This demo shows how to calculate the potentially visible set ( PVS ) of leaves in real-time. Unlike other methods that pre-calculate the PVS, this method uses the portals from the previous demo and the view frustum to find the minimum number of leaves visible given the current view. The full info can be found in the tutorial.
