Class Point3d

java.lang.Object
  quickhull3d.Vector3d
      quickhull3d.Point3d

public class Point3d
extends Vector3d

A three-element spatial point. The only difference between a point and a vector is in the the way it is transformed by an affine transformation. Since the transform method is not included in this reduced implementation for QuickHull3D, the difference is purely academic.
