http://physbam.stanford.edu/~fedkiw/ - Jacob3d, on 01/30/2008, -0/+23Mad kudos to these guys, I still have nightmares from school with trying to simulate fluids in LightWave or Maya. Even after days or weeks of tweaking and sending it off to the render farm it almost never came out right just due to the extreme complexity of fluid dynamics.

- Brian48216, on 01/30/2008, -0/+10I wish they would actually include some of these winners into the actual academy awards instead of having a completely separate awards ceremony.
It's like they wanna keep the nerds away from the beautiful people or something. - beclamide, on 01/30/2008, -0/+9Same here! I ended up leaving out all the fluid dynamics I needed for my final project because, not only did XSI constantly crash, it took a month to render off 4000 frames as it was!
Wish we had this 8 years ago!! - beclamide, on 01/30/2008, -0/+8Video here in case no-one posted it in the time it took me to write this sentence:

- capiCrimm, on 01/30/2008, -0/+4just turn in an empty project and tell your teacher you simulated evaporation. Easy Pass.
- chris9902, on 01/30/2008, -0/+4cheers. Why they couldn't provide links I don't know. Maybe I expect too much.
- takeo1775, on 01/30/2008, -0/+3possibly worse than being rick rolled
- beclamide, on 01/30/2008, -0/+3lol damn! Dchandaman wins

the recent Wired Science podcast "Perfect Water"
10 minutes long - gmiley, on 01/30/2008, -0/+2All of those animations are pretty damn impressive actually, but I think the "chemical reaction" one showed a good mix of materials of varying consistencies all interacting together.
- antler, on 01/30/2008, -0/+2He finished his PhD in 1996 and consulted for Industrial Light and Magic, so chances are, he was involved in much of what you have seen over the last decade.
- capiCrimm, on 01/30/2008, -0/+2***** the fluid simulation. Tell me more about the MANTASUIT.
- LLLSecretChimp, on 01/30/2008, -0/+2Why should the Academy be any different from the world?
- iiBeLiEvE, on 01/30/2008, -1/+2Hey, look, it's Crysis on all low settings.
- Stevethegreat, on 01/31/2008, -0/+1Wow, consider me impressed! When are going to see those effects on videogames?
- sgtbutterscotch, on 01/30/2008, -0/+1At the bottom of his website are links to pictures showing him with ridiculously big muscles. I have to say, I think he is the biggest nerd I have ever seen...on the internet.
- inactive, on 01/31/2008, -0/+1It as been said that liquid and hair are the two most difficult natural occurrences to simulate. That was almost 10 years ago and this is some fantastic stuff.
- wdfadude, on 01/30/2008, -1/+2Okay, this is one field I'm admittedly not an expert in, but hasn't there been realistic-looking CG water in movies for years? I can count more than a handful of movies from 8-10 years ago that had this kind of stuff. Hell, even some of the best early CGI F/X from the early '90s were the "ocean ripples" effect.
- Shiftgood, on 01/30/2008, -0/+1nice website layout. Now i know where to go for all the information ever made.
- xpankrat, on 01/31/2008, -0/+1That's Ron Fedkiw, ladies and gentlemen. A man with a dream job :)
Recalling what they taught us back in the Uni, the discretization of Navier-Stokes equation, which is essential for realistic fluid and gas animation, is tricky to put it mildly. Coming up with the algorithms that can actually run in a .. hehe .. finite time is even more complex. But without these CG FXs would've not been anywhere close in realism to what now we routinely see in the movies. - hollerith, on 01/30/2008, -1/+2"George Lucas made Star Wars and, well, that changed the world for a lot of us," he said. "It's amazing what a movie can do to a civilization. I can only be grateful that he made three more of them and that I started working with ILM just in time to get a screen credit on the last one."
How old is this? Hasn't there been six yet? ...damn microsoft time machine. - 0ceanic, on 01/30/2008, -0/+1another vote for some high quality vids of this specifically.
- rune420, on 01/31/2008, -0/+1Those are some pretty awesome simulations, but I think the real brow raiser here is the mantasuit.
- xpankrat, on 01/31/2008, -0/+1No offense, but .. yickes !
- MikePricee, on 02/19/2009, -0/+1Computer Scientist Nets boy friend.
http://www.unlockcomputers.com/ - LJRod82, on 01/31/2008, -0/+1Video games are pretty close. Half-Life 2 and Bioshock come to mind.
- schallis, on 01/31/2008, -0/+1Sheffield Hallam University's "Thinking Water" technology was used in Super Rub-a-Dub. It's pretty realistic.
- VideoDoc, on 01/30/2008, -0/+1Whole computer graphics science stands behind Hollywood, no doubt. VideoDoc was always amazed by those stunning effects and all this CG stuff - computer graphics are indeed a triumph of computers,art and math sciences!
Interesting, in which software does all this stuff come integrated - Maya, 3ds Max, Lightwave, Blender or all these brand simulation stuff goes to some unknown Hollywood software? - almondfilter3, on 01/31/2008, -0/+1Um no its not?
- svander, on 01/31/2008, -0/+1You weren't; I almost dug down the story because of lack of video on that website.
Diggers came through with the goods again! - deeringc, on 01/31/2008, -0/+1This stuff is really cool! Reminds me of one of the Professors in my Uni who won an Academy Award a year or two back for his with work with the Foundry... http://www.rte.ie/tv/scope/SCOPE4_show05_cuttinged ...
- Audacitor, on 01/30/2008, -1/+1If you'd tried to render this stuff 8 years ago, you'd have been waiting years, not some skinny little month.
- NikoKun, on 01/30/2008, -1/+1too bad this kind of super realistic water STILL hasn't appeared in any videogames
- adjo, on 01/30/2008, -0/+0Must be the year of the fluids. Next Limit's Real Flow won the Academy Award for Technical Achievement. Some amazing fluid simulations:
http://www.fusioncis.com/about/press/realflow/ - xaxxon, on 01/30/2008, -1/+1Nope. Only 3. And I'm not even sure about the end of the third one. Why does a wookie live with ewoks? It just doesn't make sense.
- LeeSoong, on 01/31/2008, -1/+1'shopped -- the reflections are all wrong...
- Thrilltone, on 01/31/2008, -1/+1I tried to make some 3D water 6 years ago.

- bent3d, on 02/03/2008, -0/+0I actually own RealFlow 4 and have some experience with it.......I see some people asking when we'll see this in video games...I'm guessing not anytime soon!! The reason being the effect has to be setup inside Realflow. Which is a stand alone application, and separate from the main 3d package being used for the games creation (3d Studio Max in most cases). This is complicated as there's a whole wack of ***** that has to be set up. Although RF uses particles, everything is based on real world physics and scale. All geometry has to be set up as rigid body dynamic objects that can interact with the water particles and each other..weight, gravity, friction, elasticity, force, internal and external particle pressure, volume, density, etc... have to be simulated per frame and cached out to disc. This can be a very slow and CPU intensive process. Complex simulations for film can take days or in some cases weeks to process. After that a 3d mesh is generated based on the position of each particle in XYZ space per frame. The mesh then has to be exported out and into the 3D package being used. ...because of this realtime game interaction would be impossible using these techniques. Not to mention the fact that truly realistic water is mostly based on the material and lighting, not just the movement. For CG water to look realistic, a pretty complex shader has to be applied incorporating reflection, refraction, subsurface scattering and caustics, bump maps, displacement maps and or specular maps to get a somewhat realistic effect. All of these are slow rendering and are usually passed out for later composite. Not exactly ideal for games.
So to sum things up...The current hardware available to gamers is just too limited to support these kinds of effects. Even top of the line computers built specifically for CG professionals are pushed to the limit working these kinds of complex effects...
But if you want to see some fluid animations, Here's a link to the showreel for RealFlow 4:

Cheers, - postitnote, on 01/30/2008, -2/+1go go power rangers!
- mal1964, on 01/30/2008, -3/+1Scabs!

- JustinHorne, on 01/30/2008, -7/+4This was a little weird until I realized it read "Fluid Simulation," and not the "Fluid Stimulation" I had first read it as.
- SAKevin, on 01/30/2008, -3/+0Um, this link is worthless without video?
- inactive, on 01/30/2008, -7/+2Is Duke Nukem Forever really coming out by christmas?
