3d地球旋转 js

// 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);

// 加载地球纹理
const textureLoader = new THREE.TextureLoader();
const earthTexture = textureLoader.load('earth.jpg');

// 创建地球几何体和材质
const geometry = new THREE.SphereGeometry(1, 32, 32);
const material = new THREE.MeshBasicMaterial({ map: earthTexture });

// 创建地球网格并添加到场景
const earth = new THREE.Mesh(geometry, material);
scene.add(earth);

// 动画函数
function animate() {
    requestAnimationFrame(animate);
    earth.rotation.y += 0.005; // 地球旋转
    renderer.render(scene, camera);
}

animate();
