说到3D，想必大家都能想到three.js，它是由WebGL封装出来的，接下来，我手把手教大家创建一个简单的3D页面

话尽在代码中，哈哈
大家可以复制代码玩一下

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <title></title>
    <style>
        * {
            margin: 0;
            padding: 0;
        }
    </style>
</head>

<body>

<script type="module">
    import * as THREE from 'https://unpkg.com/three/build/three.module.js'
    // 创建场景
    const scene = new THREE.Scene()
    // 创建相机
    const camera = new THREE.PerspectiveCamera()
    // 调整相机
    camera.position.z = 10
    camera.position.y = 2
    // 创建立方体
    const geometry = new THREE.BoxGeometry()
    const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 })
    // 网格
    const cube = new THREE.Mesh(geometry, material)
    cube.position.set(0, 3, 0)
    scene.add(cube)
    // 创建渲染器
    const renderer = new THREE.WebGLRenderer()
    // 调整渲染器大小
    renderer.setSize(window.innerWidth, window.innerHeight)
    // renderer中有domElement 是 canvas
    document.body.appendChild(renderer.domElement)
    // 添加网格地面
    const gridHelper = new THREE.GridHelper(10, 10)
    scene.add(gridHelper)
    // 让立方体转起来
    function animate() {
        requestAnimationFrame(animate)
        cube.rotation.x += 0.01
        // 进行渲染
        renderer.render(scene, camera)
    }
    animate()
</script>
