It's pretty much all about the specs for me. Admittedly I'm not very into OpenGL coding at the moment (I'm using Unity for most things). I used to read the extension files, but are there that many cards that support extension features (presumably for 4.0, so things like tessellation / transform feedback?) that don't just support the creation of a better context in the first place?

Here's a link to an OpenGL cult group http://blog.wolfire.com/2010/01/Why-you-should-use-OpenGL-and-not-DirectX CodeSamper has some good OpenGL tutorials: http://www.codesampler.com/oglsrc.htm So does Lighthouse 3D: http://www.lighthouse3d.com/opengl/tutorials.shtml

I just think a lot of people default to D3D now a days because they want a job making games. Currently the vast majority of AAA companies produce for windows/consoles. I have noticed in recent times however, that more and more companies are starting to look at Mac as a viable platform mostly due to them experimenting with iPhone and realizing it is just as easy to code for the Mac. So now not only blizzard are targeting mac but valve and bioware as well. I am sure more will follow and with that we will see a pickup in the OGL community that has kind of become a niche community of insiders only.

I've been struggling with this lately. Up to date documentation and examples/tutorials are lacking. The NeHe tutorials haven't been updated in years. OpenGL is currently at version 4.1 but most pages I find when trying to learn about using it are based around version 2. The latest version of SDL ([url="http://www.galaxygameworks.com/products.html"]1.3[/url]) says it supports OpenGL 3.0 - I don't get why they wouldn't update it to support up to the latest version.

I want to learn to use OpenGL due to huge amount of platforms that it is available (and I like to use Linux). Mobile devices, tons of operating systems, and even modern browsers. The potential for it is huge but it's really hard for someone like me that is starting out, finding good resources to learn from.

@RSU - AFAIK the light house and codesampler pages on opengl are really outdated haven't checked them in a while.

Have no idea what happened to the OpenGL community. In the mean time I have done a little search and found these:

[url="http://www.opengl.org/wiki/Main_Page"]OpenGL.org Wiki[/url]
[url="http://duriansoftware.com/joe/An-intro-to-modern-OpenGL.-Table-of-Contents.html"]Durian Software - An intro to modern OpenGL [/url]- Found in OpenGL.org news
[url="http://www.spieleprogrammierung.net"]Spieleprogrammierung[/url] - Found in OpenGL.org news (it's German but looks packed with content)
[color="#0000EE"][url="http://sites.google.com/site/opengltutorialsbyaks/introduction-to-opengl-3-2---tutorial-01"]OpenGL Tutorials by Aks - Introduction to OpenGL 3.2[/url][/color] - Found with Google
[url="http://db-in.com/blog/category/opengl/"]db - interactive blog - OpenGL [/url]- Found with Google I think

Note that I haven't read through any of these so don't know what they're like.

So I guess OpenGL.org would be the definitive OpenGL community now days.

When I was subscribed to the OpenGL.org news every so often there was mention of tutorials, definitely worth having a look through that. You get plenty of results if you [url="http://www.google.com.au/#q=site:http%3A%2F%2Fwww.opengl.org%2Fnews%2F+tutorial"]Google their news[/url].
