hmm, I refer to "object" as runtime version of the "class" instance.
Anyway more to the point, I would specialize Vehicule from
either Group or TransformGroup. Extending Vehicule from Shape3D is out of
question since you mention that Vehicule is a -group- of shapes.
Which is best optimised ? I don't know, but it probably look simpler if
you extend it out of TransformGroup. I only hope that when I compile
my scenegraph Java3D does such optimisation for me.
