Abstract

See full text

A method for performing node traversal operations of a treelet-composed hierarchical structure includes allocating a queue for each of the plurality of treelets, each queue operable to store ray-states entering a respective one of the treelets. The method additionally includes determining that a ray-state exits a first treelet of the hierarchical structure and enters a second treelet of the hierarchical structure. The method further includes forwarding the ray-state entering the second treelet to a processing element for processing therein, wherein the queue allocated to store ray-states entering the second treelet is bypassed.
