- chrismear, on 10/12/2007, -0/+3The problem with this animation is that the fluid is too viscous to be water. It looks like baby oil or something.
Also, it doesn't break up properly. When portions of the liquid come up the side of the glass, they should break apart into droplets and smaller pieces of water. - ashtonium, on 10/12/2007, -0/+2yeah, it's so close that the slight dissimilarities from reality start to become more evident. I think the main thing that makes it seem less than real is that the water source is so consitant and unwavering.
- mrbinary, on 10/12/2007, -0/+2Here's Ron Fedkiw's actual site:
http://graphics.stanford.edu/~fedkiw/
It has over a hundred movies, most of them much more unique than the one dugg. - matid, on 10/12/2007, -0/+1I dugg it, but I'd rather say that's because of valuable comments that led me to Ron Fedkiw's website.
- firebeastm, on 01/17/2008, -0/+1You can download this video at http://www.freeyoutubegrabber.com/
- Manzabar, on 10/12/2007, -0/+1I agree with tamzarian that it's cool but does not quite look real to me. Though I have 2 thoughts on why it looks a bit off:
1. The speed of it seemed a bit too slow to be water pouring into the container.
2. The fluid bounced up & around higher in the container than I would expect water to do. - waaalrus, on 10/12/2007, -0/+1I dugg this because I recognized the video from a lecture given several years ago and it was weird to see it in a more "popular" venue. Doesn't everyone realize the video is a demonstration of computer algorithms he developed (or helped to develop)? If his web page was designed for popular consumption (and he had the time or inclination) he might put the dates the various simulations were created. Even so, you can tie the videos to the publications listed at the bottom of his web page if you're interested. Explicit dates might save comparisons by casual observers with more recent techniques. My favorite is the mention of Nils Thuerey's work with Blender. If you look, the same research that created this particular video is referenced in his publications. It's mentioned in other comments, but Ron Fedkiw's web site is:
http://graphics.stanford.edu/~fedkiw/ - ghelton, on 10/12/2007, -0/+1anyone can do this with blender its not really that hard, and ive seen better examples
http://www.blender3d.org/ - Starskey, on 10/12/2007, -0/+0It's facinating, but doesn't look really like water. There are some basic properties of water displayed quiet well, but there's still a ways to go on that one.
- deuteron, on 10/12/2007, -0/+0Yep, we're getting closer, but still looks a bit like "Crystal Gravy" from SNL. But since I know how hard this stuff must be to do, I have to say it's getting better all the time.
- jmorrisseyd, on 10/12/2007, -0/+0not sloppy enough but actually quite amazing
DIGG!!! - FunkyG, on 10/12/2007, -0/+0It is pretty cool, but not very realistic. The water jet just stops and spreads for no apparent reason, and there is way too much 'sloshing' for a flowrate as shown that is poured down the side of the glass.
CFD is great, but it is only as good as the mesh and user experience. Check a guy like Andre Bakker from Fluent if you want to see some really cool animations. - IniNew, on 10/12/2007, -0/+0If you go to ttp://www.cgtalk.com there are many animations of the same thing.
- scottym, on 10/12/2007, -0/+0Yeah, I'll go with oil. Kinda cool.
- Jozer99, on 10/12/2007, -0/+0Relax guys, I think it was running at like 50% full speed, so you could better appreciate the realism. My only complaint (besides the VERY laminar pouring) was that there should be some droplets breaking off the "waves"
- knightmare, on 10/12/2007, -0/+0that is some thick nasty water...where is the splash?...not real looking...no digg
- daboy, on 10/12/2007, -0/+0come on. Blender had this ability back in October. AND it's free. you just need a lot of hard drive space for the simulation to do its calculations.
documentation here: http://mediawiki.blender.org/index.php/Manual/PartX/Fluid_Simulation
MUCH better than this professor guy's. - thenet411, on 10/12/2007, -0/+0Looks like clear oil. I wouldn't want to drink it.
- zzz@tkz, on 10/12/2007, -0/+0Yep, oil.
- neilpan, on 10/12/2007, -0/+0hmm... cant wait till i get to take "fluid mechanics" :) .... prolly in about 2 semesters :)) .... pretty cool animation... +digg
- MrKite, on 10/12/2007, -0/+0No one would know it was fake if they weren't told that it was a simulation. So all you "it doesn't look real" people can KMA. I think they did a great job with this.
- CanuckPlumber, on 10/12/2007, -0/+0Uncanny valley
- tablatronix, on 10/12/2007, -0/+0yeah definetly looks like mineral oil
cool nontheless. - pheifdog, on 10/12/2007, -0/+0very realistic but there is one MAJOR PROBLEM... there are no BUBBLES when pouring.
- inactive, on 10/12/2007, -0/+0That was lame, I'm gonna give it a thumbs down, it looked like oil, not water and it lacked any bubbles that comes from pouring water into a glass that fast. digg--
- Aamir, on 10/12/2007, -0/+0Yeah usually bubbles form when the water is pouring, nice find though
- TheCardinal, on 10/12/2007, -0/+0Needs bubbles.
- rezophonic, on 10/12/2007, -0/+0The biggest thing I noted was that the water didn't interact with the container at all, videlicet leave behind little droplets or form a meniscus.
- rimco, on 10/12/2007, -0/+0It looks like oil, not water.
- TimmyK., on 10/12/2007, -0/+0Nice, but I agree that it's too viscous looking, especially at the end. It looks like waves in a lake, not a small glass. And where are the bubbles? Water being poured like that would have bubbles in it until it settled down.
- phuqju, on 10/12/2007, -0/+0where is the splash
- ohfivepro, on 10/12/2007, -0/+0thats some thick a$$ water...bet they used vegas water as a model.
- Naruto28, on 10/12/2007, -0/+0Neato. However, those flowlines clips are badass.
- xavi, on 10/12/2007, -0/+0it looks like clear jello
- AmZa, on 10/12/2007, -0/+0man...that made me thirsty.
- jumjum, on 10/12/2007, -0/+0My Alienware didn't do well at all with the latest 3dMark, I figured I could skate by a few years without having to buy anything, but I guess not.
- mikeazorin, on 10/12/2007, -0/+0The one problem is that the water only has visible currents at the top, the stream is too consistent, and the stream ends without any slowdown.
- inactive, on 10/12/2007, -0/+0It is in slow motion, but the movement is still too exagerated. Cool though.
- scott1, on 10/12/2007, -0/+0That is cool!!! It looks very realistic!!Too bad in 20 years it will be outdated and internet historians will lagfh at our comments about how cool it looks.
++++Digg - Zippo, on 10/12/2007, -0/+0The slow motion makes it look fake... or a lot thicker than water.
- Wardvark, on 10/12/2007, -0/+0should have bubbles and when it sloshes it should leave drops
- Yoda716, on 10/12/2007, -0/+0Man that looks pretty realistic but can the user interact with it in a video game? Can I throw a box into the water and in real time see the displacement?
- daboy, on 10/12/2007, -0/+0one more thing: the code used in blender was created by Nils Thuerey, here:http://www.ntoken.com/p_fluid.html
even more awesome examples - vermin, on 10/12/2007, -0/+0Ya, the flowline is a better simulation.
- salmonmoose, on 10/12/2007, -0/+0This looks terrible; If you think it looks good, you should look at both flowlines, and realflow's web pages, as have been linked to a dozen times already;
Also check the 2004, and 2005 siggraph showcase dvds, there's some impressive fluid simulation on them. - doles, on 10/12/2007, -0/+0Do it in real-time, then I will be impressed. For now its just like every other SPH or Eulerian fluid demo floating around the academic community.
- felchdonkey, on 10/12/2007, -0/+0@antbloor - (and everyone else who put up the flowlines link without reading his comment)
That's fricking AMAZING. Entirely CG?
Eff the glass of castor oil being poured, I'm going to go watch the shark again... -
