Class HyperbolicTransformer

java.lang.Object
edu.uci.ics.jung.visualization.transform.MutableTransformerDecorator
edu.uci.ics.jung.visualization.transform.LensTransformer

All Implemented Interfaces:
BidirectionalTransformer, MutableTransformer, ShapeTransformer, ChangeEventSupport
Direct Known Subclasses:
HyperbolicShapeTransformer
public class HyperbolicTransformer extends LensTransformer implements MutableTransformer
HyperbolicTransformer wraps a MutableAffineTransformer and modifies the transform and inverseTransform methods so that they create a fisheye projection of the graph points, with points near the center spread out and points near the edges collapsed onto the circumference of an ellipse. HyperbolicTransformer is not an affine transform, but it uses an affine transform to cause translation, scaling, rotation, and shearing while applying a non-affine hyperbolic filter in its transform and inverseTransform methods.
