Create a Mesmerizing Double Pendulum With Houdini Vellum

Entagma shares some tips for creating a double pendulum in vellum.

The motion of two pendulums attached to each other is chaotic and exciting to the point of mesmerizing. Now you can simulate the effect of a double pendulum in Houdini thanks to Vellum. Entagma’s Moritz Schwind shows how to create one offering some tips while stepping through the process.

Setting one up is fairly straight forward, making use of the Vellum distance constraint to keep the relationship of the connected pendulums intact. The Vellum solver in Houdini uses a Position Based Dynamics system for cloth, hair, and grains. This approach is fast, reliable, and produces excellent results quickly.
