The second question I wanna ask is that how do I use lookAt()?
You must call invert() like this:
ct3d.lookAt(new Point3d(0, 0, 5f), new Point3d(0, 0, 0), new Vector3d(0, -1, 0)); tg.invert(); tg.setTransform(ct3d);
Btw. Are you sure -Y is upwards in your universe? Seem to be an unusual asumption.
Hope that helps Nikolai
