A Cloud of Shadows

Monday, 22 July 9:00 AM - 10:30 AM
Session Chair: Marc Olano, University of Maryland, Baltimore County

Imperfect Voxelized Shadow Volumes

Imperfect voxelized shadow volumes sample volumetric visibility from area light sources, allowing real-time rendering of volumetric shadows from complex lights inside homogeneous fog or dust.

Sub-Pixel Shadow Mapping

Sub-Pixel Shadow Maps are a simple and inexpensive alternative to classical shadow mapping, bringing high-quality shadowing capabilities into highly demanding applications such as video games, in which neither image quality nor speed can be compromised.

Lighting Technology of "The Last of Us"

How simple, directional representation of lighting can be used to efficiently solve some of the common problems with lightmaps in real-time applications: lack of specular highlights, discontinuity artifacts resulting from UV layout, or absence of believable shadows from dynamic objects.
