#cycloid #spirograph #epicycloid

I am sharing the process to create Spirograph Epicycloid curves using Blender Geometry Nodes, with the help of Internet and AI.

To convert Math Formula into nodes in geometry nodes, you can manually build the node tree but that could take forever, so there is a Math Formula addon that you can use for that.

In this episode, I am showing a basic node tree setup utilizing INDEX of POINTS value that plug into formula coordinate for XYZ points, which can generate something that you might be familiar with as Spirograph curves or epicycloid or hypocycloid curves.

Whenever you need some explanation you could try using AI like Meta AI to ask for explanation. But consider other AI like Gemini AI, ChatGPT 4o, Claude, Julius, etc.

Enjoy!
