I have just started reading NeHe's tutorial (OpenGL 1.x) and have now been told that it is old and that I should learn a newer version. I am ok with it being harder. What version should I learn? I am guessing it would be the newest (4.4 - I think). My computer does support OpenGL 4 (OS: OS X 10.9 Mavericks). Even though I am programming using Objective-C with the Cocoa API, I know C++ and WinAPI, so I can easily translated it. Next, What is a good tutorial for the version of OpenGL that you said for the first question?.
Thank you very much,
