rectilinear-router v1.0.1

Rectilinear Router

Rectilinear router in typescript. This will help you find a rectilinear path between two or more points.

A rectilinear path is a path composed of straight lines and 90 degree turns, it is common to route this way for schematics or PCBs.

This uses rtms-ts under the hood for fast computation of the minimal rectilinear steiner tree.

Usage

import findRectilinearRoute from "rectilinear-router"

const route = await findRectilinearRoute({
  // terminals are points that the route must go through
  terminals: [
    [0, 400],
    [0, 200],
    [300, 0],
    [800, 800],
    [600, 1000],
    [500, 500],
    [200, 700],
    [700, 300],
  ],
})

// console.log(route)
;[
  { from: [300, 200], to: [300, 300] },
  { from: [500, 700], to: [500, 800] },
  { from: [600, 800], to: [500, 800] },
  {
    from: [0, 400],
    to: [0, 200],
    fromTerminalIndex: 0,
    toTerminalIndex: 1,
  },
  { from: [300, 0], to: [300, 200], fromTerminalIndex: 2 },
  { from: [800, 800], to: [600, 800], fromTerminalIndex: 3 },
  { from: [600, 1000], to: [600, 800], fromTerminalIndex: 4 },
  { from: [500, 500], to: [500, 300], fromTerminalIndex: 5 },
