In Open3d:

import { Plane, Vector3d, Point3d } from 'open3d';

function main() {
  const plane = new Plane(Point3d.Origin, Vector3d.XAxis, Vector3d.YAxis);
  let point = new Point3d(100, 1000, 50000);

  while (true) {
    const cp = plane.ClosestPoint(point);
    const distance = cp.DistanceTo(point);
    if (distance === 0) return;
    else point = point.Add(new Vector3d(1, -1, -1));
  }
}

const start = Date.now();
