All Implemented Interfaces:

Serializable, Cloneable, Runnable, AnimationControl, AVControl

public class DownRoundingAnimationControlJ3D
extends AnimationControlJ3D
implements Runnable, AnimationControl

DownRoundingAnimationControlJ3D extends AnimationControlJ3D to provide a different sampling behavior. Instead of nearest neighbor, the nearest sample LESS THAN the current value will be displayed.
