@turf/bezier

@turf/bezier

bezier

Takes a line and returns a curved version by applying a Bezier spline algorithm.

The bezier spline implementation is by Leszek Rybicki.

Parameters

• line Feature<LineString> input LineString
• resolution [number] time in milliseconds between points (optional, default 10000)
• sharpness [number] a measure of how curvy the path should be between splines (optional, default 0.85)

Examples

var line = {
  "type": "Feature",
  "properties": {
    "stroke": "#f00"
  },
  "geometry": {
    "type": "LineString",
    "coordinates": [
      [-76.091308, 18.427501],
      [-76.695556, 18.729501],
      [-76.552734, 19.40443],
      [-74.61914, 19.134789],
      [-73.652343, 20.07657],
      [-73.157958, 20.210656]
    ]
  }
};

var curved = turf.bezier(line);

//addToMap
curved.properties = { stroke: '#0f0' };
var addToMap = [line, curved]

Returns Feature<LineString> curved line
