Actually I have no idea how this stuff works. It just does. I might have a
slight clue about the basic algorithm as it is explained on Hugo Elias'
page, but why it forms nearly circular ripples, why it reflects so nicely
off the walls and all that I don't know. Seems like magic to me... ;)

I'm not sure what sinus water by Christoph Hormann you're referring to.
Maybe you mean the sinus waves by Chris Howie? Anyway, mixing several
completely different techniques together is not as easy as it might sound.

Who knows? Any test animations you'd like to see?

Thanks for the tip. I'm not sure the techniques will mix well, but I can
give it a try.

:) Thanks!
And the same to you I might add!

Ah.
I don't know much about how objects on top of waves are moved around, but
besides that it should be no problem.
The walls can be defined with any function, so you can use image_maps,
object patterns and all other kind of things.

Err, they would stay longer!

I've looked at the code Hugo Elias explains and think
I got the idea on how it all works. How exactly does
your version of the algorithm know, where to
act as if there is a wall? Using trace to "simulate" a side
of the mesh, or what?
I'm not sure anyone else but you would understand the
question, but I'd still like to know... ;-)

You can't do anything wrong by trying :) But I'm afraid it won't give very good
results. The granite-pattern won't interact with the environment...

Huh? No, no trace involved.
I wonder if you're making any tests of your own with the algorithm, or if
you're just having thoughts, because when I made my first simple tests, I
found out how to make walls pretty much by accident and it's not unlikely
that you would too...
So I'll encourage you to start experimenting! :)

Sorry, I just saw it now.
I'll have a closer look.
