Class StopLogicEngine

  • All Implemented Interfaces:
    StopEngine
    public class StopLogicEngine
extends java.lang.Object
implements StopEngine
    This contains the class to provide the logic for an animation to come to a stop. The setup defines a series of velocity gradients that gets to the desired position ending at 0 velocity. The path is computed such that the velocities are continuous
