This is just a quick little implementation of Delaunay Triangulation in JavaScript. It was mostly ported from Paul Bourke's C implementation, but I referenced some bits from another JavaScript implementation and rewrote a bunch of things in ways more amenable to fast JavaScript execution.
Essentially, you pass Delaunay.triangulate a list of vertices (which should be a bunch of two-element arrays, representing 2D Euclidean points), and it will return you a giant array, arranged in triplets, representing triangles by indices into the passed array. (This representation is a little bizarre, but object allocation is too slow for this library's original use case. Yes, really.)
To the extent possible by law, I have waived all copyright and related or neighboring rights to this library.
- @yahiko00 has released a TypeScript interface that may be useful if you are trying to access this library from TypeScript.
