【three】three.js实现3d动画

<script setup>
import * as THREE from "three";
import { OrbitControls } from "three/examples/jsm/controls/OrbitControls.js";

// 创建场景
const scene = new THREE.sence();
// 创建相机
const camera = new THREE.PerspectiveCamera(
  45, // 视角大小
  window.innerWidth / window.innerHeight, // 宽高比
  0.1, // 最近距离
  1000 // 最远距离
);
// 相机位置xyz
camera.position.set(5, 5, 26);

// 创建渲染器
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
//  画布追加到body
document.body.appendChild(renderer.domElement);
// 相机看向哪里默认为原点
camera.lookAt(0, 0, 0);
// 创建模型
let geometry = new THREE.BoxGeometry(1, 1, 1);
// 创建材质
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
// 创建网对象
const plane = new THREE.Mesh(geometry, material);
// 将网格添加到场景中
scene.add(plane);
// 创建控制器
const controls = new OrbitControls(camera, renderer.domElement);

// 渲染
const render = () => {
  controls.update();
  requestAnimationFrame(render);
