How to use the @mathigon/core.chunk function in @mathigon/core

function createEdges(geometry: THREE.Geometry, material: THREE.Material, maxAngle?: number) {
  const obj = new THREE.Object3D();
  if (!maxAngle) return obj;

  const edges = new THREE.EdgesGeometry(geometry, maxAngle);
  const edgeData = edges.attributes.position.array as number[];
  const points = chunk(chunk(edgeData, 3).map(p => new THREE.Vector3(...p)), 2);

  for (const edge of points) {
    const curve = new THREE.LineCurve3(edge[0], edge[1]);
    const geometry = new THREE.TubeGeometry(curve, 1, LINE_RADIUS, LINE_SEGMENTS);
    obj.add(new THREE.Mesh(geometry, material));
  }

  return obj;
}
