3.4.11  Superquadric Ellipsoid Object

There are a couple of facts about superellipsoids we should know. First,
we should not use a value of 0 for either Value_E nor Value_N. This will
cause POV-Ray to incorrectly make a black box instead of our desired shape.
Second, very small values of Value_E and Value_N may yield strange results
so they should be avoided. Finally, the Sturmian root solver will not work
with superellipsoids.

Any questions ?
