Entering OpenGL with/without Qt, benefits and costs



I’m new here and and hope to gain the answer of my questions. I also searched the web but couldn’t reach what that covers the questions completely.

My questions:

A) Does Qt cover OpenGl well? If so, what tut/manual do you suggest for starting?
B) Is OpenGl the same? So why can we learn it by Qt or other tools etc.?
C) For a C++/Qt programmer what is the best way to learn openGL? Any manuals/tuts?

I also found four tuts that I can’t send them here! :frowning:
I don’t know how complete they are or even which one is useful for me to start.
Please state your opinion guiding me choose my route.
