using namespace std;

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    if (!QGLFormat::hasOpenGL()) {
        cerr << "This system has no OpenGL support" << endl;
        return 1;
    }

    Tetrahedron tetrahedron;
    tetrahedron.setWindowTitle(QObject::tr("Tetrahedron"));
