The Surface Flow Swirl - Mesh Conforming Particle Flow Setup In Geometry Nodes With Surface Swirl

On Sale! by codesignprojects in Modifier Setups

A Noise distributed GeoNodes setup, constrained to a custom mesh surface. Additional control for distance from the surface and the style of the noise flow. 

Video demo  1, and 2.

In this additional version of the "Surface flow" setup, we add a bonus degree of movement - away from the mesh, along its normals. This way a fuzzy, warm and chaotic movement is created, which surrounds your mesh with floating and buzzing particles - while keeping them above the surface all times.

In this example the rotation speed is driven by audio. It, of course, could be driven by any value or manual keyframes too.

You can, of course, replace the main object and the particle objects with anything you wish to visualize.

The surface swirl effect is driven by a regular Noise texture, or - if you wish - you can use the provided Curl noise node group, which uses a "leapfrog integration" method to calculate the Curl and Gradient of the noise field, and creating nice, pleasing patterns.



(Since it is a concept demonstration, it is kept as simple as possible.) The GeoNodes trees are kept clean, the nodes are not contracted into nodegroups for easier readability and have detailed explanations.)

-Follow the instructions in the description to change the setup and fine tune it to your audio ! (You need to bake it to an Fcurve, fine tune it trough the Map Range nodes, and add keyframes to the material to control the emission glow and colors as you wish)
