public final class FPS
extends javax.media.j3d.Behavior

This class implements a 'FPS measurer', that can be easily include in a java3D sceneGraph. In order to get this FPS measurer just add it to your 3D graph, then you will be able to see the FPS on the console and/or using a provided text2D object directly include in your scene.
