## points_to_curve.js

// Calculates a curve that goes through a number of points.
// There are lots of mathematical approaches to do so
// (see: https://en.wikipedia.org/wiki/Cubic_Hermite_spline).
// The most commonly used seems to be the Catmull–Rom spline.
// My approch here is not intended to be a new general
// solution to this problem, but it should fit some geometrical
// and graphical needs. See
// https://hartmut-bohnacker.de/projects/points-to-curve
// for more explanation.

## angleDifference.js
// Returns the difference of two angles given in radians.
// The result is always between -PI and PI.

function angleDifference(angle1, angle2) {
	const TWO_PI = Math.PI * 2;
  let a1 = (angle1 % TWO_PI + TWO_PI) % TWO_PI;
  let a2 = (angle2 % TWO_PI + TWO_PI) % TWO_PI;

  if (a2 > a1) {
    let d1 = a2 - a1;

## crossingPoint.js
// Checks, if two lines (p1a to p1b) and (p2a to p2b) are crossing.
// Points are given as [x, y]. If inifinte1 is true, the first line
// will be continued before start and after end points. Same for line 2.
// Returns the crossing point as [x, y] or false if there is none.

// ATTENTION: this calculation is not completely precice in some cases!

function crossingPoint(p1a, p1b, p2a, p2b, infinite1, infinite2) {
	// vectors from start to end points
	let d1x = p1b[0] - p1a[0];
