Natural Spirals (Phyllotaxis Arrays)

Impression Sunrise in Modeling


Parastichy Helper Tip

To avoid “spokes” (straight arms), choose consecutive Fibonacci counts for P1/P2 — e.g. 5/8, 8/13, 13/21, 21/34, 34/55, 55/89. These pairs are coprime and drive the divergence angle toward the golden angle (~137.5°), which strongly suppresses radial banding caused by simple fractions of 360°.

  • Small arrays (<150 instances): 13/21
  • Medium (150–400): 21/34
  • Large (400–1000): 34/55
  • Very large (>1000): 55/89

Tip: If you still see arms, bump to the next Fibonacci pair or nudge the angle by ±0.2–1°. Avoid small, simple ratios (e.g. 1/2, 1/3, 2/5) — they align points into visible rays.
