WGL_ARB_render_texture

OpenGL OpenGL: Advanced Coding
1

I just spent quite some time trying to find a wglext.h with the definition of the WGL_ARB_render_texture tokens and functions, but didn’t find any… so i’m just going to modify my own, but why isn’t there any updated version around ? The extension has been approved more than 6 months ago AFAIK !?

Hmm… wasn’t there a copyright notice at the top of this file?

Yes, what’s your point?

My point is self evident.

To quote ATI:

The tokens and prototypes required to utilize these extensions are found in the glATI.h and wglATI.h headers, which you can feel free to use in your own applications.

Not to overemphasize this issue, because I almost deleted my last post but forgot, but using a token in an application is not the same thing as publishing swathes of header information with the values that the tokens define.

Since these all exist in the extension registry I suppose this is a moot issue. I was just in a particularly pedantic mood.

Well, thanks, but my question was not what these tokens are :slight_smile: I very well know what they are, since as you said, you can find them in the extension registry. Sorry if my question was not clear.

I’d just like to know why the “official” wglext.h ( on www.opengl.org ) is not up to date ? Can we expect future updates or is it just “dead” ?
