  Also http://prideout.net/ http://prideout.net/ has some very nice tutorials on advanced OpenGL topics (tesselation for example).

For everyone interested in learning OpenGL I'd recommend learning WebGL. It's the same graphics API, except that it runs in the browser so you don't need to mess with compilers and linkers and your scenes will work on all platforms. If you think it's fun you can then move to native OpenGL later (if you must – WebGL is good enough for surprisingly many things).
- novaleaf 11y ago
  is this tutorial applicable to WebGL? if not, do you have another tutorial recommendation?
- chejazi 11y ago
  WebGL has pretty good browser support - most recently Safari on iOS 8. http://caniuse.com/#feat=webgl http://caniuse.com/#feat=webgl

    Still doesn't work on my laptop in Firefox, and only works on Windows in Chrome.

      Maybe your graphics driver is blacklisted? https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drivers https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drive...

    Pretty good is not good enough for production type stuff yet. Did some testing with an older Mac Mini (Core2Duo) running OS X 10.6.8 and some of my simple WebGL tests would hard crash the operating system. WebGL is still far away from widespread distribution, I hope it will get there in couple of years.
- glhaynes 11y ago
  Strongly agreed, and I'd add another benefit that I've found to be even more important: nearly everything that comes back when you search for "WebGL" will be relevant. That's entirely different from the situation when you look for OpenGL information: old OpenGL is very different from newer OpenGL which is pretty similar—though not entirely—to OpenGL ES 2.x (which is quite different from OpenGL ES 1.x), etc.

  Good old Nehe O7
- moron4hire 11y ago
  The thing about NeHe that people seem to forget is that it was always complete garbage. It was just the "only" OpenGL tutorial that included readily copy-pasta'able code. Didn't matter that code was a smorgasboard of bad habits.

    Smorgasbord :)

    I think that applies to C code in general unfortunately, it took me a while to realize that C could actually be a very nice language to write in, but only after reading some of the source of Plan9, OpenBSD, redis, etc. Code you find in C tutorials is usually horrible.
franciscop 11y ago
Yes! This looks nice. I tried learning OpenGL some time ago but the resources were so mixed up and low quality that I gave up after few attempts. I might try now again because I remember it was really fun to make my own code generated 3d cube world (:

It would have been nice if it was not just for visual studio. (I like the features of visual studio but i am never going back to windows.)
- zamalek 11y ago
  http://opengl-tutorial.org/ http://opengl-tutorial.org/ is pretty fantastic cross-platform modern OpenGL (GL3+) set of tutorials.
- maccard 11y ago
  I had a quick look, and the only visual studio specific part I could see was building GLEW/GLFW from source, which is done using cmake. you just replace the setup of the headers/libs/paths with whatever platform you're using.

I've read many parts of this tutorial, it's very good and explain thoroughly how opengl works. It's both simple, short, doesn't go into too much detail, but provide the essentials you need to know. The most attractive aspect of this website is that it's oriented towards opengl 3.3 core profile, so it's really up to date, but now I admit I don't understand how vulkan will change that.
- jhasse 11y ago
  If I'm not mistaken, one can still use GLSL with Vulkan. So at least that part won't change much :)
  - jokoon 11y ago
    Isn't the purpose of vulkan to have an API that can do both what opengl and opencl do ?
    - jhasse 11y ago
      Yes, also better multithreading support and lower overhead (like AMD's Mantle which Vulkan is derived from).
