Yes, this is the scene graph approach. This is basically SVG, a
hierarchy of transforms, shapes and interactive nodes. A
retained mode version of Display Postscript. Although
OpenInventor has a more powerful model, perhaps (Coin3D is
freely available as a starting point).
Indeed, though OpenInventor is a 3D scene graph of course. I
don't think it's advisable to try and shoehorn 2D and 3D into one
system. For my money, web browsers have it about right - a
standardised DOM for 2D (albeit with the odd 3D css trick
available these days) and WebGL for the "real" 3D. Not only that,
but loads of people are already familiar with how they work.
