The associated ellipsoid with equal axes.


  

Mathematical description
The ellipsoid is a quadratic surface given by the equations:

                 x2    y2    z2
                --- + --- + ---  = 1,
                 a2    b2    c2
where the semi-axes are of lengths a, b, and c.
The models represents an ellipsoid with the same axis as in the Fresnel surface from Serie VI nr. 1.
