public class FlythruRender
extends SurfaceRender
implements FlyThroughRenderInterface, FlyPathBehavior.Callback, com.sun.j3d.utils.behaviors.mouse.MouseBehaviorCallback, MouseListener, MouseMotionListener, MouseWheelListener

Virtual colonoscopy viewer. This class contains the static 'main' method to launch the application. This class is an Applet which means that it can be embedded in a browser or it can be attached to a MainFrame when executed as an application. The Applet contains a Canvas3D used for the 3D rendering of the colon surface data and for using the mouse and keyboard for maneuvering the view of the colon while moving through it.
