Question on setTransformGroup(TransformGroup)

[shochu]

I have an object type which extends BranchGroup. Something like shown below.

public class Model extends BranchGroup {
       Shape3D shape;

        public Model(){
            addChild(shape);
        }
}

I want to be able to translate this object around on the screen.  I thought I would be able to use setTransformGroup to do this.

Model myModel = new Model();
translateGroup = new TransformGroup();
Transform3D translate = new Transform3D();
translate.setTranslation(new Vector3f(10,10,0));
translateGroup.setTransform(translate);
myModel.setTransformGroup(myTransform);
addChild(myModel);

But this doesn't seem to be working.  Am I using the setTransformGroup incorrectly?  

If this is totally wrong then the other way I was thinking was to put in my Model class a TransformGroup for translating. Something like ...

public class Model extends BranchGroup {
       Shape3D shape;

        public Model(){
            addChild(TranslateGroup);
            TranslateGroup.addChild(shape);
        }
}

Do you think this would work? THanks for any advice.

Okay I fixed it by just adding a transformGroup to the Model Class which does the translation.
