I just need someone to confirm/deny this for OpenGL: fog (like in the fixed funciton pipeline) is still applied after pixel shaders in OpenGL.

The DirectX pipeline I know works this way and I need to make sure before I write any code for my project.

Hmm.... That's aggravating... Completely different in DirectX...

Well, I guess this is good actually since even in DirectX, fog is supposed to be done in pixel shaders for version 3.0 and above...
