The Unfold is a Geometry Nodes setup demonstrating spline manipulation to create an animated folding and unfolding spiral. The system combines a base curve line and a spiral into a single continuous curve, shaped using a Float Curve node.

The procedural setup includes controls for leaf shape, branch placement, and curve radius. Because the stem and spiral are recombined into one curve, they can be treated and textured as a continuous object. The product includes two files: the complete setup and a simplified version demonstrating the texturing of an unfolding spiral curve. The node trees are uncontracted and include explanatory notes for study.
