Class Point3d

ffx.numerics.quickhull.Point3d

public class Point3d
extends Vector3d

A three-element spatial point. The only difference between a point and a vector is in 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.
