在 Three.js 中旋转天空盒

我使用以下方法创建了一个天空盒:

I have a skybox created using:

skybox_path = 'images/skybox_images/';
skybox_name = 'Stars_2';

var urls = [
            skybox_path + skybox_name + '_right1.png',
            skybox_path + skybox_name + '_left2.png',
            skybox_path + skybox_name + '_top3.png',
            skybox_path + skybox_name + '_bottom4.png',
            skybox_path + skybox_name + '_front5.png',
            skybox_path + skybox_name + '_back6.png'
          ];

var cubemap = THREE.ImageUtils.loadTextureCube(urls); // load textures
cubemap.format = THREE.RGBFormat;

var shader = THREE.ShaderLib['cube']; // init cube shader from built-in lib
shader.uniforms['tCube'].value = cubemap; // apply textures to shader

// create shader material
var skyBoxMaterial = new THREE.ShaderMaterial( {
  fragmentShader: shader.fragmentShader,
  vertexShader: shader.vertexShader,
  uniforms: shader.uniforms,
  depthWrite: false,
  side: THREE.BackSide
});


// create skybox mesh
var skybox = new THREE.Mesh(
  new THREE.CubeGeometry(1000, 1000, 1000),
  skyBoxMaterial
);

scene.add(skybox);

这很好用，但是我现在希望在动画循环中旋转天空盒.

This works fine, however I now wish to rotate the skybox within the animation loop.

如果我使用:

skybox.rotation.x += 0.01;

在渲染循环中，天空盒立方体会旋转，但纹理不会.立方体移动时，我得到了一个非常有趣且富有洞察力的效果，但纹理保持固定，但这不是我想要的效果，我希望纹理与立方体一起移动.

within a render loop, the skybox cube rotates, but the textures don't. I get a very interesting and insightful effect with the cube moving but the textures remaining fixed, but this isn't my desired effect, I'd like the textures to move with the cube.
