For the foam I gave up the object pattern trick because it is boolean and
not good at close-up
I tweaked a function based on the same image as the isosurface terrain.
This function fills the crackle pattern at hi values and let it empty at low
values.
As usual comments are welcome :-)

Big improvement, a lot more realistic. Your water is great. Time to
concentrate on the ground.

That's the best sea I've seen anywhere - well done.

Hi Marc, that's excellent! Great sea. I would have a go at adding
just a little hint of 'off-yellow', or 'cream' colour, if you will, to
*some* of your surf.

I also like the translucency of the waves just behind the surf. Spot
on! :)

Thanks
Good idea for the cream color at thickened zones of the foam (I think it
happens only when seawater is carrying plankton, though)

curiousity, how tall is a lighthouse typically ?
how tal are the walls around the field ?
do the two and the view angle look correct ?

Are you cheating? Is the sea a photo?
Not the foam - that is obviously CG - but the sea looks suspiciously like a
photo of some sort.

Your image has some shocking realism present in it. The grass, though,
could use some improvement(IMO).
Is that ocean an isosurface? A height_field of that size might take up a
huge amount of memory...
Good work~

Impressive foam, Marc! Much better indeed than previous one. However, the
crackle pattern seems a little bit too angular to me...?

LOL no thanks, the only bitmap in this scene is the one to generate the
terrain in an isosurface and the foam distribution.
The sea is an isosurface as well with combined unevenly scaled bozos (for
the swell) and f_ridged_mf function (for the ridges)
I'll post the code on p.b.s-f as soon as cleaned

You're right grass is scheduled as "to do"

Thanks Tomas
Yes I think it needs to be scaled down a little and warp turbulence scaled
up so angles should vanish

This one is about 37m tall and the walls are about 0.5 to 1m.
