Abstract:
1. A processor configured to render an indirect illumination image, comprising: a buffer restructurer configured to organize a reflective shadow map (RSM), rendered with respect to a reference view, into a plurality of unique sub-RSMs, each having sub-RSM pixels; an indirect illumination computer configured to employ interleaved sampling on said plurality of unique sub-RSMs to generate a plurality of indirect illumination sub-images; and a filter operable to smooth accumulated light values of said indirect illumination sub-images for subsequent interleaving into said indirect illumination image, wherein said organizing said RSM into said plurality of unique sub-RSMs comprises assigning each pixel of said RSM to a single sub-RSM so that each sub-RSM has a same resolution and number of said sub-RSM pixels as all other sub-RSMs.
