An Optimized Soft Shadow Volume Algorithm with Real-Time Performance
(The Eurographics Association, 2003)
In this paper, we present several optimizations to our previously presented soft shadow volume algorithm. Our optimizations include tighter wedges, heavily optimized pixel shader code for both rectangular and spherical ...
Approximate Soft Shadows on Arbitrary Surfaces using PenumbraWedges
(The Eurographics Association, 2002)
Shadow generation has been subject to serious investigation in computer graphics, and many clever algorithms have been suggested. However, previous algorithms cannot render high quality soft shadows onto arbitrary, animated ...
