Umm, I think I found my own answer. - Subclass PolytopeIntersector to get access to the _polyTope member - transform this PolyTope by the inverse camera projection matrix to put it into world coords - When processing the Node, get the Node's bounding sphere, and transform that by the Intersection matrix into world coordinates - use the containsAllOf() method of the Polytope
