Two sheeted hyperboloid.


Mathematical description
A two-sheeted hyperboloid is a surface of revolution obtained by rotating a hyperbola about the line joining the foci. A two-sheeted hyperboloid with skirt radius a oriented along the z-axis has Cartesian coordinates equation:

                      x2    y2    z2
                     --- + --- - --- = -1.
