of view of the light source. When the character is rendered from the viewer's point-of-view, this texture is projected back onto the convex subsegments of the character, simulating the occlusion of each subsegment with respect to the light source. Being map based rather than stencil-volume based, this technique requires no additional work to be compatible with higher-order surface tessellation techniques.
Practical Priority Buffer Shadows |
Abstract: This article presents a set of techniques to improve the utility of "priority buffers". Along the way, we will explore other shadow techniques, and close by discussing how to create useful hybrid techniques.
