Im currently using delphi using the opengl 1.1 specification unit file, and recently downloaded the 1.2 version. The major noticable difference between them were their file sizes. While version 1.1 was only around 72kb, 1.2 was well over 300kb.. But to my question, is version 1.2 actually an optimized version of 1.1? - Im not talking about (nor do i care about) the new extensions. Would it make some difference to the way my engine operates if i change to use 1.2, or would it be a decision based upon file sizes (in which case i''d choose 1.1). Thanks for any help guys. - Wav

I''d just try 1.1 unless you have a specific 1.2 function to use. I don''t understand why the size difference is so big. But why is 300K such a problem... even my crappy connection copes with that

Cheers for the advice Brett, yeah the 300k was ok to download, i was just having second thoughts about adding that 300k to my engine (even though it is reduced to around 30kb in the excutable).

The benefit to using Mike Lische''s opengl12.pas file is you no longer need to declare but the newest of extensions. He tried to make things as current as possible at the time. We''re now looking at numerous additional extensions with the introduction of Radeon and GeForce3 cards, but the multitexture extensions, amoung others, have been added.

Mike also added gl.h, glu.h, and opengl.pas into one file and created functions for handling extension management into one unit, thus it''s now 279k.

As fas as crunching into 30kb, the compiler only stores what you use.

Cheers,
Jason

Just to make things more interesting, OpenGL.org released the 1.3 specification yesterday...
