Hi, Thanks for the tips. I know the planes' orientations need to be right. I assumed that by creating the Polytope from a BoundingBox that they would be, and when I inspect the values I think they're correct. I did try flipping them all in case I was wrong about the orientation, but that didn't help.
I meant to say that I did set a read callback on my PagedLODs. The callback works just fine for rendering, but maybe there's something weird about it when it comes to intersection visitors. I'm generating traces now to see how the LineSegmentIntersector and PolytopeIntersector differ. Thanks again.
