<p>A geometric transformation useful for the positioning, orientation, and shape alteration of graphical objects is introduced. The form of its invocation in the language for interactive graphics (LIG) is described. The approach can easily specify complex transformations and functions effectively in combinations. Sample applications showing two styles of use and a description of the mathematics used to implement the transformation are included.</p>
