Sorry for this newbish question, but I can't find any information about it and I'm still getting used to OpenGL coming from DirectX. I found the specs for this extension and it's exactly what I need, but I can't figure out what I need to do to get it to recognize the new tokens. The specs say things like

COMBINE_ARB                                     0x8570   

Does this mean I just do #define COMBINE_ARB 0x8570 or is there some header that comes with everything defined for me? glext.h doesn't seem to have it, or my version is very out of date. Thanks for answering my questions on the other topic! I'm having much more fun with OpenGL than I ever did with DirectX . I can get straight to getting what I want on the screen without spending hours debugging my vertex buffers and device creation =).

Yes, there are include files for OpenGL extensions over at SGI's Extension Repository. The files you'll need are glext.h and wglext.h. They contain all the #defines required for OpenGL extensions, along with the extension function prototypes. I believe there's some issue with the updating of such files, and whether newer extensions have been included. I'm sure there's some information at the Repository about it...

An answer posted within 3 minutes. Hot damn I'm good...

Thanks, but it still won't recognize COMBINE_ARB or any of the other tokens. In glxext.h there are a bunch of syntax errors too...

Hmm that''s weird, the errors suddenly went away. Thanks!

Ok, I''m having troubles getting this to work right now . In DirectX I just used texture stage states but I can''t find the equivalent OpenGL ones. Basically I have a bunch of tiled textures, and then an alpha map stretched over the entire terrain that I want the tiled textures blended with. Help please?
