本人因为公司需求,需要做个VR全景功能,所以研究VR功能。在网上查询了一些资料以后发现krpano软件可以满足这个需求,果断学习之,如果大家有兴趣的话可以看下这些内容:
krpano360,http://www.krpano360.com 这个网站,我是从入门教程看到初级教程,在此先感谢下网站所有人“肥宗”哥,感谢他的无私分享,如果你看完了我说的内容的话,基本也了解了krpano基本功能。
分享下krpano的下载地址:https://pan.baidu.com/s/1oAaHjB0 密码:j6w8
关于注册码,可以加我微信或者留言给我,我私信给你。
好了,言归正传。下面我们开始讲解如何krpano功能化,首先我也是参考了cdsn的大神分享的文章,在此先谢谢“J_小浩子”的文章,地址:http://blog.csdn.net/change_on/article/details/77373644,有兴趣可以先看下。
说说如何功能话krpano的思路: 先来看下krpano的文件夹结构,根目录是vtour
这是最后生成好的文件,来说明下吧,panos-放置全景图或者缩略图文件夹,plugins-公用的插件文件夹,skin-皮肤以及一些配置文件夹,tour.html-主访问页面,tour.js-js文件用户html引用,tour.swf-用于flash引用,tour.xml-主配置文件。关于具体思路请参考小浩子大神的文章,本人不在这里重复阐述,说下最后我的结果文件夹内容:
这是最后的输出文件夹内容,其中plugin,skin和tour.html是公用的,target文件夹是每次上传都不同的。
主要是在大神们的思路和代码上进行了一些代码优化,分离了方法代码和执行代码,增加了背景音乐,底部logo和载入进度条等功能。
下面我们来看下具体的实现代码:
首先是:krpano类封装
/**

private String targetPath;
/**

private String loadingPath;
/**

*/
private String musicPath;
/**

*/
private String logoPath;
public String getKrpanoPath() {
return krpanoPath;
}
public String getSourcePath() {
return sourcePath;
}
public String getTargetPath() {
return targetPath;
}
public String getLoadingPath() {
return loadingPath;
}
public String getMusicPath() {
return musicPath;
}
public String getLogoPath() {
return logoPath;
}
public void setKrpanoPath(String krpanoPath) {
this.krpanoPath = krpanoPath;
}
public void setSourcePath(String sourcePath) {
this.sourcePath = sourcePath;
}
public void setTargetPath(String targetPath) {
this.targetPath = targetPath;
}
public void setLoadingPath(String loadingPath) {
this.loadingPath = loadingPath;
}
public void setMusicPath(String musicPath) {
this.musicPath = musicPath;
}
public void setLogoPath(String logoPath) {
this.logoPath = logoPath;
}
public String getTitle() {
return title;
}
public String[] getSceneTitle() {
return sceneTitle;
}
public void setTitle(String title) {
this.title = title;
}
public void setSceneTitle(String[] sceneTitle) {
this.sceneTitle = sceneTitle;
}
}
