In this coding challenge, I use the "superformula" to make a 3D "supershape" in Processing. This is part 4 of a multi-part series on superformulas, superellipses and supershapes
Article with information about the geometry and formulas for rendering supershapes.
Revi Ali's website with 3D geometries created by the superformula.
Wikipedia page with background and references on spherical coordinates.
