本文详细介绍了从初始化GDAL和curl客户端开始，经过shader及state配置等步骤，最终读取并解析.earth文件的过程。文章重点讲解了如何利用tinyxml进行文件加载，并将数据反序列化为osg::Node*。

回顾一下，经过各种初始化，gdal, curl客户端，shader,state,是否用memCache，通过各种osgDB::Options的过滤，网络还是本地文件，等等。终于读取了.earth文件，开始向readNode进行。

接下来用tinyxml加载，这里用osgEarth包装了一层。

剩下的都是tinyxml的相关内容了，没必要在这里面花时间了。直奔主题。

终于到osg::Node节点了

然后反序列化成osg::Node*

 

扩展dll在这里都是空的，继续向下

依照惯例，感谢@hankern 学习资源链接在https://blog.csdn.net/hankern/article/details/83933739 根据前面的内容，创建完插件了，加载了，现在就该解析了。 先定位到源码 看看类的定义和成员变量，大概就知道在干啥了 成员变量应该是支持协议，扩展和选项的集合。当然，里面还有其他类，暂时不写了。抄源码时抄过了，只写必要的。 跟下去，到doRead()了。 获取文件扩展名 判断扩展名小写是否为earth.

随着公司转入webgl，我要求调整到osg/osgearth工具，因为是c++方面的，特别是osg/osgearth源码可以深入下，以前光把视频教程看过，说白了就是简单二次应用，并没有深入下去，所以，趁此机会多读读osg/osgearth源码，根据工作和学习安排一半一半，正好就把一半时间搞osg/osgEarth 在此期间，有家ue4公司找我，我拒掉了，因为ue4的使用可以自学，深入下去还是要在...

sgEarth数据加载及组织解析 1．osgEarth的数据加载流程 由前文可知，用户可以使用osgEarth自己的earth文件，简单指定各种数据源，而不用关心数据如何渲染，便能在三维球上显示各种地形数据。本节，将会解读osgEarth如何解析earth文件，利用用户提供的数据源，来构建三维球上的各种地形。 图3.1所示是加载数据的整体流程，本节将就这四个步骤进行具体的解读。 图3.1 osgEarth数据加载整体流程 1.1 读取earth文件 osgEarth继承了OSG的插件机制，所以osgEarth提供了专门读取earth文件的osgdb_earth插件。通过查找并调用此插件，达到读取earh文件的目的。图3.2展示了查找读取earth插件的具体流程：

（它的_content是空的）；然后根据根json 上的children的个数， 再创建 N个 ThreeDTileNode（它的_content挂的是ThreeDTilesetContentNode）；这个N个ThreeDTileNode 可以理解为 就是子文件夹的个数；他的_content可以理解为 子文件夹上的主json。在下一次遍历中会判断是否有返回值；把根json在主线程加载完毕后；下一帧的时候，会调用。并没有一直遍历的接口；它创建的对象，是放在。代表每个文件夹下的主json；

如果比较懒，也可以不看这篇文章，网上应该有很多编译好的库。本人还是建议学会编译，因为其他人电脑上编译好的，可能在你的电脑环境上，出现这样那样奇怪的问题，所以，最好还是自己能够编译，学习源码也好、定位问题也好，都会方便很多。
