vue3项目中使用three.js

在Vue 3项目中使用Three.js，你可以按照以下步骤操作：

1. 安装Three.js：

npm install three

2. 创建一个Three.js组件：

<template>
  <div ref="threeContainer"></div>
</template>
 
<script>
import * as THREE from 'three';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';
 
export default {
  name: 'ThreeJsComponent',
  mounted() {
    this.initThreeJs();
    this.animate();
  },
  methods: {
    initThreeJs() {
      const scene = new THREE.Scene();
      const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
      const renderer = new THREE.WebGLRenderer();
      renderer.setSize(window.innerWidth, window.innerHeight);
      this.$refs.threeContainer.appendChild(renderer.domElement);
 
      const geometry = new THREE.BoxGeometry();
      const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
      const cube = new THREE.Mesh(geometry, material);
      scene.add(cube);
 
      camera.position.z = 5;
 
      const controls = new OrbitControls(camera, renderer.domElement);
      controls.enableDamping = true;
 
      this.scene = scene;
      this.camera = camera;
      this.renderer = renderer;
      this.controls = controls;
    },
    animate() {
      requestAnimationFrame(this.animate);
      this.renderer.render(this.scene, this.camera);
      this.controls.update();
    }
  }
};
</script>

3. 在Vue组件中引入并使用这个Three.js组件。

确保你的Three.js版本与你的项目依赖兼容，并且适合你的Vue 3项目。上面的代码是一个基本的Three.js场景设置，你可以根据自己的需求添加更多的3D对象和交互功能。
