 I wrote the recalcBSphere method, and the comment, but was
not the original author of the VrmlNodeLOD class. Well, I
definitely wrote the code, and I think I wrote that comment.
It's been a while, but it  sure reads like something I
would write. Abject apologies if it was somebody else.

 That would be good.

 Yes, I had the same problem. Thus the current code :-)
At the time I wrote it, I'm pretty sure I was thinking
that you'd need a pre-render-traversal step that updated
each LOD based on the current viewer position. You can't
really do it during the render-traversal, because you
might accidently cull something that was about to become
visible because of an LOD change. I think. It was a while
back. Does that sound right?

 Double checking, yeah, I think that's about right. Hey,
didn't all the Nodes used to be in their own file? That
sure made it a lot easier to find things.
