I was wondering how much C++ experience you needed to learn OpenGL? And also what kind of things can you do with OpenGL using Visual C++ as a compiler? THx in advance!

You can use OpenGL from most programming languages. That''s not a problem.

As to what you can do with it! Well, that''s a verybig question in it''s own right. It''s used for Profressional flight training simulators, medical research visualisation, realtime data rendering etc. Or do you mean in the gaming sense? If that''s the case - Look at any game that id Software (amongst others) has produced. Ever heard of Quake 3 Arena? That''s OpenGL through and through.

BTW - You''re in for a big learning curve, but I promise you''ll have a lot of fun along the way

yes...i know the whole Quake 3 engine is based around OpenGL. But they didn''t make that whole game using text based compilers did they? That would be a big job wouldn''t it? Wouldn''t they have something with a GUI to make that?

oh ya.....i don''t need to know any previous programming languages before learning OpenGL?

Maybe I''m wrong here, but I get the impression that you think OpenGL is a programming language?

OpenGL is simply a graphics API which at it''s simplest draws basic geometry (primitives) onto the screen. This API is accessible from many languages.

Almost all professional games are made with either C or C++.

Generally they will also use either OpenGL or D3D. Both of which are graphics APIs.

"but you could make a full fledged 3D game with C++?"

Yes, I do not know if you meen with ISO c++ only and not useing any API eg. DX or OpenGL, or if you meen with C++ useing OpenGL You can do it both ways but but trying to make a game with out any graphic API is a very hard task. I hope that I understud you qustion.

I know very little C++ but I''m not finding that too much of a problem doing opengl with it so you should be fine

I disagree on that. I feel that OpenGL would be very difficult if
you don''t have a good understanding of programming(in General).
Program for a few months in C++ or BASIC to get the idea of programming.
After which I would recommend learning some windows programming (MFC or Win32 API) and vector math, matrice math and geometry.
I''ve been programming fro 7 years now(working as a Web Devloper right now) and just recently got introduced to OpenGL. I am finding it very challenging but am sorta getting the hang of it.

sure, I definately wouldn''t recommend learning opengl without a good knowledge of programming in general

hrm...well i''ve taken a course in VB...and done a bit of C++....but could anyone point me to a good site to learn some more C++?

DirectX and OpenGL are not programming launguages, A game is just a bunch of function and variables interacting with each other. The whole game is running in the background and what you see on the screen is just a visual representation of what the variables represent. And in order to draw these graphics to the screen you use either OpenGL or D3D (assumeing you want high quality graphics).
