Abstract
A method in a graphics processor searches for a candidate reinsertion for each of a plurality of input nodes in a current bounding volume hierarchy (BVH), which would move the respective input node from an old parent to a new parent, and which would reduce the expected computational cost of searching the BVH for a ray intersection; and updates the current BVH with one or more selected reinsertions selected from among the candidates. In the search for candidate reinsertions, either or both of: a) the new parent is limited to being related to the old parent by an ancestor at no more than a predetermined number of hierarchal levels above the old parent, and/or b) the input nodes are limited to being at or above a hierarchical level a predetermined number of hierarchical levels below the root node.
