I try to avoid asking school specific problems on Stackoverflow, but I've ran into a bit of a problem, and was hoping someone here might be able to point me in the right direction.
I'm currently doing a Graphic Programming class in college independently (no class, just me, a book, and the teacher). However, the professor doing this is very specific. I have to work with OpenGL, in Linux, using only C. The professor lent me a book, but it's an old one, and to my knowledge, a lot of the stuff presented in it has changed in more recent years.
Given these restrictions, can anyone suggest any books or online resources that can help me get going given these parameters? The professor is quite adamant on this, and most of the stuff I've found to date involves either Windows development or more recent languages like Python.
