Three.js如何实现反射效果

// 创建场景、相机和渲染器
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);

// 创建一个立方体
var geometry = new THREE.BoxGeometry(1, 1, 1);
var material = new THREE.MeshStandardMaterial({ envMap: cubeTexture });
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);

// 创建环境贴图
var cubeTextureLoader = new THREE.CubeTextureLoader();
var cubeTexture = cubeTextureLoader.load([
  'path/to/px.jpg', 'path/to/nx.jpg',
  'path/to/py.jpg', 'path/to/ny.jpg',
  'path/to/pz.jpg', 'path/to/nz.jpg'
]);

// 设置相机位置
camera.position.z = 5;

// 渲染场景
function animate() {
  requestAnimationFrame(animate);
  cube.rotation.x += 0.01;
  cube.rotation.y += 0.01;
  renderer.render(scene, camera);
}
animate();
