Description

This article describes how the map is put in a k-D tree, using only important features as splitting planes. A PVS is then computed on this k-D tree in the preprocessing step. At run-time the PVS is used as first culling, followed by a more accurate portal culling. The visibility is then cached to utilize frame coherency.
