About

Customizable nD polyline interpolation, re-sampling, splitting & nearest point computation. This is a support package for @thi.ng/geom.

Also includes an implementation of Douglas-Peucker polyline / polygon simplification.

Current implementations partially based on toxiclibs (Java) and Clojure version of thi.ng/geom.

API

Generated API docs

import { resample, simplify } from "@thi.ng/geom-resample";

// resample polygon w/ uniform distance
const pts = resample([[0,0], [100,0], [100,100], [0,100]], { dist: 25 }, true)

// [ [ 0, 0 ], [ 25, 0 ], [ 50, 0 ], [ 75, 0 ],
//   [ 100, 0 ], [ 100, 25 ], [ 100, 50 ], [ 100, 75 ],
//   [ 100, 100 ], [ 75, 100 ], [ 50, 100 ], [ 25, 100 ],
//   [ 0, 100 ], [ 0, 75 ], [ 0, 50 ], [ 0, 25 ] ]

// simply polygon
// (epsilon = 0 only removes co-linear points, increase if necessary)
simplify(pts, 0, true)

// [ [ 0, 0 ], [ 100, 0 ], [ 100, 100 ], [ 0, 100 ] ]
