[JAVA3D] MouseRotate Question (very choppy)

[Nicholas Pappas]

        Hello all.

        I have a very simply BranchGroup, with a ColorSphere, and a MouseRotate
even listener.  When I start the program up everything work, but when I
move the mouse the object is *very* jerky in its movements.
        Is this possibly the result of something I did, or didn't, do?  Is it
just because the USB mouse is firing events so quickly that the rotation
jerks?  The second seems a little less likely.

        Here is my function creating the scene... nothing overly special.
"scene" is added to the SimpleUniverse after this is called.

  public void createSceneGraph(SimpleUniverse u) {
    scene = new BranchGroup();

    /** create a simple Shape3D node; add it to the scene graph */
    scene.addChild(new ColorCube(0.4));

    TransformGroup objTrans =
u.getViewingPlatform().getViewPlatformTransform();

    //KeyNavigatorBehavior keyNav = new
KeyNavigatorBehavior(u.getViewingPlatform().getViewPlatformTransform());
    KeyNavigatorBehavior keyNav = new KeyNavigatorBehavior(objTrans);
    keyNav.setSchedulingBounds(new BoundingSphere(new Point3d(),
1000.0));
    scene.addChild(keyNav);

    MouseRotate mouseRot = new MouseRotate(objTrans);
    mouseRot.setSchedulingBounds(new BoundingSphere(new Point3d(),
1000.0));
    scene.addChild(mouseRot);

    scene.compile();
  }
