js立体球体3d动画代码

// 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);

// 创建球体几何体和材质
const geometry = new THREE.SphereGeometry(1, 32, 32); // 半径为1，水平和垂直细分各32
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00, wireframe: true });

// 创建球体网格并添加到场景中
const sphere = new THREE.Mesh(geometry, material);
scene.add(sphere);

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

    // 球体旋转
    sphere.rotation.x += 0.01;
    sphere.rotation.y += 0.01;

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

// 开始动画
animate();

// 调整窗口大小时更新渲染器和相机
window.addEventListener('resize', () => {
    camera.aspect = window.innerWidth / window.innerHeight;
    camera.updateProjectionMatrix();
    renderer.setSize(window.innerWidth, window.innerHeight);
});
