A Geometry nodes setup to achieve a "Stem and Peel" spiral effect to any curve. Draw a curve, set the number of sides, and peel away !

This node tree transforms any curve (generated, edited or drawn) into a customizable beveled curve with sides folding and unfolding into spirals.

It comes with the full setup, labels and explanations.

Video demo here and here.

The setup is only one example of using this node tree, you can utilize your own custom curves, shape them and bevel them in the node setup to your desire, and apply your own material to it. (The generated UV Map is exposed to an Attribute, and accessible in the Shader Editor)

The number of peeling sides, the degree of their individual peeling is completely customizable.

Happy Blending !

This is one of the three spiral curve setups:

1.  The Peel - "Stem and Peel" spiral effect to any curve in Geometry Nodes (This file - Advanced !)

2. Unfold - Spiral Any Curve In Geonodes

3. The Curl - Unified Unfolding Spiral Setup In Geometry Nodes

An additional setup, creating actually seamless Curve UV Map for curves generated in Geometry Nodes can be found here.

NOTE

- (Since it is a concept demonstration, it is kept as simple as possible.) The GeoNodes trees are kept clean for easier readability and have detailed explanations. Everything is built from the base. The point of these setups is to provide a base core of the concept, node from node, instead of contracting all into node groups with exposed settings, which makes everything harder to read and dissect.

You can embellish, refine as you wish based on the core or realize your own ideas.

- Read the text description, it has a lot of useful info !

- If you are not adding a camera, be sure to disconnect the Principled Volume node in the Shader Editor (World section)
