示例1: main

// OSG init
OSG::osgInit(argc,argv);
// GLUT init
int winid = setupGLUT(&argc, argv);
// open a new scope, because the pointers below should go out of scope
// before entering glutMainLoop.
// Otherwise OpenSG will complain about objects being alive after shutdown.
{
// the connection between GLUT and OpenSG
OSG::GLUTWindowRefPtr gwin = OSG::GLUTWindow::create();
gwin->setGlutId(winid);
