Summary
You now know how to set up a OpenGL form where you can draw. But for now
play with this and I will come soon with my next article about OpenGL.
BTW: there is one thing I want to tell you and that is that you can put as
many glColor3f() functions between the glVertex3f() so
that all points get different colors really cool!!!
As you may notice we didn’t covered any basics for coordinates and this
will be my next article to really draw some figures and so.
