Nanotechnology's shadow

The most popular techniques for interactive rendering of hard shadows are shadow maps and shadow volumes. Shadow maps work well in regions that are completely in light or in shadow but result in objectionable artifacts near shadow boundaries. In ...

Voxelized shadow volumes (VSVs) [Wyman 2011] are a discretized view-dependent shadow volume representation, but are limited to point or directional lights. We extend them, allowing dynamic volumetric visibility from area lights using imperfect shadow ...

Efficient shadowing algorithms have been sought for decades, but most shadow research focuses on quickly identifying shadows on surfaces. This paper introduces a novel algorithm to efficiently sample light visibility at points inside a volume. These ...
