To calculate the potentially visible set (PVS) of leaves I have decided to use portals. This example calculates the non-arbitrary portals based on the partitioning planes in the BSP tree. I call them non-arbitrary because they are not added manually to the world data as they are in other editors such as MaxEd (the editor for Max Payne), in other words, if the world geometry changes the portals will be recalculated automatically. Next month I will release the calculation of the PVS but I have yet to decide on the final process.
