Not really fogging or mipmapping, but more of a simple gaussian blur at a distance. Plain mipmapping would probably work just as well, but I think blurring would look better. Now that I think about it, if the mipmaps could be custom defined, then blurring wouldn't be needed. Also, is there a way to make a pixel daker as the camera gets further away? That would help me alot, too.

Thanks,
