Does anyone know of a macro or include file to simulate waves on the
surface of a fluid? I don't want to reinvent the wheel.
I'm thinking of something like:
loop
Buffer2(x, y) = (Buffer1(x-1,y)
Buffer1(x+1,y)
Buffer1(x,y+1)
Buffer1(x,y-1)) / 2 - Buffer2(x,y)
Buffer2(x,y) = Buffer2(x,y) * damping
end loop
Taken from

I wrote something to do the job in QB but I am no programmer and
cannot get it to work with an array larger than 121 x 121.
Thanks Stephen

This has been done before, Rune made several impressive animations with
that:
Subject: More ripples (408kbu)

Newsgroups: povray.binaries.animations

i think this was implemented as a POV-Script.
I also tested it myself (using a separate c program):
Subject: balls simulation (665k)

but neither of these has been published so i'm afraid you probably have to
reinvent the wheel for the moment (my program is not in a publishable
state).
Another link that might help:

Thanks Christoph,
I've now, sent him a begging letter. I have also seen your
animation and I am green with envy.

This is completely different, it is not using discrete points of a
heightfield but superposes sine waves with a certain distribution of
frequencies and directions.
