Easy to use robust Delaunay triangulation

delaunay-triangulate

Triangulates a set of points into a Delaunay triangulation. This code works in arbitrary dimensions, and both in the server and in the browser.

Here are some in browser demos:

• 2D Delaunay triangulation
• 3D Delaunay triangulation

Example

var triangulate = require("delaunay-triangulate")

var points = [
  [0, 1],
  [1, 0],
  [1, 1],
  [0, 0],
  [0.5, 0.5]
]

var triangles = triangulate(points)

console.log(triangles)

Install

npm install delaunay-triangulate

API

require("delaunay-triangulate")(points[,pointAtInfinity])

Constructs a Delaunay triangulation over points

• points is a collection of points in Euclidean space.
• pointAtInfinity is a flag, which if set adds an extra point at infinity to give the spherical compactification of the triangulation. The index of the point at infinity is -1

Returns A list of cells representing the faces of the triangulation. These are triangles in 2D or tetrahedra in 3D.
