If I sounded smart, I had you fooled.
I don't think that BSP trees are the best data model for lava and water since we aren't trying to reduce the computation time of transforming from 3d space to 2d space. We just want to check an attribute of any specific point in 3d space. But I struggle with BSP trees, so maybe I'm just wrong. To me, it begs the question, "why did SOE use BSP trees for their water and lava?" Maybe it's a good way to go, I just think a 3d matrix is simpler and faster since you can check for lava or water without any traversals or transforms.
Maybe I should be quiet since, admittedly, I have 0 BSP experience other than that wiki you linked me (thanks).
