I recently downloaded Wilbur
(http://www.ridgecrest.ca.us/~jslayton/software.html), after I saw the URL
in Hans' post about his 'Snowy and bizzare' picture. I just want to say, if
you don't have it, it is worth checking out. I have figured out quite a
bit, and what I have seen is very impressive. If anyone has much experience
with this (free) program, then could you please educate me as to what the
variables in the generate height-field box are. The help file just makes
obscure remarks, and refers to some book. Even though I don't know what
they do, by inputting random values, I have managed to produce some pretty
impressive hf's, but it would be helpful to know how to get exactly the
effect I want.
Any help would be much appreciated.

I've just recently begun playing with this sort of HFs. My
impression from all I read about it (and from my own humble trials) is
that getting control of this is an art of its own. There are people
who are investigating these things as their main job. And even the
greats are saying it takes a lot of experience to get a feeling of
which parameter does what.
My recommendation: Have a look into literature, be aware to spend
much, much time on it, and play, play, play ...
Wilbur is a good means here as it produces even floatingpoint-expensive
HFs in a reasonable time.

Don't vary them too randomly. Start with small variations of the
default
values. That way you'll get a feeling for their influence.

I'd like to know that, too :)
