three.js 物体放大

// 引入 three.js 库
import * as THREE from 'three';

// 创建场景
const scene = new THREE.Scene();

// 创建相机
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// 创建渲染器
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建一个立方体
const geometry = new THREE.BoxGeometry(1, 1, 1);
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

// 动画函数
function animate() {
    requestAnimationFrame(animate);

    // 放大立方体
    cube.scale.x += 0.01;
    cube.scale.y += 0.01;
    cube.scale.z += 0.01;

    renderer.render(scene, camera);
