WebJan 1, 2016 · The binary space partition (for short, BSP) is a scheme for subdividing the ambient space \mathbb {R}^ {d} into open convex sets (called cells) by hyperplanes in a recursive fashion. Each subdivision step for a cell results in two cells, in which the process may continue, independently of other cells, until a stopping criterion is met. WebRecursive Partitioning.
