Finds the affine hull of a point set

Package Exports

  • affine-hull

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (affine-hull) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

affine-hull

Computes the lexicographically smallest basis for the affine hull of a point set.

Example

var aff = require('affine-hull')

console.log(aff([
  [0, 0, 0],
  [1, 0, 0],
  [2, 0, 0],
  [3, 0, 0],
  [0, 1, 0],
  [0, 0, 2]
]))

Output:

[0, 1, 4, 5]

Install

npm install affine-hull

API

require('affine-hull')(points)

Computes a basis for the affine hull of the set of points points.

  • points is a list of points encoded by d-tuples of numbers

Returns A list of indices for the generators of the affine hull of the point set
