I mean that I know that the real perfect bounding sphere is computationally

But in many other cases (dynamic geometry) it must be computed each

If you need a very tight bounding sphere, you could write your own
NodeVisitor to create it. But changing OSG to compute and use tight
bounding spheres throughout would be a formidable redesign that could
take 2-4 engineering months to completely code and test, and while it
might improve culling in some cases, it would also harm performance in
other cases, so the net result would probably be a wash.
