                         plausible soft shadows for complex dynamic scenes with rectangular 
                         light sources. The algorithms performance is mostly independent of 
                         the scene complexity and the source's size. Occluders and 
                         receivers do not need to be separated and no knowledge about the 
                         scene representation is required, making the method easy to use. 
                         The main idea is to approximate the occlusion in the scene with 
                         prefiltered occlusion textures. The visibility of the light source 
                         at a point in space is estimated by accumulating the occlusion 
                         caused by each texture, using a novel formula based on
