OpenGL is a *specification* and as such has no source code. You can find the specifications here: http://www.opengl.org/documentation/specs/

OpenGL drivers are typically written by the manufacturer of your video card and tend to be closed source. Mesa3D (http://mesa3d.org) is an open source implementation that runs on many operating systems.

"Open" in OpenGL means "open standard", not "open source". No need to curse.

So, how can I create my own ogpenGL library?

What exactly do you want to do? Create a 3D-application using the OpenGL API or create an OpenGL implementation such as a software renderer? If you want to develop a 3D-application, i recommend reading the "redbook" http://www.amazon.com/OpenGL-Programming...34781759&sr=8-1 (http://www.amazon.com/OpenGL-Programming-Guide-Official-Learning/dp/0321481003/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1234781759&sr=8-1) or the tutorials at http://nehe.gamedev.net/ although the book is so much better :)

create own software renderer is tough if you're an expert in 3d graphics, impossible if you're not. consult mesa3d for more information on software rendering. it provides its own dll where software rendering is done, original hw OpenGL dlls redirect it to the driver.

You should download MESA
