Occlusion culling based on precomputed visibility information is a standard method for accelerating the rendering in real-time graphics applications. In this paper we present a new general algorithm that performs the visibility precomputation for a group of viewcells in an output-sensitive fashion. This is achieved by exploiting the directional coherence of visibility between adjacent viewcells. The algorithm is independent of the underlying from-region visibility solver and is therefore applicable to exact, conservative and aggressive visibility solvers in both 2D and 3D.
