Spherical geometry. Computer graphic of a spheri- cal harmonic function which has produced a torus- like shape. Spherical harmonics are often used to describe hybrid electron orbital shapes in molecules. A spherical harmonic function makes use of a spherical coordinate system. Spherical coordinates describe the position of any point in three-dimensional space by using a vertical angle, a horizontal angle and the direct-line distance from a reference point.
