OpenGL is just an API, really. So you really want to ask, "Are particular implementations of OpenGL free?"

The answer is, yes, there are free implementations of OpenGL. Mesa3D is a free-as-in-speech implementation of something that very closely resembles OpenGL. It is available at www.mesa3d.org. (http://www.mesa3d.org.)

Microsoft also gives out a free-as-in-beer implementation of OpenGL... I lost the link. It's somewhere on www.microsoft.com. (http://www.microsoft.com.) It should be installed if you have Visual C++ 6 (I think).

NVidia also has a free-as-in-beer implementation of OpenGL... it's available from www.nvidia.com. (http://www.nvidia.com.)

SGI has implementations for Irix. I think they come with Irix, but Irix is not free (or is it?).

Hope this helps.

So, everything is free, if I just wanna learn it? I'm just a beginner and don't know what you mean with free-as-in-(name).

Yes, you can program in OpenGL without spending a cent. However, spending some money on a good programming environment like Microsoft Visual C++ might be a good idea if you are serious about programming OpenGL.

what does "free-as-in-beer" mean?
By the way, are there any downsides to using glut with visual c++ 6 for fairly simple applications?

In English, "free" can mean either "liberated" or "without cost",
"libre" and "gratis" in Latin.

free-as-in-beer is used to mean "without cost". free-as-in-speech is used to mean "liberated".

None that I can think of. In fact, GLUT is a great way to get going quickly, and make your stuff portable.
