Q #1: For what purposes is glCullFace? is the code faster when i disable backfaces or it is the same?
Q #2: For what purposes is the display list? Is it really faster than manually calling all the glVertex functions (and all the mess)? When it is better to use the display lists?
Q #3: Depends the speed of drawing on the near and far parameter in the glFrustum?
In my code i have set the far limit to 50 and then to 500 an there was no difference between the speed of drawing. (I have tried it with and without display list).
I believe that it an be faster but how?
