Re: gEDA-user: More GL stuff to test

[andrew whyte <ajwhyte@xxxxxxxxx>]

Just a quick note on perspective.  In my experience with 3D CAD
(solidworks) perspective is optional, and most skilled CAD designers
that I know work without it.  That means that parallel lines are
parallel on the screen.  (is this called orthographic? - well... its
the same idea as isometric projection mentioned above)

I'm no expert and its been many years since I have coded openGL, but I
think that there is a 'projection matrix' that can turn perspective on
and off...
