The Geometry Setup wires the complete 3D spherical product formula entirely in math nodes

You find 2 Variation:

1) comes with 20 Presets for an easy start. A "Preset" Switch helps you to move between the different parameter

2) is the regular file where you can play with all parameter in the Geometry Node Modifier

* UV Sampling Grid — a mesh where X maps to θ (longitude) and Y maps to φ (latitude)
* Two full Superformula subgraphs — one for r1(θ), one for r2(φ), each with: m·ψ/4 → cos/sin branches → abs → power n2/n3 → sum → power 1/n1 → invert
* Division-by-zero protection via a MAXIMUM guard node
* Spherical product to compute final x, y, z
* Global Scale slider
