js全景

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

// 创建场景、相机和渲染器
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 加载全景纹理
const texture = new THREE.TextureLoader().load('path/to/panorama.jpg');
texture.wrapS = THREE.RepeatWrapping;
texture.wrapT = THREE.RepeatWrapping;
texture.minFilter = THREE.LinearFilter;

// 创建球体几何体和材质
const geometry = new THREE.SphereGeometry(500, 60, 40);
geometry.scale(-1, 1, 1); // 反转球体以正确显示全景
const material = new THREE.MeshBasicMaterial({ map: texture });

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

// 设置相机位置
camera.position.z = 0;

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    renderer.render(scene, camera);
}
animate();

// 添加交互控制（例如OrbitControls）
const controls = new THREE.OrbitControls(camera, renderer.domElement);
controls.enableDamping = true;
controls.dampingFactor = 0.25;
controls.enableZoom = true;
