David Kahl Demonstrates Using the Superformula in SideFX Houdini.

A new VEX Quicktip details how to work with the Superformular within Houdini’s VEX. David Kahl recently had a look into working with polar coordinates, covering the concepts and practical implementation in Houdini. The next logical step according to Kahl is to segue into Superformula. “The general concept is very similar to the polar coordinates,” Kahl says.

Instead of using aesthetic radius for circles, or a gradient radius like in a spiral, the superformula uses a math function to determine the range at any given point. “The formula creates a superellipse of a wide variety depending on the given parameters,” Kahl notes.
