摘要
A method, system, and computer program product for reducing a boundary of a subspace in a binary space partitioning tree is provided. In one embodiment a space containing an object for which an image is to be rendered and displayed to a user is divided into subspaces. The boundaries of each subspace are recalculated to remove at least a portion of the dead space from within the subspace. The recalculation is performed by analyzing the spatial extent of the object or objects within the each subspace and recalculating the boundaries of each subspace to be coextensive with the boundaries of the object or objects within the subspace.
