Where can i download OpenGL API Reference?

Is there a website that has all OpenGL API functions Listed and explain the parameters, returns for all functions?

Have a look at the OpenGL specifications . A document describing all functionality in depth.

Or look at the Blue book.

Thanks, that’s enough for me to work on now.

On-line SDK at M$ site : OpenGL Programmer’s Reference

There’s a nice reference to OpenGL at
