Direct Known Subclasses:

QuadTreeAwareCollisionPoint

public class CollisionPoint
extends Point
implements CollisionObject, PositionChangeListener<CollisionPoint>

An implementation of Point that allows for interpolation. Game objects can use this class to move around the game world and retrieve the appropriate rendering coordinates during render phase.
