Syntax
struct FBspNode
Remarks
FBspNode defines one node in the Bsp, including the front and back pointers and the polygon data itself. A node may have 0 or 3 to (MAX_NODE_VERTICES-1) vertices. If the node has zero vertices, it's only used for splitting and doesn't contain a polygon (this happens in the editor).
vNormal, vTextureU, vTextureV, and others are indices into the level's vector table. iFront,iBack should be INDEX_NONE to indicate no children.
If iPlane==INDEX_NONE, a node has no coplanars. Otherwise iPlane is an index to a coplanar polygon in the Bsp. All polygons that are iPlane children can only have iPlane children themselves, not fronts or backs.
