I decided to have a play with ridged_mf. Usually I avoid it because it has
all those parameters and granite generally looks good enough. Anyway, I came
up with something rather good!
Render time 6h 36m.
I'm very pleased with it, but the horizon looks wierd with all those wave
crests at exactly the same height. Also the water has a really nice media
for stuff underwater, which is slowing down the render time, and you can't
see any sign of it in this shot! doh!

Adding some turbulence or 3d noise could reduce that effect.

I love this look! I think an artistic, stylized, or idealized look can be a
lot more exciting than pure realism when making synthetic images, and I
feel you're onto something great with this one. Keep it up! I have a tool
that may help with that render time. Oh, and your signature rocks ;-)

That is one of the most convincing modeling of rough seas I've seen from
Povray so far! Kudos. The froth could look a little frothier though,
then it would be just amazing.

That's fantastic.
You might be able to fix the 'all at the same height' problem if you add a
large scale f_rand3d to the function.
How did you do the foam?

Maybe make the froth fade to transparent with something like a granite

I've now added f_spotted and the problem is completely fixed (plus it now
looks like an even more dramatic ocean!).
> How did you do the foam?
The foam is controlled using a nearly identical version of the f_ridged_mf
that defines the surface, but with the gain parameter cranked up a bit so it
picks up the higher frequencies more to make a more interesting shape.
That's averaged with a crackle form <1,0,0> pattern to look a bit like some
bubbles.

A while ago (for the Catastrophy IRTC) I have been experimenting with making
foam, but never got satisfying results... This looks much, much better!!

It looks really good but… and there is always a but :-(
When you get white horses like that the sea looks different see below for
reference.

George Pantazopoulos said “I think an artistic, stylized, or idealized look

and he is right. RL can be so disappointing.
I spent many hours wave watching when I worked offshore.

Words fail me, this is a masterpiece. Could you post a larger render,
or even the source?-)

Forget the granite texture, the current crackle form <1,0,0> should be just
fine with more transparency.

It really does look good. But I would rotate the ring about the vertical
axis a bit because the pattern is a bit too lined up with vertical,
especially with the reflections I am seeing an invisible vertical line...

Wow! Amazing! As said above, the stylized look can be much more interesting
than pure realism, but with you image you could go in either direction.
Very well done!
You know, if you keep posting cool images, providing help and source on your
website, and being quick to help with questions here, people may start to
suspect that your superbrain isn't so evil after all...

Really? But I'm encouraging people to develop skills that serve no
marketable purpose whatsoever! Just think of all those budding CG artists
whose lives I've ruined by leading them to povray instead of Maya!

That's a good pic. The water looks a bit hard edged though and the foam
doesn't quite look right. A good pic still. :)

Pretty good - the horizon looking strange might also be due to something
else. In real life you would have quite a lot of spray in the air in
such a situation that would limit the sight so you would not be able to
see that far.
There are various things that limit realism of course here (would need
more transparency and scattering on the wavetops and foam for example)
but that's not what you are after and it looks quite good as it is.

Yeah I was thinking of adding a little fog to take care of that but I
haven't got round to it yet :)

Firstly, the water is fantastic, really dramatic looking, I guess you could
adjust the size of the rubber ring to make the waves look even larger...
Secondly any chance you can post the improved render.

Well I was waiting until I let one finish with anti-aliasing turned on!
Trouble is I keep stopping it when it's half done to tweak the wave shapes.
Although I think I'm happy with them now, so I'm chucking a sinking ship in
there to show off the refraction and media effects below the surface. Here's
a taster (without anti-aliasing).

I assume you're using an isosurface? You could probably speed up the
rendertime (by several orders of magnitude, in fact) by first rendering
the pattern as a height field.

Were there some? I found it hard to see any in the picture.
Of course, you could use intersections between height fields, and other
such tricks, but that gets... tricky ;)

The overhanging parts aren't obvious in the first version of this image
(aside from the whole thing leaning left, but that could easily be done with
Skew_Trans on a height field), but if you look at my new post they're much
more visible.
The render time's mostly caused by radiosity (which I've since disabled) and
reflections & refractions. A heightfield would be a big help with those
because it traces very quickly, though the resolution I'd need for this
image would mean a huge pretrace time to generate that heightfield, and a
huge lump of memory to store it!

LOL! Yeah, I think about that often as I tap away at my keyboard hour after
hour, tweaking, adding new things, discovering new tricks, forgetting to
eat(!), etc. What can I say--I'm a slave to POV! Happily so!
Your images are simply fantastic, technically and artistically. They (and
the various suggestions of others) comprise one of the most interesting
newspost threads I've come across in awhile. MUCH food for thought here. I
agree with others: These are some of the most astonishing water waves I've
seen using POV-Ray. I *DO* like the "heightened realism"--like Old Master
paintings. Beautiful!
