+AKBP contains one [[wikipedia:Binary_space_partitioning|BSP tree]] for each [[AKVA|BNV]] (the index of the root of the tree is stored in BNV). Such a tree is used to detect if a point is inside a BNV.
-:
+It should be noted that for convex BNVs the BSP tree degenerates to a list, only concave BNVs (and there aren't many of them) need a "real" tree.
