I prefer the small ring animation, mainly because of the transparency of the
water which gives a nice refraction effect on the bottom of the pool. The
more irregular motion of the torus also seems to create more natural
patterns on the water.

I prefer the large ring animation. The water effect seems less confuse, and
prooves that any object can interact with the surface. I really like the
animations on your webpage too. They show, how the system works with other
enviroments than a box.

Best regards,

I prefer the big torus rotating around itself, but it would be nicer with a 
less dirty water.
  As for ideas, I don't know much:
- objects falling in a pool and drowning
- a boatplane  taking off or landing on the sea

Thanks for the comment. Regarding the comments
so far, I'll perhaps try and create a more complex
example which takes some of the suggestions into
account (in your case the clear water for the refaction
effect and the irregular motion for natural patterns).

Thanks for the comment and the suggestion
about a different environment. I'll incorporate that
into a more complex example (once I've got the
time).

The idea with the boatplane is nice! Perhaps
that'll make a nice example:
Boatplane landing on the surface, turning around,
and taking off again... Thanks for the comment!

The talk of seaplanes reminds me of the post "water skiing" in
povray.binaries.images. For images such as this one, it might be useful to
calculate what the water would look like if the plane was moving across the
surface, but only render one image. Can your system calculate multiple
frames of water calculations in one pov-ray frame to allow this sort of
still image creation? If it isn't too much hassle to implement it might be
quite useful.

Another thing that occurred to me from the suggestion of objects falling
into a pool: how easy would it be to make a 'floating' macro where objects
float on the water and bob about in the waves? The trace function would
probably come in handy here, but I can see potential problems with waves
bouncing off these objects rather then moving them. Any thoughts?

As for the still image:
Possible indeed. Set the animation-timeframe of the
plane before 0 (like -1 to 0), and set the simulation-timeframe
appropriately (like from -1 to .1, to make sure the last frame
is caught). You've got to wait a little then, but that works
fine.

As for the object-floating:
I've given some thought to this as well. Best would probably
be a two-pass method: render the animation and use trace
to determine where the object should be sitting. Then do
another pass with the object animated based on first pass.
Another try might be to have the object "lag" by one frame.
When using a high enough resolution for the water, it won't
even be that visible. You'd then have to keep track of the
new position, put that in proper file for the system to backtrace
the animation of the object (which is needed for the waves to
be generated).
Problem with this is that the water actually checks for insidedness
of the calm nodes, not the displaced ones. Perhaps I'll change that.

Anyways, if anyone can come up with a method without intervening
with the standing structure, he/she is invited to give it a shot. Haven't
got the time right now, but I want to cover that issue at some point
as well.
