This is a support package for [@thi.ng/geom](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/geom). Current implementations partially based on [toxiclibs](http://toxiclibs.org) (Java) and Clojure version of [thi.ng/geom](http://thi.ng/geom). ## Status **STABLE** - used in production [Search or submit any issues for this package](https://codeberg.org/thi.ng/umbrella/issues?q=%5Bgeom-closest-point%5D) ## Related packages - [@thi.ng/geom-isec](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/geom-isec) - 2D/3D shape intersection checks - [@thi.ng/geom-resample](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/geom-resample) - Customizable nD polyline interpolation, re-sampling, splitting & nearest point computation ## Installation ```bash yarn add @thi.ng/geom-closest-point ``` ESM import: ```ts import * as gcp from "@thi.ng/geom-closest-point"; ``` Browser ESM import: ```html ``` [JSDelivr documentation](https://www.jsdelivr.com/) For Node.js REPL: ```js const gcp = await import("@thi.ng/geom-closest-point"); ``` Package sizes (brotli'd, pre-treeshake): ESM: 1.08 KB ## Dependencies - [@thi.ng/api](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/api) - [@thi.ng/math](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/math) - [@thi.ng/vectors](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/vectors) Note: @thi.ng/api is in _most_ cases a type-only import (not used at runtime) ## Usage examples One project in this repo's [/examples](https://codeberg.org/thi.ng/umbrella/src/branch/develop/examples) directory is using this package: | Screenshot | Description | Live demo | Source | |:-------------------------------------------------------------------------------------------------------------------------|:--------------------------------------------------------|:--------------------------------------------------------|:---------------------------------------------------------------------------------------------| | | Interactive visualization of closest points on ellipses | [Demo](https://demo.thi.ng/umbrella/ellipse-proximity/) | [Source](https://codeberg.org/thi.ng/umbrella/src/branch/develop/examples/ellipse-proximity) | ## API [Generated API docs](https://docs.thi.ng/umbrella/geom-closest-point/) - `closestPointAABB` - `closestPointArray` - `closestPointCircle` - `closestPointLine` - `closestPointPlane` - `closestPointPolyline` - `closestPointRect` - `closestPointSphere` - `closestPointSegment` - `closestT` - `distToLine` - `distToSegment` ## Authors - [Karsten Schmidt](https://thi.ng) If this project contributes to an academic publication, please cite it as: ```bibtex @misc{thing-geom-closest-point, title = "@thi.ng/geom-closest-point", author = "Karsten Schmidt", note = "https://thi.ng/geom-closest-point", year = 2018 } ``` ## License © 2018 - 2026 Karsten Schmidt // Apache License 2.0 --- _Source: https://npm.io/package/@thi.ng/geom-closest-point · Machine-readable twin of the npm.io package page.
