I've been toying with an idea for an upcoming game of mine that (as a small part of play) models water flow and pressure as it moves through chambers. It's a side-scroller, so the water has depth, and pressure is modeled based on depth.
At the moment, it actually looks quite beautiful... even splashing, sloshing, and seeking its own level, no matter how complex the chamber shapes. I have one more detail to work out regarding apparent volume decrease due to pressure, but I'm getting there.
I was just wondering who else might have worked on something similar, and have a little input on something technical (regarding the above problem). I'd be willing to give you a glimpse at the project, if you think you might have some useful information to help perfect this. Lexy, I remember you had water in Miner League, but I don't know how detailed your modeling was.
