Blender Tutorial: Noise Advection with Geometry Nodes
Support us on Patreon: / entagma
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 vectors possible.
