Simple Triangle Drawing

        glBegin(GL_TRIANGLES);
        glColor3f(0.1, 0.2, 0.3);
        glVertex3f(0, 0, 0);
        glVertex3f(1, 0, 0);
        glVertex3f(0, 1, 0);
        glEnd();

• This gives you unlit, untextured, flat-shaded triangles
• You can also draw triangle strips, quadrilaterals, and general polygons by changing what value you pass to glBegin
