The Unfold - Unified Animated Spiral Setup In Geometry Nodes

Geometry nodes-based spline manipulation - A folding and unfolding spiral setup example with instancing.

Video demo here and here.

A base curve line and a spiral is combined, then "combined", so it forms one continuous curve. The shape of the curve is achieved by A Float Curve node. The whole setup is completely procedural (The leaf's shape, the branch placement and so on).

The recombination of the spiral and it's base curve line ("stem") makes it possible to create the unfolding spiral, which can be shaped by its curve radius and treated and textured as one, continuous curve.

There are two blends included -

1. The full setup

2. A simplified version of a curve turned into unfolding spiral with a texturing example.

Happy Blending !

Compatible with Blender 3.6X and above.

The file is optimized for and rendered in Eevee (Render Viewport Animation). Of course, you can set up any renderer you wish.

This file is a part of a 3-part series on unfolding spiral curves

NOTE

-(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 node groups for easier readability and have detailed explanations. You can embellish, refine as you wish.

-(The setup should be opened in Blender 3.6X.)

(What's this ? A basically free Gumroad membership to access all blend files, materials, node setups and all the fun in the Codesignproject Gumroad page. A weekly growing selection of blend files, materials, models, Geometry Nodes setups and all. These setups are kept as simple as possible, concentrating on one concept, for readability and clarity, in order to make them as useful and easy to dissect them as possible.
