Hi, I''ve followed through lots of tutorials and papers on OpenGL lately as I''d really like to learn about it. It''s funny how easy it is for me to code with state machine. OpenGL IS easy. But, here''s the thing. Extensions and it''s support of 1.2 1.3 functionality is whats messing my head. I have gl.h, glaux.h (bah) and glu.h MS 95 implementations. That is OpenGL 1.1, naturally. Now, I wanted 1.2 and 1.3 functionality in my latest tests, but I was confused what to download to have that. I''ve downloaded this: http://www.uni-karlsruhe.de/~uli2/index.html , and it seems to work fine. But, c''mon, I somehow think I''m missing something. Is 1.2, 1.3 functionality in Nvidia''s driver (I use Geforce2), or what? I''m terribly confused by this. Is that file (extgl) all I need for 1.2 and 1.3 functionality, or do I need something else too? On the side note, I use Dev-C++ 4.1 for coding. I plan to move to MSVC 6 (or .Net) soon. And I was wondering what EXACTLY does Nvidia''s OpenGL SDK means to me for OpenGL coding if I can have all functionality of 1.3 through standard lib.

I used extgl.h for awhile, but found it was missing support for a few extensions I needed. So now I use glext.h from SGI. You can also download extension headers from the nVIDIA and ATI developer sites that should work better for you.

If I remember correctly, OGL 1.2 and up are available through your video card drivers, not as a separate download. So, get the latest drivers and ask the company if they are for OGL 1.3. Also, ask them (or OpenGL.org) for the headers you should include in your project.
