如何创建3D动画立方体

<div id="container"></div>

#container {
  width: 400px;
  height: 400px;
  transform-style: preserve-3d;
  perspective: 1000px;
}

// 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.getElementById("container").appendChild(renderer.domElement);

// 创建立方体的几何体和材质
var geometry = new THREE.BoxGeometry(1, 1, 1);
var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
var cube = new THREE.Mesh(geometry, material);

// 将立方体添加到场景中
scene.add(cube);

// 设置相机位置
camera.position.z = 5;

// 动画循环
function animate() {
  requestAnimationFrame(animate);

  // 改变立方体的旋转角度
  cube.rotation.x += 0.01;
  cube.rotation.y += 0.01;

  // 渲染场景
  renderer.render(scene, camera);
}

animate();
