necesito que generes el código en javascript de un desierto con cielo azul con la biblioteca three.js

function desiertoAzul(){
  var scene = new THREE.Scene();
  var camera = new THREE.PerspectiveCamera(75, window.innerWidth/window.innerHeight, 0.1, 1000);
  var renderer = new THREE.WebGLRenderer();
  renderer.setSize(window.innerWidth, window.innerHeight);
  document.body.appendChild(renderer.domElement);
  var geometry = new THREE.BoxGeometry(1,1,1);
  var material = new THREE.MeshBasicMaterial({color: 0x00ff00});
  var cube = new THREE.Mesh(geometry, material);
  scene.add(cube);
  camera.position.z = 5;
  function render() {
    requestAnimationFrame(render);
    cube.rotation.x += 0.1;
    cube.rotation.y += 0.1;
    renderer.render(scene, camera);
  }
  render();
}
