Finding Opengl in site

By curiosity I have to seek a means of downloading OpenGL on ATI,
nothing to find!
Does OpenGl settle you at the same time it as to install the drivers videocard?

You get OpenGL with the catalyst drivers, but if you want to write OpenGL software you’ll need the header files and libs these should come with your compiler dev environment but to get extension prototypes etc it’s best to use an SDK from ATI, so download the SDK in addition to the driver from, then you can be sure you have everything you need to write code to use the latest features on your choice of card.
