Hi all,
i've been mucking about with one of the tutorials which describes how to make terrains using only functions and i'm enjoying the one about the sand dunes.
I was wondering if anyone knew a way to make sand dunes (not the ripples in the sand) like you can see in the following pictures...

I have been trying to make some using the perlin ridges or perlin billows power fractals but am not having much luck. I especially like the first and second pics and the way the dunes look in them.
If anyone has any ideas, i'd love to hear them.
Cheers
