                         densely occluded dynamic scenes where both the viewpoint and 
                         objects move arbitrarily. Our method works on a regular grid that 
                         represents a volumetric discretization of the space and uses the 
                         opaque regions of the scene as virtual occluders. We introduce new 
                         techniques of efficient traversal of voxels, object discretization 
                         and occlusion computation that strength the benefits of using 
                         regular grids in dynamic scenes. The method also exploits temporal 
                         coherence and realizes occluder fusion inobject-space. For each 
                         frame, the algorithm computes a conservative set of visible 
                         objects that greatly accelerates the visualization of complex 
                         dynamic scenes. We discuss the results of a 2D and 3D case 
                         implementation.",
