Basic Phyllotaxis in Blender Geometry Nodes
A fairly simple GN setup showing a basic phyllotaxis arrangement, as found in widely in nature. It is not intended as a complete, working solution, but rather as a prompt for further exploration.
The file includes a Bezier Curve, representing the profile of the 'petal' depicted, and a placeholder for the GN tree. There's also a camera, some environment lighting, and a very crude petal material.
If you can't afford or don't feel like downloading the file, the node tree can be re-built for free from the snapshots provided; the only important missing object is the petal profile, but this is just the default Bezier Curve with minor adjustments to its shape and orientation.
