@mbrandt-art/lining

Started as a fork of @anvaka/streamlines.

Rewritten to expose more options and optimize for plotter art.

API

computeStreamlines(options)

Returns: { lines, d_arr }

import { computeStreamlines } from '@mbrandt-art/lining'

let streamlines = computeStreamlines({
  bbox: { left: -5, top: -5, width: 10, height: 10 },
  field(p){
    // custom field code goes here
    return {
      x: Math.cos(p.x),
      y: Math.sin(p.y)
    } 
  },
  tolerance: 0.05, // for line simplification
  seeds: [], // starting points
  forwardOnly: false,
  dSep: 0.5,
  dTest: 0.25,
  timeStep: 0.01,
})

streamlines.lines // ~> Array of lines [[x,y]]
streamlines.d_arr // ~> Array of SVG d strings
