Actually I have overloaded PagedLOD to make some custom code into the
traverse, and particularly to handle intersection visitors a specific way
for my apps (by doing intersections only with some nodes and things like not
doing it every time...). So when converting my app to use the new
IntersectionVisitor I had some surpises :).
I think I am not the only one using a custom PagedLOD and having the
intersection visitor completely skipping it may be problematic. I will make
some change the less intrusive as I can and I will submit it. :)
Or if you have any suggestion on how to do my specific traverse code without
having to modify the IntersectionVisitor I would grantly appreciate.
