The last time I was working on my "Alien Desert" image (which will
eventually use my improved sand...), I used a boxed pattern as
described. I had a bozo pattern for sand grains in the foreground, and
solid in the background.

The transition between the two was far enough away where you couldn't
even tell the difference between the two textures, so I don't know how
useful it would be for creating smooth transitions.

But it did make a big improvement in my render times. :-) Having bozo
all over a virtually limitless heightfield is slow. (I can't wait to see
how much slower SSS is!)

You know you've been raytracing too long when you downloaded and printed
the Renderman Interface documentation, so you'd have a little light
reading to take on holiday.
