Hello Robert, I use your technique based on osg::ComputeBoundsVisitor (starting from the J-S example).
osg::ComputeBoundsVisitor cbbv; root->accept(cbbv); osg::BoundingBox bb = cbbv.getBoundingBox(); It works very well for what I want.

This is exactly what you need to use if you want a tight bound on the subgraph. I believe Gordon's example pre-dates the the existance of ComputeBoundsVisitor and isn't as general purpose as the visitor now in the core OSG.
