Ray tracing octree

WebGiven a pointer-based region octree, intersections of the ray with a node's bisecting planes are first evaluated to determine in which sub-octants the ray-node intersections may lie; a local ordering then determines the sequence in which these sub-octants should be examined so that the intersection closest to the ray's origin can be selected.
