I just want to start graphics programming, and it turns out that OpenGL is appropriate for me. But the problem is, i am having difficulties in differenciating GLUT, GLEW, OpenGL, GLSL, blah blah blah, and is there any tutorial that will guide me in learning the real GL language?
I'd suggest a book! Although... I'm reading a couple right now and they certainly don't clear up some common newbie mistakes.
OpenGL isn't a language. GLSL is a language that is compiled via OpenGL. GLSL is a language meant to process specialized types of data specific to 3D rendering. It's also optimized for a GPU rather than a CPU.
If you start using OpenGL, use something that helps you see what's actually going on. I would highly suggest apitrace: http://apitrace.github.io/
Just remember that OpenGL is little more than a library that holds state concerning the GPU.
