  abstract =   "This paper describes a new algorithm that employs
               image-based rendering for fast occlusion culling in complex
               urban environments. It exploits graphics hardware to render
               and automatically combine a relatively large set of
               occluders. The algorithm is fast to calculate and therefore
               also useful for scenes of moderate complexity and
               walkthroughs with over 20 frames per second. Occlusion is
               calculated dynamically and does not rely on any visibility
               precalculation or occluder preselection. Speed-ups of one
               order of magnitude can be obtained.",
