    int main(int argc, char **argv)
    {
        QGuiApplication app(argc, argv);
        Qt3DExtras::Quick::Qt3DQuickWindow view;
    
        // Expose the window as a context property so we can set the aspect ratio
        view.engine()->qmlEngine()->rootContext()->setContextProperty("_window", &view);
        view.setSource(QUrl("qrc:/main.qml"));
        view.setWidth(800);
        view.setHeight(600);
        view.show();
    
        return app.exec();
