   Beginning OpenGL
  I'm trying to learn OpenGL. Unfortunately, I have no clue where to start. I am a poor college student, so I can't buy any books. I haven't been to my library yet, although I plan on going when I can get some transportation.I mainly want to try to use OpenGL to render 2D objects onto the screen. I'm trying to make a 2D game but I want to use OpenGL to draw said 2D objects. I don't want to get into heavy 3D stuff yet - I'm just trying to learn the syntax for OpenGL first. And maybe some effects or something.   
  If you only want to do 2D stuff, take a look at SDL. There are a lot of good and free tutorials available on the web.But if you want to use OpenGL directly maybe this would be a good place to start.And BTW you must be REALLY poor if you can't even afford a book. :P   ;  College student. Debt. Etc.Also, I've been to NeHe. I should've stated that. I want something that'll explain the in and outs from the bottom up of what every function does, how to use them, and a practical example.   ;  The GL spec is available for free from opengl.org. A more readable (but less up-to-date) guide is the OpenGL Programming Guide. The  man pages are OK, but only covers GL 2.1.AFAIK the ARB just doesn't have the funding to produce documentation which is complete, up to date, and readable at an introductory level.   ;  Bookmark this page:OpenGL 2.1 Reference PageAnd have it open while you work through the Nehe tutorials as it'll explain what each function does as you come across it.  You can also hunt around on opengl.org for a lot of other information.*edit: doh, mrbastard beat me to it.*
