Hello, I have been searching for good modern opengl + C tutorials with google. Everything seems to involve C++ somehow. I do not want to learn a new programming language to do something that should be possible with C. I've tried to read many opengl + C++ tutorials and adapt them to C, but the problem comes when I need to do transformations. Then many tutorials link to GLM and force to switch to C++.
I know i could just make the file from .c to .cpp but I think it's kind of stupid to write programs in C and then get some useless overhead from C++.
So I'm asking if you know a good C + opengl tutorial? (also I'd prefer them with SDL, but it's not necessary since adapting that is easy.)
