Readme

alpha-complex
Alpha shapes are a generalization of Delaunay triangulations. Given a parameter alpha and a point set, they compute a simplicial complex which covers the point set in simplices whose circum radii are less than 1/alpha.
To see this in action, try out the demo
Example
var alphaComplex = require('alpha-complex')

var points = []
for(var i=0; i<100; ++i) {
  points.push([Math.random(), Math.random()])
}

console.log(alphaComplex(0.1, points))
Install
This module works in node.js/iojs/browserify and supports point sets in any dimension.
npm i alpha-complex
API

var cells = require('alpha-complex')(alpha, points)

Constructs the alpha complex of the given set of points.
  • alpha is the curvature of the alpha complex
  • points is a list of points encoded as arrays

Returns The alpha-complex of the point set.
