Wojtek, I don't know. I just looked at the LOD::traverse method and saw that it called the node visitor getDistanceToViewPoint method, which for the CullVisitor calls the CullStack::getViewPointLocal method.
Ooops, looks like you'll need to override CullVisitor::getDistanceToViewPoint, not CullVisitor::getViewPoint. Also, the view point will need to be relative to the LOD object. I searched the entire OSG tree and only LOD and PagedLOD call getDistanceToViewPoint, so it should be pretty safe. Caveat - I've only looked at the code and haven't tried this.

Thats sounds like it something I might be able to do ;-). Do you know if changed viewPoint would affect other types of nodes apart from LOD ?
