java.lang.Objectsim.portrayal3d.SimplePortrayal3D
sim.portrayal3d.simple.Shape3DPortrayal3D
public class Shape3DPortrayal3D
A simple portrayal for displaying Shape3D objects. You can find Shape3D objects, or CompressedGeometry objects (which you can make into a Shape3D in its constructor) all over the web.
By default this portrayal is not pickable, but you can change that. This is because complex Shape3Ds are somewhat flakey in pick handling.
Note that this is not the superclass of ConePortrayal, SpherePortrayal, etc. Those display, in Java3D-speak, "Primitives": bundles of shapes. No, we don't understand why either.

public javax.media.j3d.TransformGroup getModel(java.lang.Object obj, javax.media.j3d.TransformGroup j3dModel)
Portrayal3D
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.
getModel
in interface Portrayal3D
