Here's that dynamic grass thing I was talking about:
Movement - WASD / Arrow Keys to move the Black Ball
mouseX controls the radius of the disturbance point ( Black ball), and mouseY controls the strength. For "realistic" results keep your mouse near the very top of the movie.
Also what's funny is that it was lagging on my computer, but no lag when I run it on the dumping grounds....hum...
All that grass moves like that just by me changing 4 or 8 parameters (I have a total of 8 points controlling the field). I also have ideas on making the grass like this tiled, which would be way more efficient in an actual game.
Your dynamic grass looks pretty good. First I thought the ball was moving in a hamster ball because there was something like a globe around him :P, but then that changed to just a small circle and I could see he pushing off the grass while moving. Also the wind over the grass looks really cool.
Also yeah, Joey Betz's tests on the viscoelastic fluids algorithms was pretty cool, I remember I already saw that hundreds of times on his website.
I also like a lot Fluids Simulation fluids simulation:
You can move the fluid with the mouse.
It is awesome! Looks very realistic!
