The real-time visualization of complex virtual environments across the network is a challenging problem in Computer Graphics. The use of pre-computed visibility associated to regions in space, such as in the Potentially Visible Sets (PVS) approach, may reduce the amount of data sent across the network. However, a PVS for a region may still be complex, and further partitions of the PVS are necessary. In this paper we introduce the concept of a Smart Visible Set (SVS), which corresponds to (1) a
