Library Patterns

Voronoi

Cells from random sites, coloured so no two neighbours match.

patterns.voronoi · v1 · renderer canvas

Result

90 cells · coloured by identity · 1.6 px borders

Every pixel is painted the colour of whichever of the 90 sites is nearest to it. The borders are drawn nowhere: they are the places where the nearest and second-nearest sites are the same distance away, which the renderer already knows because it measures both. Cell areas vary widely around their 6,000 px average — the sites are independent, so they clump, and a clump of sites means a cluster of small cells.

The token is the seed, so this link recomputes the result rather than looking it up. No database, and it works for as long as v1 does.

This page and /api/v1/g/patterns.voronoi run the same code. There is no private endpoint.
