OpenGL versions & extensions

OpenGL OpenGL: Advanced Coding

Hi all,

Were can I find a list of OpenGL extensions supported by each OpenGL version? :rolleyes:

I mean, what are the ‘standard’ extensions for OpenGL 1.2, 1.3, 1.4, etc. :confused:

thanx!

I think you don’t understand how OpenGL works. Once a extension has been rolled into the core you can use the new “core” version with only checking the version number.

(on Windows you do have to load these new core functions via wglGetProcAddress however - or use glew)

A list of what extensions got rolled into the core is available at the end of the OpenGL spec:

Thanks, I’m just planning to organize my extension loader by OpenGL version.

Why you don’t use GLEW or a other extension loader?

Yeah, one line of code to initialize glew.

And another line of code to ask, whether an extension is available.

I want to see how it could get easier.

I just hopped on board with GLEW and have been very pleased. With one exception it has been a very easy library to use. The exception is that the release I am using causes a core dump when I call glBlendEquation. I think there is a function pointer conflict. Other than that, it has been “fool proof”.
