setShape would need to be changed to be a virtual method to achieve this as its currently only implemented in the Drawable base class, here setShape is just a handle for setting the shape used for collision detection algorithms. I actual regret writing ShapeDrawable now, it was only ever intended to be quite and dirty way to visual a shape, and never a general purpose tool for visualising shapes that users actual want so its always falling short of people expectations. It's design doesn't lend itself to becoming a general purpose shape visualization tool either, rather its a dead end design that's used far too widely for its own or its users good. An alternative might be to just have a createGeometry(osg::Shape&) function that builds a geometry that given a shape. Or perhaps rewrite ShapeDrawable so it "is a" Geometry, or "has a" Geometry. Suggestions welcome.
