I agree,  This is the best example of this algorythim I have seen yet!  So
are you making an include, or are you at least going to upload the scenes?
Rune and Christoph posted similar animations, but never gave the source :(

Ewww, paradoxical refraction!

Great animation BTW.

Woooow, I really do.
I fear I'll never get to that level.
Very beautiful.
Keep it up!!!

I plan on releasing it ASAP, but there are some issues
about how object have to interact with the surface. That
needs some trial-time, and since several planned additions
are likely to change some major parts of the code
(like precalculating walls, instead of just using the surface-
perimeter for reflection of waves; only processing the
nodes which actually contribut to changes of the surface),
I didn't release anything yet.

But as soon as the fundamental part (the setup of the surface,
its handling with boundaries, and speed-ups of parsing) is
implemented, I plan on releasing that along with the
rain-drop algorithm (which just drops some "wave-emitters"
every frame) and the boundary-algorithm, so that it is at least
possible to set a surface and let rain drip on it. The latest
macro, which drops a wave-emitter at a specified point, would
come along, and then there's something for you to toy with. :-)

How come you think its paradox? The ior is
1.33 => water, thats all. It might look a little
strange with only the top-surface showing though...

Thanks for the praise, but what makes you think you'll
never get to that level. You're pretty good as well, you
could give it a try. You also have to keep in mind that
the totally useless codes and attempts before aren't
to be seen on these groups... ;-)

You'll find the first test of interactive-objects here:

http://www.digitaltwilight.de/no_lights/mpeg/water5.mpg
 (This one is 745kb, MPG1)

It's not really the sphere interacting with surface though, but
rather the initial attempt to map a certain position onto the
surface and cause a wave-emitter there. The sphere doesn't
block waves or actually cause them by its size, its just a
single node being influenced here. This will be addressed
later.

This one isn't looping. The algorithm doesn't allow later
adjustments, at least not yet. I'm hoping I can change
that.

Enjoy,
Tim

That's what I meant. There's only one refractive surface although the image 
seen through the water doesn't seem to "un-refract."

The links are now outdated. My homepage got updated and
you'll find the animations in the WIP-Section.

Regards,
Tim
