                                        Superparabola
                           pulseparabola
A sampler of curves in the superparabola family.  Note the pulse for large values of p.

We define superparabola as a parabola raised to a  positive power greater than or equal to zero.  Example:

equationparabola

                                        Superellipse
                              cuepellipse
A sampler of curves in the superellipse family.  Note the cusp for small values of p.
The superellipse, also known as the Lamé curve, is used in the following form for the cylinder footprint:

From prism to cylinder to half-cylinder to triangular slices of area formed on the "hoof."
