Where do I get the OpenglSDK?

The subject say it all…
Maybe I’m a little confused , but I can’t find it anywhere. I think there are more than one distribution. There is only a Cg sdk on the nvidia pages…

There is no “official” OpenGL-SDK like it’s the case with the DX-SDK from MS.But you can get OpenGL-SDKs from the big companies like ATI and NVidia.

What you need to start developing OpenGL apps should be included with your compiler. But with VC6 you only have the 1.1 version directly available. From ISVs you get more specific stuff (extensions), demos, presentations, and Nvidia has a nice SDK, it’s about 70MB (the last I downloaded).
