Direct Known Subclasses:

StereoFlyBehavior

public class DEMViewerFlyBehavior
extends FlyBehavior

Basically, this is the same type of behavior available with Sun's java3d demo. It is just condensed down into one file, rather than several inheritances. Movement is as follows. Left Click - move forward and backward, turn left and right Middle Click - look up and down, and roll Right Click - change elevation, and strafe left and right
