红胖子(红模仿)的博文大全：开发技术集合（包含Qt实用技术、树莓派、三维、OpenCV、OpenGL、ffmpeg、OSG、单片机、软硬结合等等）持续更新中…（点击传送门）

OSG、OSGEARTH三维开发专栏

前言

  本篇非常麻烦，博主用QtCreator作为IDE，因为Osg3.6.3放弃对osgQt的支持，集成起来比较繁琐。

前提

  基于前面三篇的基础上，才可以进行本篇。

Demo演示：Qt5.15.2+OSG3.6.3+OsgEarth3.1的QtCreator下的msvc2019x64版本

Demo运行程序下载

  QQ群：1047134658（点击“文件”搜索“osgEarth v1.0.0”，群内与博文同步更新）

OsgQt下载

  OsgQt地址：https://github.com/openscenegraph/osgQt
  QQ群：1047134658（点击“文件”搜索“osgQt”，群内与博文同步更新）

osgQt编译

步骤一：下载解压

步骤二：CMake配置

步骤三：CMake配置添加osg环境

步骤四：CMake配置添加Qt环境  

步骤五：CMake修改CMakeLists文件内容：

  
  还是出现错误：
  
  检查，并未发现错误
  
  继续深入    有一个路径填错了：  
  过了，继续配置：
  

  
  填入其他Qt路径：
  
  

步骤六：配置通过

步骤七：生成成功

步骤八：打开工程，进行编译

  
  编译各种问，尝试过多次后放弃，看其他博客是可以的。
  
  （后面的复杂，博主直接修改源码开始移植过去，直接加入工程方式，过程比较艰难，如果能编译好osgQt是最好的，改源码问题较多，需要的可联系博主获取，但是不免费，尊重劳动成果，禁止白嫖）
