Junichiro Horikawa Demonstrates Using Houdini to Create an Ammonite, or Nautilus Shell Based on Fractals.

There are only a few things in this world that can’t be made better by a well-served fractal. Side Effects Houdini offers a great playground to work with mathematics, code, and design.
Parametric Designer Junichiro Horikawa covers how to make an Ammonite or Nautilus Shell design in Houdini using notation from a paper that includes the abnormal winding condition.

A Logarithmic Spiral is a key to forms the basis of the Nautilus shell. The Nautilus isn’t Junichiro Horikawa’s first tutorial that nerds out of fractals. Previously he had a look at creating a 3D Fractal-Based Mandelbulb transposing some numbers into Vex code in Houdini.
