[2、在QT Creator导入相关的库](#2、在QT Creator导入相关的库)
1、环境配置
系统:windows10系统
QT:版本5.15.2 编译器:MSVC2019_64bit 编辑器:QT Creator
OSG版本:3.7.0 64位 为MSVC环境下编译
osgQt:为第三方编译的库,OSG因为版本不同已经不提供osgQt的封装。
osg-earth版本: 3.6.0
2、在QT Creator导入相关的库

一个是osg的库,一个是osgQt的库,一个是osg-earth的库。

//#include "osgshowwidget.h"
#include <osgEarth/Map>

#include <osgGA/CameraManipulator>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
// // 获取可执行文件的目录
QString exeDir = QCoreApplication::applicationDirPath();
QDir::setCurrent(exeDir);
//osgShowWidget w;
// w.show();
// 初始化osgViewer
// 初始化osgEarth
osgEarth::initialize();
osg::ArgumentParser args(&argc, argv);
// 创建Viewer实例
osgViewer::Viewer viewer(args);
// 使用相对于exe的相对路径来构建.earth文件的完整路径
QString relativeEarthFilePath = "Maps/ocean.earth"; // 请替换为你实际的.earth文件相对路径
QString earthFilePath = exeDir + "/" + relativeEarthFilePath;
// 请替换为你实际的.earth文件路径
osg::ref_ptr<osg::Node> earthNode = osgDB::readNodeFile(earthFilePath.toStdString());
if (!earthNode) {
std::cerr << "Failed to load .earth file: " << earthFilePath.toStdString() << std::endl;
return -1; // 如果加载失败,返回错误码
}
// 设置场景数据为加载的.earth文件
viewer.setSceneData(earthNode.get());
// 设置地球操控器
viewer.setCameraManipulator(new osgEarth::Util::EarthManipulator(args));
// 运行Viewer
return viewer.run();
//return a.exec();
}
运行结果:
4、运行过程中的问题
osg-earth是基于osg上的封装,osg又是基于opengl上的封装所以需要底层依赖库:
所以想要运行exe,需要把gdal381下的所有的dll文件都拷贝到exe可执行文件下,还有osg下的所有的dll文件,还有osg-earth下的所有的dll文件,包括
这个文件夹下的所有的dll文件。
由于需要的底层依赖库需要
这个是release模式的,在debug模式下就无法运行。会报错
由于我使用osg以及相关的库都是用的别人编译好的,我自己编译不成功,所以只能这样了。
