留着以后查看用 osgEarth_Clamp 种树，碰撞检测，定位器locator，地形更新回调terrian callback osgEarth_clipplane 裁剪，使用osg :: ClipNode和osg :: ClipPlane对象基于可见范围进行裁剪。 当您要在禁用深度测试的情况下绘制几何图形，但又不想在地球上显示几何图形时，此技术很有用。 水平剪辑平面，关闭深度测试，关闭深度测试会导致镂空地球的效果，很炫 render-depth-test: false; osgearth_colorfilter 创建个选择不同颜色标准的框框，没运行起来 osgearth_computerangecallback 自定义地图块，控制分页数据的，优化效率之类的 osgearth_controls 界面上创建了几个控制面板，来控制地球旋转之类的，但是没起到控制效果 ControlCanvas* cs = ControlCanvas::getOrCreate( &viewer ); 控制画布与viewer连接 控制界面上有能拖动的小滑块 osgearth_createtile 在鼠标点击的地方的地面上创建一个tile瓦片，能扩展许多，但是瓦片没有设置碰撞检测，能用在一些点击反馈上，比如点到哪里那里会响应 osgearth_datetime 创建日期时间，左上角有一个可拖拽的小进度条
