Image Title*: A Kummer surface is any one of a one parameter family of algebraic surfaces defined by a specific polynomial equation of degree four. The polynomial equation of degree four that describes a Kummer surfaces is: (x^2 + y^2 + z^2 - aa^2)^2 - \lambda *p*q*r*s = 0, where: :aa is any real number,
:\lambda\ = (3*aa^2 - 1.0)/(3 - aa^2),
:p = 1 - z - \sqrt{2}*x,
:q = 1 - z + \sqrt{2}*x,
:r = 1 + z + \sqrt{2}*y,
:and s = 1 + z - \sqrt{2}*y.
The family was described originally by Ernst Eduard Kummer in 1864. A Kummer surface has sixteen double points, the maximum possible for a surface of degree four in three-dimensional space. For the default case aa = 1.3, all these double points are real and they appear in the visualization as the vertices of five tetrahedra.
