Class Sphere2D
java.lang.Object
org.hipparchus.geometry.spherical.twod.Sphere2D
- All Implemented Interfaces:
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.
