               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.",
