It's surprisingly simple, it turns out.
First, you have to tag the OSG smart pointer type, as follows: ------------------- #ifndef REF_PTR_TRAIT_ #define REF_PTR_TRAIT_
#include <boost/python.hpp> #include <osg/ref_ptr>
namespace boost { namespace python { template <class T> struct pointee< osg::ref_ptr<T> > { typedef T type; }; }}
#endif -------------------
Then, in a BOOST_PYTHON_MODULE, you can write:
class_<Node, ref_ptr<Node> >("Node", init<>()) ;
You can of course add as many of the Node class's methods as desired.

What is wrong with the following code? I suspect I'm doing something silly, and I suspect the answer is obvious.

using namespace osg; typedef ref_ptr<Node> NodePtr;
using namespace boost::python;
BOOST_PYTHON_MODULE(NodePtr) { class_<NodePtr, pointee<NodePtr> >("NodePtr") ; }
Boost.Python knows Boost and TR1 smart pointers, not any others. If you are using any others (ref_ptr in this case I gather) then you need to make Boost.Python aware of it, I am not sure how, reading through the code might reveal how.
Ooo, impressively simple. That should be added to the docs (FAQ at least?).
