water simulation in the form of force blocks alike stuff? or real water sim? the later will never happen, that trivial it is (cause that requires an nvidia dx10 card and windows, without nvidia hardware you can not even do a simple slime blob on a core i7 before droppigng to 20fps on an otherwise empty scene)
But at least Unity 3 has answered a widely spread want/need (depending on your wants and needs)…
Cloth Sims!!!
Now I won’t have to play around with bits and pieces of code to just make a little bitty piece of cloth collide with something other than a defined variable!
I was astonished to see a video of a realtime ocean geometry shader which looked absolutely fantastic with highly detailed realistic waves in realtime. It’s already possible, just a matter of hardware support and Unity’s interest in implementing it.
In general though it has to be somewhat faked because even a 2D fluid simulation is very computationally intensive, yet alone a 3D volume of any size.
You migh want to check the wiki, maybe this already what you need. There is also a thread on the forum and as far as I remember someone also tried to implement simulation of objects on watersurface not sure if it comes with nikko’s project though.
Thanks for clearing that up, I read about Physx only working on Nvidia cards at one time and issue between Nvidia and ATI with the whole system and I got confused as to how Unity and Physx played together. Glad to know that Physx performs equally well on Nvidia and ATI cards.
