[Resolved][VB.NET preferably]BSP

Edit: Figured it out.

Does anyone have any good (Read: simple) tutorials on how to create and use a BSP, preferably in VB.NET?

Before you say I'm a n00b...
I've got this to render using an Octree but it's not very efficient as I need a large number of nodes to test (using an occlusion query) in a large indoor enviroment. Therefore, I need a fairly accurate visibility system. If I'm just looking at a flat wall, 1 face, I wouldn't want more than 20 faces rendered. I'm going to use it for static polygons. Also, the way my maps are imported, there is one giant list of triangles (Tri-fans but converted to a large triangle list).

So, anyone?

Well, I've got a BSP made, now I just need to figure out how to use it for "Hidden Surface Removal".

Any ideas?
