Menampilkan Garis dan Segitiga dengan OpenGL

Program untuk membuat garis adalah:
glBegin(GL_LINES);
glVertex3f(0.2, 0.2, 0.0);
glVertex3f(0.8, 0.2, 0.0);
glVertex3f(0.2, 0.5, 0.0);
glVertex3f(0.8, 0.5, 0.0);
glVertex3f(0.2, 0.8, 0.0);
glVertex3f(0.8, 0.8, 0.0);
glEnd();

Program Lengkap untuk membuat garis adalah:
