- groundfog.jpg demonstrates the variable fog denstity
- feature I added to POV.

- groundfog.tar.Z contains the patch and an example scene.
- The patch can be applied to version 2.1 and 2.2 sources.
-
- The patch adds a new keyword ydistance to fog statement.
- The fog density varies along y axis like this:
-
- -y
- ---------
- ydistance
- density = e

- I have been told that the patch does not work on PC:s
- (overflow/underflow errors). It has worked fine on HP705
- with HP-UX 9.01.
