- * Bounding Volume Splay Trees for storing object bounding boxes.
- * Each node's bounding box entirely contains the bounding boxes of the nodes
- * to its left, and is entirely contained by the bounding boxes of the nodes to
- * its right. Splay trees are used for the implementation, to bring commonly-
- * used objects (the most recent object which a ray has hit) near the root of
- * the tree for fast access. Object's bounding boxes are expanded as needed
- * when inserted into the tree: if they intersect an existing bounding box, they
- * are expanded to contain it.
