Functions

Function	Description
`createCircle(cx, cy, r, segments?)`	Regular n-gon disk
`createRect(x, y, w, h)`	Axis-aligned rect
`createRegularPolygon(cx, cy, r, sides, rotation?)`	Regular polygon
`createRing(cx, cy, outer, inner, segments?)`	Annulus (hole)
`createArc(…)`	Open arc polyline
`createStar(cx, cy, outer, inner, points?, rotation?)`	Star
`createKochSnowflake(cx, cy, r, iterations?)`	Koch flake
`createSponge(w, h, generators, thickness, smoothing, classes, seed?)`	Porous Voronoi sponge (`Group`)

Examples

Circle / star / snowflake

Shapes

Ring / arc

Ring and arc

Sponge

Merged Voronoi cells, Chaikin-smoothed, subtracted from a rectangle. Stroke the result as a fill. Lower classes → coarser blobs; higher thickness → thicker walls.

Sponge

const sponge = createSponge(100, 100, 40, 1.5, 2, 8, 19)
// stroke sponge.paths
