All official extensions are registered at the OpenGL Extensions Registry, maintained by SGI at : http://oss.sgi.com/projects/ogl-sample/registry

>> Does ati also have ogl extensions?

Yes, you will find them in the above link too.
Though, ATi now mostly relies on ARB extensions while nVidia still is very active on vendor-specific extensions. There are lots of pros and cons with either of the point of views, but please don’t argue about them because it’s rather considered a flame war.

AFAIK DirectX doesn’t have an extension mechanism.
