To Smooth



Make your lines to curves



 

 



[Chaikin's smoothing algorithm](http://www.idav.ucdavis.edu/education/CAGDNotes/Chaikins-Algorithm/Chaikins-Algorithm.html) for polylines of any dimensions.

Impressed by [chaikin-smooth](https://github.com/Jam3/chaikin-smooth) but, to-smooth is dimension generalized version of [chaikin-smooth](https://github.com/Jam3/chaikin-smooth) with iteration option.

 

You can use to-smooth instead of chaikin-smooth

# Usage

```js

import smooth from 'to-curve'

import geojson from 'geojson.json'

if (geojson.geometry.type === 'LineString')

  geojson.geometry.coordinates = smooth(geojson.geometry.coordinates)

else if (geojson.geometry.type === 'MultiLineString')

  geojson.geometry.coordinates = geojson.geometry.coordinates.map(points => smooth(points))

```




 

# Docs

export default function

`smooth(points, options: {iteration, factor} = {iteration: 1, factor: 0.75})`

### points

same dimension point array like LineString Coordinates

- type - `Array>`

### options

- `iteration`

  - default - 1

  - description - if this increase, more smoother line return

  - iteration how many algorithm applied

- `factor`

  - default - 0.75

  - range - 0.5 - 1

  - do not have to change or assign
