Have either of you found a good way of writing a visitor for computing the bounding box that works on PagedLODs without children paged in? The only mildly acceptable method I've found is forcing a read on the first child then continuing traversal, but that's slow. I can also use the center and radius information when its available, but then I get bounding cubes.
You can't know what isn't there, you have to load the subgraph if you want its dimensions. The only other way might be to use UserData to store a precompute bounding box.
