If you''re using a display list, then you can call it unlimited times and it won''t slow the program down right? Thanks

Well, I think display lists are used to speed it all up a bit, but it will still cost you some cycles.

With display lists, you generate precalculated data. For instance: if you need a sqrt() to normalize your normals before giving them to glNormal(). After using the display list OpenGL only "calls" glNormal and no more speed loss on sqrt...

Sorry, it''s a bit hard to explain, maybe someone else can do a better job...
