JSPM – @thi.ng/geom-resample@0.2.51

Package Exports

@thi.ng/geom-resample

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 (@thi.ng/geom-resample) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

About

Customizable nD polyline interpolation, re-sampling, splitting & nearest point computation.

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

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

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 ],

//   [ 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 ] ]
