photo-sphere-viewer.js实现全景图

摘要：
Photo-sphere-viewer.js是一个基于三个js的全景插件。1.可以添加热点；2.可以调用陀螺仪；3.操作简单，可以在官网上提供全景图片：https://photo-sphere-viewer.js.org/使用方法非常简单。只需访问官方网站参考示例和api使用文档，然后从github下载源代码。建议不要在网上查找。版本太旧，api用法不同，新版本中的功能也不完善。DOCTYPE html˃全景基本版-自动调用陀螺仪/title˃˃/*viewer容器必须具有足够的大小*/*｛margin:0；padding:0；｝#viewer｛width:100vw；height:100vh；｝varviewer=newPhotoSphereViewer.viewer；//如果是移动终端，如果{viewer.once；}注意：PhotoSphereViewer的陀螺仪必须在https下打开，否则无效！！！

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">

    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <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>
