I realized that there is still a bunch of deprecated and immediate mode opengl samples in the wiki.

I think this is not quite helpful, as searching for up to date tutorials can be a mess, or rather, you don't even know you're using deprecated functionality until someone tells you.

Instead of rewriting all those articles which are still valuable it would be rather helpful to have a banner of some kind saying
[This is utilizing deprecated OpenGL functionality] or something and linking to an article explaining the problems around using it.

Could someone of you gfx competent persons create such a banner perhaps?

Tweaking one of the existing banner templates should be quite easy. Will have a crack this week.

Had a quick check, there's one there already.

Oh that's cool. Ill see if i can come up with an article explaining it, but i think my knowledge about OpenGL is not competent enough to do so without further research. If someone want's to help it's sure welcome

One thing you could do in the meantime is have a page that explains some of the major deprecations (such as the removal of retained-mode stuff... if that's what it's called -- y'know, the "glBegin()" etc. stuff), with a link to the different versions of the OpenGL spec (or a link to the OpenGL.org site's page that lists links to the spec of each version).

That way, we have something in place that can be expanded upon as time rolls along.

I really need to get to grips with the newer features of OpenGL. My GL tutorial framework stuff probably falls under the 'depreciated' banner. It was only when I started working with Android that I realised that I was doing it all wrong.

Yeah, it's a shame that they completely deprecated OpenGL's equivalent of "beginner mode". I would never suggest using it in production (performance is horrible compared to shader-based stuff along with VBO's and such), but it certainly makes OpenGL *much* more accessible to people unfamiliar with such an API.

That said, I think it will be a while still that devices still "unofficially" support deprecated OpenGL functionality. But, of course, I still would stay far away from it for any production release.

I totally agree to that, but given that you'll have to 'relearn' everything eventually (or maybe rather re-evaluate the understanding of graphics processing picked up so far) i would rather let people know as early as possible that what they do is not considered state of the art or anything close to that.

Especially since the vast majority of tutorials on OpenGL is using deprecated functionality new programmers can be easily desceived in thinking it is the norm using it. It is actually difficult to find decent up-to-date tutorials due to the amount of outdated ones.

Good point. Might as well get off on the right foot rather than start off using code that is 'bad'. The thing that is disappointing is that the "correct" way of doing things is MUCH more daunting to beginners.

Then again, there are people who STILL write code in VB 6.0... and STILL look for tutorials for writing games in VB 6.0...

Amazing for a Microsoft product that came out about 14 years ago, and has been officially abandoned by MS for probably more than five years.

That's what happened to me. NeHe lied to me man!



Sounds like a niche that GPWiki can fill.



Are we talking about Windows XP?

Sounds actually like a good plan.. we could sort the deprecated and uptodate tutorials in different categories so people will see immediately what upsides it has to not use the fixed function pipeline.

I'd be able to write a couple of basic tutorials i guess, but like i said i only scratched the surface myself a couple of month ago and still am a bit puzzled about the differences and inner workings.

I got around writing that article

http://content.gpwiki.org/index.php/Ope ... ctionality

i had it proofread by some ogl savvy dudes and it is apparently about accurate.

What i have in mind now is adding a series on modern opengl. I was initially planning doing this in C#, but since i have to become familiar with cpp again i will do them in in cpp instead.

I'm not sure when i will get around writing those though

Cool. I was thinking of doing a specific deprecated template for OpenGL, now it can point somewhere for more info.

Looking forward to seeing some modern OGL stuff on the Wiki. I did a bunch of reading on it the other day, but it left my head spinning.

it is actually quite easy, and once setup much less annoying to maintain.
stuff just works differently. i think thats the biggest hurdle
