The clue to the difference is the name.... PolytopeIntersector uses a Polytope do the intersection tests, while a LineSegmentIntersector uses a LineSegmenet. A Polytope is convex hull built from a list of planes (that represent half spaces). A LineSegment is simple two vertices that define the line segment. I would encourage you to search the web for more indepth discussion of what a Polytope is and what it's used for.
