To Smooth

Make your lines to curves

Chaikin's smoothing algorithm for polylines of any dimensions. Impressed by chaikin-smooth but, to-smooth is dimension generalized version of chaikin-smooth with iteration option.

You can use to-smooth instead of chaikin-smooth

Usage

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<Array<number>>

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
