Functions

Function	Description
`extractPerimeter` / `extractBoundary`	Exterior only
`extractHoles`	Hole paths
`densify(path, maxSegLen)`	Insert vertices
`removeSmallHoles(path, minArea)`	Drop tiny holes
`generateRandomPoints(path, n, seed?)`	Seeded interior samples
`generateRandomGridPoints(path, spacing)`	Grid filter
`pointsOnExterior` / `segmentsOnExterior`	Boundary samples / edges
`slice(path, a, b)`	Cut by infinite line through `a→b`
`centroidSplit`	Vertical cut through centroid
`dissolve(paths)`	`unionAll`
`intersectionPoints(a, b)`	Boundary crossings

Example — slice

Slice

const pieces = slice(createRect(15, 15, 70, 70), vec2(10, 20), vec2(90, 80))
