The Restricted Binary Space Partitioning Tree (RBSP Tree) is introduced as an acceleration structure for ray tracing. An RBSP tree is a Binary Space Partitioning tree in which the splitting planes are restricted to a set of planes determined prior to tree construction. The RBSP tree, with its ability to select the splitting plane from a set of several planes, forms a structure that wraps the object closely resulting in a reduction in the number of intersections and node traversals. We study th theoretical utility of such a structure for ray tracing.
