fix that code to handle that horse in array 3d matrix wireframe figure. here's errors "TypeError: projectedVertices[a] is undefined" and here's the code. it will be nice if you improve the overall handlage of all possible matrix array structure, so it will handle all possible variants of any wireframe models inside. output full code.: function render() {
  ctx.fillStyle = '#FFF';
  ctx.fillRect(0, 0, canvas.width, canvas.height);

  const rotY = rotateY(angleY);
  const rotZ = rotateZ(angleZ);

  const transformedVertices = vertices.map(vertex => {
    const extraterrestrialVertex = extraterrestrialTransformation(vertex, frequency, amplitude);
    const cx = extraterrestrialVertex[0] - offsetX;
    const cy = extraterrestrialVertex[1] - offsetY;
    const cz = extraterrestrialVertex[2] - offsetY;

    const rotated = transform(transform(transform([cx, cy, cz], rotX), rotY), rotZ);
