photo-sphere-viewer.js是一个基于three.js的全景插件
1、能添加热点；
2、能调用陀螺仪；
3、操作简单，提供一张全景图片即可（大多数手机都可以拍摄）
官网：https://photo-sphere-viewer.js.org/
使用方法很简单，直接去官网参考example和api使用文档，github上下载源码即可。
建议不要找网上的，版本太老，api用法都不太一样了，功能也没有新版的完善。
1、直接访问全景图（移动端自动调用陀螺仪）
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>全景图基础版-自动调用陀螺仪/title> <link rel="stylesheet" href="libs/photo-sphere-viewer.min.css"/> <script src="libs/three.min.js"></script> <script src="libs/browser.min.js"></script> <script src="libs/photo-sphere-viewer.min.js"></script> <script src="libs/gyroscope.js"></script> <div id="viewer"></div> <style> /* the viewer container must have a defined size */ *{ margin:0; padding:0; } #viewer { width: 100vw; height: 100vh; } </style> <script>var viewer = new PhotoSphereViewer.Viewer({ container: document.querySelector('#viewer'), panorama: 'budi.jpg', plugins: [ PhotoSphereViewer.GyroscopePlugin, ], lang: { gyroscope : 'Gyroscope', }, }); // 如果是移动端 if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)) { viewer.once('ready', function(){ document.querySelector('.psv-gyroscope-button').click(); }); } </script></body></html>注意：Photo Sphere Viewer的陀螺仪必须在https下才能开启，否则无效！！！
2、使用iframe访问全景图
这种情况下存在跨域iframe问题，需要使用post message进行父子组件通信
(1)【父组件】iframe.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>全景图跨域iframe版-子组件</title> <style> *{ margin:0; padding:0; } html,body,iframe { width: 100%; height: 100%; } </style></head><body> <iframe id="iframe" frameborder="no" border="0" marginwidth="0" marginheight="0" src="https://xxx.xxx.com/vr.html" scrolling="no" allowTransparency="true"></iframe> <script> if (window.DeviceOrientationEvent) { window.addEventListener("deviceorientation", handleOrientation, false); // 组件iframe层 -- VR iframe层 } else { alert("您的浏览器不支持HTML5 DeviceOrientation接口"); } function handleOrientation(orientData){ var absolute = orientData.absolute; var alpha = orientData.alpha; var beta = orientData.beta; var gamma = orientData.gamma; // Do stuff with the new orientation data var val = { "act": "gyroscope", "val": { alpha: alpha, beta: beta, gamma: gamma } }; //获取iframe var ifr = document.querySelector('#iframe'); //iframe的路径 var url = 'https://xxx.xxx.com/vr.html'; ifr.contentWindow.postMessage(JSON.stringify(val), url); } </script></body></html>
(2)【子组件】vr.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>全景图跨域iframe版-子组件</title> <link rel="stylesheet" href="libs/photo-sphere-viewer.min.css"/> <script src="libs/three.min.js"></script> <script src="libs/browser.min.js"></script> <script src="libs/photo-sphere-viewer.min.js"></script> <script src="libs/gyroscope.js"></script> <div id="viewer"></div> <style> /* the viewer container must have a defined size */ *{ margin:0; padding:0; } #viewer { width: 100vw; height: 100vh; } </style> <script> // 接收消息 if(top !== self) { window.parent.postMessage("gyroscope", '*'); } window.onmessage = function(event) { var data = eval('(' + event.data + ')'); if (data.act === 'gyroscope') { window.deviceOrientation = data.val; } } var viewer = new PhotoSphereViewer.Viewer({ container: document.querySelector('#viewer'), panorama: 'budi.jpg', plugins: [ PhotoSphereViewer.GyroscopePlugin, ], lang: { gyroscope : 'Gyroscope', }, }); // 如果是移动端 if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)) { viewer.once('ready', function(){ document.querySelector('.psv-gyroscope-button').click(); }); } </script></body></html>
(3) 修改gyroscope.js （跟我需求一样的小伙伴直接复制替换即可）
