I guess that the reality would be gone then. Because you'ld
have to move the different scales of the MF at different speeds
(is this possible?)

Or upward and to the side at the same time might simulate wind affecting the
waves.

I don't think so...the different frequencies/scales should take care of
it. It isn't an actual simulation of water anyway, so it doesn't really
matter...as long as it looks good. :-)

I'm not sure how it will look like.
Anyone willing to do a small anim?

Moonlit water is what it looks like, has the color of a lake near here at
twilight.

Oh come on now. Seriously, this coudn't possibly be a photograph. If it is,
then why do I try so hard to imitate real life for if it actually looks like
this? :-)

Hi Alberto,
great job. IMHO the water surface needs some more fine structure.
Try a superposition of 3 ridgedmfs, where the next is about
1/3 or 1/4 scale of the previous each. Something like
isosurface{function{y - myridgedmf( x, 0, z)} +
0.3 * isosurface{function{y - myridgedmf(3*x, 0, 3*z)} +
0.09 * isosurface{function{y - myridgedmf(9*x, 0, 9*z)}
You may want to try different scaling factors.
I think this would provide for a nice animation as well,
shifting the 3 components with different speed (first one
fastest).

Is this really a photograph? I've never seen water this blue, even when
someone adds blue jello to it.

I agree. I'll post a brighter image.

Thank your for your comments. I will give a tray to your suggestions.
About the animation I'm not sure. mac povray outputs animation in quick
time movies and I'm not sure if that is a good format for posting in the
corresponding news group.
Alberto.
