That would work for a static scene.

But you want to mark resources ready for release when nodes are 
removed from the graph dynamically. In most cases shared pointers 
(ref counting) would work, but if you allow "fractal" recursion 
then you will get cycles. (e.g. 
meshnode->scaleRND->rotateRND->stopIfTooSmall->meshnode )
