OpenGL Extensions

What are OpenGL Extensions and who I use them? Where can I find information about it?


Extensions are (as the name says) extensions to the OpenGL core. Extensions is a way for driver developers to add even more functionality to their implementation of OpenGL. The core itself is a ‘basic set of functions’, but the newer hardware got capabilities far beyond this ‘basic set’, and then the manufacturer add more functionality through extension, since it’s not a part of the core.

Some documentation can be found in the Documentation-section here at .

If you want information about the extensions, go to the Extension registry .
