    chaikin-smooth

    stable

    Chaikin's smoothing algorithm for 2D polylines.

    var smooth = require('chaikin-smooth')
     
    var path = [ [0, 0], [25, 25], [13, 13] ]
    var smoothedPath = smooth(path)

    The result will be:

    [ [ 0, 0 ],
      [ 6.25, 6.25 ],
      [ 18.75, 18.75 ],
      [ 22, 22 ],
      [ 16, 16 ],
      [ 13, 13 ] ]

    Usage

    NPM

    smooth(path[, output])

    Performs the smoothing algorithm on the specified path, returning a list populated with the additional smoothed points. If the input path has a length of <= 2, the result will be a new array with the same points as the input.

    If output is provided, it will push the points onto the specified path instead of creating a new one. This is useful to build a smooth polyline out of several inputs, or to re-use arrays to avoid GC thrashing. If reusing, you should clear the path first to zero-length.

    Note: This uses a strict array test, so it is safe to use map and other array functions on it:

    var smoothedPaths = paths.map(smooth)
