getDistance

public double getDistance(Point3D point)

Description copied from interface: Shape3D

Gets the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.

Specified by:

getDistance in interface Shape3D

getDistanceSquare

public double getDistanceSquare(Point3D point)

plus

public Point3D plus(Vector3D vector)

minus

public Point3D minus(Vector3D vector)

contains

public boolean contains(Point3D point)

A point 'contains' another point if their euclidean distance is less than the accuracy.

Specified by:

contains in interface Shape3D

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Shape3D

isBounded
