Abstract
Directional light maps allow to display globally illuminated static scenes with soft glossy surfaces at interactive frame-rates. They store the spatially and directionally varying incoming light at a surface in form of textures for a global set of incoming light directions. The directional light maps can be generated in a photon tracing preprocessing step. During a walkthrough they are used to render the globally illuminated surfaces with graphics hardware.Additional Files and Images
