Noise Advection with Geometry Nodes

Advecting points through vector fields is often handy for different purposes. It can be used to visualize noise fields or vector volumes or just to create some beautiful abstracted graphics. Follow Manuel in this tutorial, while he hacks Geometry Nodes to make iterative advection along […]

Giving Birth Using Vellum

Sometimes we get the weirdest questions. And we’re quite thrilled about them! This time our friend Patrick (https://www.altshift.de/) approached us with a.. let’s call it special Vellum setup and some questions about how to make all Elements interact properly and animate them. Resulting in whatever […]

No VEX Houdini: Organic Modelling Using Winding Numbers

Continuing our “No VEX Houdini” tutorials, Mo covers implementing a very clever technique to model organic surfaces using a mesh’s winding number, as presented in this thread on Twitter by Daniel Piker. In this quick (sub 10 min) tutorial, Mo will use one of Houdini’s […]

VEX in Houdini: Space Colonization

Branching growth is fascinating as it has a lot of hidden structure to it and is very intricate. Many methods have been proposed over the years to model branching structures, like trees. One algorithm that is particularly beautiful and simple is the “Space Colonization” algorithm, […]
