Voronoi Points Generator
Create deterministic 2D point distributions using Poisson disc sampling (even spacing), blue noise (perturbed grid), or random particles. Useful for procedural generation, spatial testing, and visualization.

What it does
The Voronoi Points Generator produces 2D point clouds in three spatial distributions: Poisson disc sampling (organic, evenly spaced points with a guaranteed minimum distance), blue noise (a perturbed grid), and random particles (unstructured scatter). Up to 1,000 points in a canvas of your dimensions, seeded for reproducible layouts.
Common use cases
- Procedural generation — Poisson disc is the industry-standard way to scatter trees, rocks, and spawn points that look natural without clumping.
- Voronoi diagram seeds — feed the points into a Voronoi/Delaunay library for region maps, cell shading, and territory generation.
- Sampling and dithering — blue-noise patterns for graphics techniques that want even-but-not-regular coverage.
- Visualization tests — point layers with known spatial properties for spatial-index and clustering code.
Settings
- Distribution type — Poisson disc, blue noise, or random particles (a preset for each).
- Point count — 1 to 1,000 points.
- Width / Height — the canvas, up to 10,000 × 10,000 units.
- Min distance — the spacing guarantee for Poisson disc sampling.
- Seed — identical seed + settings = identical layout.

Points are computed locally in your browser; nothing is uploaded — pure procedural geometry.
FAQ
Why does Poisson disc look so much better than random? Pure random scatter clumps and leaves voids (that’s what randomness looks like); Poisson disc enforces a minimum gap, producing the even, organic spacing forests and star fields actually have.
What’s blue noise, in one line? Even coverage with no low-frequency clumping — a grid that forgot to be a grid. Cheaper than Poisson disc, almost as pretty.
How do I get actual Voronoi cells? These are the sites: run them through d3-delaunay or any Voronoi library and the cells fall out. For terrain around them, see the Procedural Map and Perlin & Simplex tools.
