Constructor Detail

• Plane3D

  public Plane3D(Vector3D normal,
                 Coordinate basePt)

Method Detail

• orientedDistance

  public double orientedDistance(Coordinate p)

  Computes the oriented distance from a point to the plane. The distance is:

  • positive if the point lies above the plane (relative to the plane normal)
  • zero if the point is on the plane
  • negative if the point lies below the plane (relative to the plane normal)

  Parameters:

  p - the point to compute the distance for

  Returns:

  the oriented distance to the plane

• closestAxisPlane

  public int closestAxisPlane()

  Computes the axis plane that this plane lies closest to.

  Geometries lying in this plane undergo least distortion (and have maximum area) when projected to the closest axis plane. This provides optimal conditioning for computing a Point-in-Polygon test.

  Returns:

  the index of the closest axis plane.
