re: Piet Hein's SuperDuperEllipse




From:

http://www.forum.swarthmore.edu/news.archives/geometry.puzzles/article422.html

--------------------------

The super-ellipse has an equation like an ellipsoid but cubic
rather than quadratic, e.g., in a coordinate system with axes
parallel to the axes of the ellipse and with origin at the
center, x^3/a^3 + y^3/b^3 + z^3/c^3 = r^3.

Maybe you should try 'Excite' next time! :-)
