You can traverse the scene using a nodevisitor and build a quadtree from
the drawables.
This is relatively complex, but Robert also pointed to the
osgForest-example which give you an idea.
One option is to decorate separable "groups" by adding them to a
osg::Group and let the osgUtil::Optimizer run with the SPATIALIZE_GROUPS
option.
This will help you only if you have separable drawables/geometries.
If you need to split geometries, you will have to indeed split by
testing against a plane (e.g. the middle plane of your potential volume)
and sorting the triangles (there is a mechanism inside the osg to
traverse the triangles) into distinct drawbles and put them in the
appropriate bin.

Can someone give me a hint how to start with that ?
Thanks in advance :)
