public class PerspectiveShapeTransformer
extends PerspectiveTransformer
implements ShapeTransformer

PerspectiveShapeTransformer extends PerspectiveTransformer and adds implementations for methods in ShapeTransformer. It modifies the shapes (Vertex, Edge, and Arrowheads) so that they are distorted by the perspective transformation
