Karl:
I have never used clone. But I did use the SharedGroup. Here is how I used
them:
I first created a class extends SharedGroup where I have the geometry,
appearance, etc defined. Aware of that this is just a type of Group.
Then in the class that I need to plant the object of the SharedGroup, I
used the following code:
Vector3f treeTranslate = new Vector3f();
treeTranslate.set( x,
getElevationGrid().getRelativeElevation( x, z ), z );
Transform3D treeT3d = new Transform3D();
treeT3d.setTranslation( treeTranslate );
// treeTGT plant the object where you want it to be
TransformGroup treeTGT = new TransformGroup();
treeTGT.setTransform( treeT3d );
Link link = new Link();
link.setCapability(Link.ALLOW_SHARED_GROUP_READ);
... ... // set capability
link.setSharedGroup(shGroupObject);
// shGroupObject is the instance of the SharedGroup
