Hex Grid with Blender Material Nodes!

[Todd_Vance]

Here is the blend file with the node group. Note it is for Blender 4.0.

And here is an article I wrote explaining how I did it:

And some screen shots:

I learned material node editing form the Blender Material Nodes course, and I learned about Voronoi diagrams from https://link.springer.com/book/10.1007/978-1-4757-6568-7 (Sphere Packings, Lattices, and Groups by Conway and Sloane—yep, the same Conway who gave us Game of Life).

Nice. Is this a custom node with code or is it all done using only geometry nodes?

btw, look up Rhino CAD and Grasshopper, it’s all about algorithmic modeling. Grasshopper is node-based too and has been around for 20 years. And allows for custom code. Maybe you find inspiration or example code you can apply to Blender nodes.

No code, just material nodes.

I did this one too I think.

2022 Collab: Week 45 "Tooling: Geometric nodes" - VOTE CLOSED

This is the Blender collaboration 2022, week 45 challenge. Don’t be afraid to join, a lot of us are beginners. This is all to practice, have fun, learn, and get together. This week’s subject is “Tooling: Geometric nodes” . “Tooling: Geometric nodes" - Create an object or a scene of objects, using the geometric tooling of Blender. For example a mouse maze, geometric constructs, like buildings, and roads, … be creative in your subject, but try to experiment with geometric nodes. Subject select…

Have fun!

Cool. Well, the course is on my todo list

Nice, I really wish Blender would implement more grid shape nodes to easily create patterns like this.
I worked on one a few years ago during Nodevember and got this result:

The Node tree was a bit crazy:

Nice! I think I’ll enjoy this course, given that I have used Grashopper + Rhino CAD since 20 y’s.

Cheers,

Nice, I’ve only use Rhino a few times ( and only really to convert Rhino model to use elsewhere) but I’d love to look into Grasshopper and Blender addons Like Sverchok at some point to get more familiar with Parametric design tools. Erindale has been a big inspiration in that space for a while, but with Geo Nodes gettings so many updates, its hard enough to find time to keep up to date with vanilla Blender.
