hmm, the only problem i can see is:
OSG::NodeTransitPtr SceneGraphObjectNode::node()
{
return OSG::NodeTransitPtr(root);
}
TransitPtr behaves similarly to std::auto_ptr<>, including the odd and
confusing ownership transfer. It's only use is for a minor optimisation
of functions that _create_ objects (e.g. OSG::makeBox), never use it to
just return a pointer from a function. The way it is written, root
becomes a NULL pointer after calling node(), the pointer "transits" to
the caller.
The above should better look like:
OSG::Node* SceneGraphObjectNode::node()
{
return root;
}
Or, if you don't care about micro optimisations:
OSG::NodeRecPtr SceneGraphObjectNode::node()
{
return root;
}
Everything else looks ok to me. My guess would be that the problem is
somehow related to the issue above or in parts of the code you did not post.
Cheers,
Carsten
