Helix Noise — divergence-free helical flow, grid-freeEvery particle is advected by field.sample(x,y,z) — a live, analytic sum of Beltrami modes,
no grid and no simulation. Three controls: spectral slope (size), helicity (handedness), phase
coherence (noise → structure). Colour is the genuine helicity density u·ω. Drag to orbit,
scroll to zoom.
Helix Noise — the whole field is HelixNoise.create({modes,slope,helicity,coherence,seed})
and one .sample() call per particle. See README.md for the API and how to embed it.
