Umm... its called OO programming, nodes can't be everything, you break up the classes to fit the functionality they deliver.

Thanks again, Robert.
One more quick question regarding the use/purpose of MaxtrixTransforms. Is
there a reason why the transforms for a node are separate from the Node*
class? The reason I ask is that I'm finding myself using a MatrixTransform
above many of my objects (static or otherwise), but not anywhere else. Are
there other intentions or advanced uses for the MaxtrixTransform class which
better demonstrate/explain the separation?
Thanks again for your advice. If I have something worth sharing regarding
the physics integration, I'll post it.
Cheers
E.
