Register Combiners and Fog

[Korval]

I'm wondering: how do you set up register combiners so that it performs the usual fog computations that would happen without combiners?

Use the final combiner's AB+(1-A)C computation, which looks suspiciously like a fog blend. The fog register's alpha becomes the fog factor in the final combiner.

Well, I suppose I could do that if I wanted the right answer. http://www.opengl.org/discussion_boards/ubb/smile.gif

Now I feel like an idiot.
