I suggest you to do a method that return the shape3D ....
For example
Class Polyhedron
{
.
.
.
Shape3D getPolyedron()
{
shape.setGeometry(myPolyhedron);
return shape;
}
}
So, in the second class you must use this:
Polyhedron polyhedron=new Polyhedron();
>
> BranchGroup group = new BranchGroup();
>
> group.addChild(polyhedron.getPolyedron());
>
> universe.getViewingPlatform().setNominalViewingTransform();
>
> universe.addBranchGraph(group);
