The Atypical shows how to simulate knotted cables with Vellum in Houdini.

Houdini’s Vellum is like softbody dynamics to the extreme. The system uses extended position-based dynamics to create anything from cloth, hair, balloons, and even, in the case of this tutorial from The Atypical, knotted cables.

The tutorial covers how to create and animate a knotted rope or cable using a Vellum simulation using Houdini and Redshift to render out the scene.
