Implicit Visibility and Antiradiance for Interactive Global Illumination

A reformulated rendering equation that allows interactive global illumination computation using implicit visibility. This method shifts visibility to local iterations and stores directional "antiradiance" information, allowing an efficient GPU implementation.

A Theory of Locally Low Dimensional Light Transport

A theory of how the dimensionality of local light transport varies with patch area. This paper analyzes how rendering cost varies with patch size, deriving an optimal block size.
