Natural Spirals

Generate natural spiral arrays in seconds — with live updates, instancing, and a clean finalize workflow.

Features

• Divergence Angle: Golden Angle by default; fully adjustable with a Parastichy Helper (set angle from P1/P2 spiral counts).
• Count & Direction: Precise instance count with clockwise/counter-clockwise toggle.
• Radius Controls: Start/End radius with a Radial Bias curve for organic spacing.
• Axial Growth (Z): Axial step plus Axial Bias for tapered stacks or cones.
• Scale & Taper: Global scale bias with Linear or Parabolic taper profiles.
• Phase & Aim: Global phase rotation and optional Point to Center orientation.
• Natural Variation: Position and rotation wobble (randomized) for non-uniform, lifelike arrangements.
• Non-Destructive Workflow: Create/Reset, Delete Array, and Finalize (join to a single mesh) operators.
• Instancing-First: Fast object instancing using the active object’s mesh data; source is hidden for edit and render.

Here's a quick (silent) video of me running through the features.

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.

Quick Start

1. Select any mesh object.
2. Open Sidebar → Natural Spirals.
3. Click Create Array and tweak parameters live.
4. Click Finalize to join instances into one editable mesh (optional).
