 polygon intersection
 Connected component and simple polygon intersection searching To traverse the HTE, we look first to polygons in the internal bounding volumes and deal with external boxes only when no ray-polygon intersection is found in internal nodes. We propose to use the expected area of polygon intersection for estimating the answer. This value is computed using the expected area of polygon intersection. Since the polygon intersection calculations described above are so simple, bounding volumes should contain collections of polygons.
