  j3d.examples.particles.influences.Repulse

All Implemented Interfaces:

IExternalInfluence

public class Repulse
extends java.lang.Object
implements IExternalInfluence

Represents a point in space that repulses (accelerates away) particles from that point based on the distance between the particle and the repulsing point.
