osg学习笔记2, 命令行参数解析器ArgumentParser

ArgumentParser主要负责命令行参数的读取

#include <osgDB/ReadFile>

#include <osgViewer/Viewer>

int main(int argc, char **argv)

{

    //命令行参数读取

    osg::ArgumentParser arguments(&argc, argv);

    std::string filename;

    arguments.read("--model", filename);

    osg::ref_ptr<osg::Node> root = osgDB::readNodeFile(filename);

    osgViewer::Viewer viewer;

    viewer.setSceneData(root.get());

    return viewer.run();

}
