State-of-the-art graphics reveal vortex physics

[valllhalla]

you don't want to destroy them... you can use them and make the aircraft go faster.

[brian21281]

as an angelic shaman, it's the only way to travel lol 

[mast3r0fr0b0ts]

Now my brain hurts from looking at the comments :'(

[SporeCoreMore]

GREECE FOR EVER DUDE!!!!

[dtiydr]

I want that program.

[chica2086]

You can't destroy it - - why would you do such a thing - - energy can't be destroyed!!!!!!!!!!!!!!!

[haeresy]

dam todays scientists have it backwards, don't try to destroy vortexes, use them to your advantage as they are centripetal based, energy that builds on it's self! Todays science is all based on explosive centrifugal force which destroys itself once reaching the outer confines.

Vortex centripetal technology is nature and explains many things from water to flowers. Humans took the wrong path in developing centrifugal and explosive energy but hey more money in that right?

[Dvoracekmara]

Hello, nice videoo!!!

[bad7trip]

Μπράβο Πέτρο! φαίνεται απ την εξομοίωση πόσο πιστικό είναι το αποτέλεσμα. Ο κώδικας που χρησιμοποιείτε κάνει θαύματα.

[Adeptmind]

@bad7trip i dunno about all that.. but getting close

[dawoof]

awesomes

[qwecjc]

i am glad you feel that way

[pockmarkedbuttocks]

ok, it's actually pretty cool! ;->

[tenisplayaz1]

cool

[slappy480ic3f4]

that's like totally tubular!!

[sirnicholson]

funny."state of the "art" everything on this channel is art work.the future through the eyes of an artist.

[sobeita]

Art and science converge relatively often, since art imitates reality and science models it.

(State of the art doesn't mean artwork, though. It's an expression that means "up-to-date.")

[anxietydeath]

My video games look better!state-of-the-art my ass.

[deby1392]

grow up

[ultratacoRX7]

Your video games don't simulate fluid dynamics.

[LokiClock]

Actually they probably do, given the number of games that implement fluid dynamics even just as a visual effect. I, as am amateur programmer, appreciate this research quite well enough, and I'm sure the people who can make better use of it appreciate it even more.

[bramiozo]

You can't say that they 'simulate' fluid dynamics as they only want to mimick certain characteristics, if the player thinks he sees a flow it is sufficiently accurate.

Fluid dynamics in games and the CGI in movies is usually thoroughly simplified, because of the complexity, the resource requirements and the fact that numerical stability should be guaranteed for user experience, the latter is impossible.

[LokiClock]

Simulations are by their very nature only approximations of real things by what characteristics are necessary. You can never know every single thing about the object. So you're working with symbols of the object.

[mckseal]

i havent yet seen a game with real time fluid dynamics, it is not possible with current technologiy

[SpikeTheSpiker]

@mckseal it is possible, there is a game being made that bases its storyline around real time fluid I can't remember the name though sorry dude.

[mckseal]

heh, would love to see that...

im currently making a game with a research company... its physics based so if course ive looked into this. Yes, using Eulers physics we can get some fluid dynamics and, if we used the graphics card instead of gpu (think physx) we have managed to animated it realtime. But there are too many bugs for our small company... we probably need help from somebody.

[mobius1aic]

Depends on how far you need to go with the fluid dynamics. Available technology can do quite a bit, but not calculate every single molecule in a real time CG scene.

[zhuldjinn0013]

The Reynold's number in 3D. It will be useful form thermodynamic research.

[threelegduck]

the holy grail in the field if to figure out why the vortices always spin counter-clockwise (perpendicular to the angle of dilation)

[splashon7]

get off the drugs rooster

[alexgee86]

type in "a new kind of science" on this subject, it's the best video i've seen on youtube

[alaniarisalfistas75]

he is greek....yeah..auta einai re..pantou einai oi ellines re..parte to xampari...!!blaaakes..!!

:D:D

[maucaldosa]

very informative... nice video...

[10m19l92o]

shes a witch! burn her! burn her!

how do you know she is a witch?

we.. well she looks like one!

i am not a witch, they dressed me up as one!

did you?

no... n, no. ok yes we did... burn her anyway!

[omgr0ckorz]

so if she weighs as much as a duck, shes witch?

[10m19l92o]

Who are you so wise in the ways of science?

I am Arthur, King of the Britons.

My liege!

Will you join me on my quest for the holy grail?

Of coarse, my liege!

[britoca]

witchcraft! WITCH!

[rocketmen1]

that would be really cool to use that in the video game bizzz

[ChaChinnngK]

To numb more minds ? Nah better put it to better use.

[KritikalDimensions]

Volume rendering is used by directX 10, if you get a dx10 compatible graphics card, alot of the newer games use it for water/smoke/explosive effects. And video games do not numb minds chachingk, I have been playing shooters for years and I am still horrified by the anti-terrorist propaganda.

[ChaChinnngK]

Obviously not everyone is affected but many are. It's neuroscientifically proven (just look up the connections they have found, how it desensitizes observation, teaches how to minimise empathy, on a non conscious basis etc, lessens the attentionspan to everything that doesn't bink and whistle like a gabba track etc).

[ChaChinnngK]

bink = blink

[ChaChinnngK]

Anyway, this video is tied to something completely different, so keep daft and visually unappealing computergames out of it.

[OpenEyeVisuals]

fancy pants cosmetic engineering... okay it looks hella fuckin balls-to-the-wall awesome

[sodiumbenzo8]

i hope i'm beat'N-off @ the right nuance -jk!!

[Koroush51]

So you rude youtards want me to believe that if a butterfly flaps it's wings at the wrong second an earthquake happens in china.

Thats why i say it's bs.

[Paulginz]

Let me explain the butterfly effect:

A chaotic system is a system where a tiny change in the initial conditions can produce a huge difference in the long run.

Meteorology is such a system, and the famous analogy is that a butterfly flapping it's wings could cause a hurricane a week later. (not an earthquake)

The key word is COULD.

This effect was noted when a meteorologist fed his data into his model, and got completely different results because he had rounded an insignificant digit.

[zakattak80]

that sounds cool but i it sounds like a pretty outrages claim

[nandoanalog]

you can`t be that dumb...

[Koroush51]

Chaos theory is BS. IMO

[yablebab]

Way to argue your position, professor.

[hamsterpoop]

nigger

[LegendSaber]

Chaos theory is a proven scientific fact numbnuts.

[Koroush51]

Interesting.

I wonder why they still call it "Theory"

[LegendSaber]

Because something can be both a theory and a fact at the same time?

Geez, sounds to me like someone needs to learn a little basic science. :p

[hamsterpoop]

wow, there are still morons who havent noticed that everything in science since more than 100 years ago has been called a theory instead of a law... way to be up to date asshole...

[LehdaRi]

agree.

[mf0rz]

... that explains the 3- dimensional alphabet.

[Ariji86]

...

[bimblinghill]

Sexy science! It blows my sorry ProMechanica work out of the water!

[turtalako]

state of the art graphics?

wow .. these guys has got to play Gears of War .. or atleast watch a Quickening move in Final Fantasy XII

[InTheCity3D]

No offense buster rhymes video games player, but you're missing the point entirely. They're not talking about graphics from the perspective that you're thinking of, but real time volumetrics. Something that in the long run could benefit games, as we rely largely on 2.5d graphics in games for explosions et.

They're talking about actual physical 3d volumes, the easiest example being a full fledged cloud and its inner dimensional structure.

[inthefade]

The ability to predict the way a chaotic system like a turbulent vortex is not only amazingly useful, but it is shockingly difficult. Better understanding chaos theory may be one of the more important scientific developments that happens in our lifetimes.

[Astrocopus]

as in the ocean...JUST a Rossby number of the order of unity..

[tanginumin00]

cuz the world is bigger than that of videogames

[ChaChinnngK]

Not to everyone..

[serloinz]

hope yer bein sarcastic ;p

[CCPnoob]

no offense turt - but these are not pre canned video games in this the main thing is the physics of being able to track millions of particles at once. FAR FAR more advanced then any computer game.

[ChaChinnngK]

No one with an ounce of aesthetic sensitivity would want to watch that crap ("Gears of War" "Final Fantasy XII").

[ChaChinnngK]

Sorry red person, but it's true

[ronnieboy3]

Hey dumbass,

It takes a computer millions times powerful than the one you use for gears of war to calculated the vorticities.

[frogscar]

Nvidia Graphics of course

[TurboLoveTrain]

Whoa!

[djindio555]

:-)

[popecorkyxxiv]

I love this channel, so many nifty new inventions. Day by day the term 'Deus Ex Machina' becomes more and more literally true. (FYI Deus Ex machina is greek for "God come from the Machine")

[Qlkjsdo]

Latin actually :) And historically it's not really related to science or machinery...as far as I can recall it has summat to to with theatre.

[popecorkyxxiv]

Actually it is Greek in origin, it was a literary/theatrical term relating to a plot device that is out of context to the story that resolves a major plot point, expressed usually in theater by an actor portraying a God being lowered onto stage on a crane or gimble (hence, God come from the machine). The Latin language has it's roots in Greek, as such many of the words tend to be repeated over the two languages, Deus in Greek for example means God/Zeus and in Latin it means deity or divinity.

[Qlkjsdo]

The phrase might have its origins in Greece, but the language you quoted it in is Latin. I don't think it's that closely related to Greek actually, as I've had both at secondary school and experienced they differ quite alot.

(Why am I doing this? Your point was clear anyway and this is completely unrelated to it...ah well)

[Astrocopus]

Vortex methods for incompressible flow simulations ..Petros Koumoutsakos does SOUND Greek

[alaniarisalfistas75]

he is greek..xexe..

[ScottishAtheist]

Science wins.

[syaoranpies]

reminds me of the kamehameha

[OneMove33]

huh really... to me it looks more like the special beam cannon!

[Reav420]

keeeeeeeeeeeewl

[int3rl0per]

The resolution of the graphics is pretty amazing - if I were to do that, I'd create a huge particle field (for representing the data points) and interpolate and approximate camera-facing planes between the points of the resulting splines.. However, it looks like they've taken a wholly different approach. Then again, if it's not realtime rendering, none of it really matters to me. :)

[Richardgwm]

Religion is the source of all truth. Science has never achieved anything. Religion brought us penicillin and the jet engine. What has science ever given us? Nothing. Religion put a man on the moon and created the internet. Heck, science could not even keep Terri Schiavo alive when religious life support was withdrawn.

[spiritpunker]

What are you babbling about, sir?

[int3rl0per]

He's trying to point out the bullshit of religious zealots trolling Youtube's science channels.

[noinlair]

Satire ...

Doesn't translate well over the internet.

[ssnatcherss]

Nice satire ;)

[johmey25]

this is alot better than the homosexual insects

[GetMeThere1]

Nah. What I want to see are the turbulence vortices produced by humping insects. Now THAT'S science!

[shobhitg]

Now thats kind of stuff what I expect from New Scientist!

Thanks for sharing!

[SilverGunZoO]

cool

[rotatingwah]

absolutely slick! wonder if the mandelbrot set plays any role in this technology....hmmm

[thebigcrap009]

cool!!!!!

[minomeshank]

FIRST!
