## Package org.apache.commons.math3.geometry.spherical.twod Description

This package provides basic geometry components on the 2-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 x^{2}+y^{2}+z^{2}=1.
