Description copied from interface: Portrayal3D

Provides a TransformGroup which defines the node(s) to place in the scenegraph. This is the Portrayal3D equivalent of Portrayal2D's draw(object, graphics, drawinfo) method.

You should hang your model off of the TransformGroup provided. You should not transform that TransformGroup in any way -- it is used elsewhere. Instead if you wish to transform your model (rotate it etc.) you should add your own additional TransformGroup as necessary.

The provided TransformGroup can be null; in this case you need to create and return the outer TransformGroup for the object. If the provided TransformGroup is non-null, you should modify it and return the same.

SimplePortrayals should assume the following contract: at the point that getModel(...) is called, the parentPortrayal will have already been set if it exists, else it will be null.
