three.js vr全景图

// 引入Three.js库
import * as THREE from 'three';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';

// 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 = 1;

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

// 加载全景图纹理
const textureLoader = new THREE.TextureLoader();
textureLoader.load('path_to_your_panorama_image.jpg', (texture) => {
    const geometry = new THREE.SphereGeometry(500, 60, 40);
    geometry.scale(-1, 1, 1); // 反转球体以正确显示全景图
    const material = new THREE.MeshBasicMaterial({ map: texture });
    const sphere = new THREE.Mesh(geometry, material);
    scene.add(sphere);
});

// 添加轨道控制以便用户可以通过鼠标交互
const controls = new OrbitControls(camera, renderer.domElement);

// 动画循环
function animate() {
    requestAnimationFrame(animate);
    controls.update();
    renderer.render(scene, camera);
}
animate();

// 处理窗口大小变化
window.addEventListener('resize', () => {
    camera.aspect = window.innerWidth / window.innerHeight;
    camera.updateProjectionMatrix();
    renderer.setSize(window.innerWidth, window.innerHeight);
});
