Significantly less impressive than you'd think. Check out page #3, for
example. It appears to be merely a trivial repeating texture. There's no
hint of all the complexity that the paper claims goes into generating
this...

It *is* a trivial repeating texture, when static. See page 9.

Probably because it's not animated, and thus a dynamic flow of water isn't
going to be obvious in a printed paper.
Thanks for the paper, tho. That's interesting.

Yeah, that was my conclusion too.

I'm still waiting to see a water system where the ripples reflect off
obsticles in the water. I mean, hell, it can't be *that* hard to fake
such an effect, even if solving the wave equation for real is too
expensive...
Then again, I'd also like to see water that *isn't* a mathematically
flat plane. :-P

Tim Nikias did a water simulation some time back. It is a 3D SDL one.
It can be found at http://www.nolights.de/downloads.html#lssm

Wrong group! Wrong group! You must stay off topic! ;-)

I think there was a boat racing game recently that did this (the boats
affected and got effected by the waves). Simulating the wave equation
(or a good approximation of it) is quite easy to do now on the GPU
thanks to being able to use texture lookups in a vertex shader. Having
it interact with other objects seems a simple case of having an
additional 2D texture to show where objects are, and then using that as
you're solving the wave equation.
