Class Sphere2D

java.lang.Object
org.apache.commons.math3.geometry.spherical.twod.Sphere2D
All Implemented Interfaces:
Serializable, Space
public class Sphere2D extends Object implements Serializable, Space
This class implements a two-dimensional sphere (i.e. the regular sphere).

We use here the topologists definition of the 2-sphere (see Sphere on MathWorld), i.e. the 2-sphere is the two-dimensional surface defined in 3D as x2+y2+z2=1.
