Particle-based Viscoelastic Fluid Simulation

[SOFTPOISON]

super demostrativo!

[jadzia2009]

I liked the cow.

@arkano22, I also found it very stable. However, part of stability comes from the fact that position and velocity for each particle is updated sequentially. If the method is changed to update particles in parallel based on positions from last frame it becomes unstable. It may not have been an issue when the paper was written but this paper seems hard to implement on a multicore CPU or on the GPU.

[arkano22]

I only wanted to thank you for this method which has proven to be very useful to me. I implemented it on iPhone (2D) in a weekend, and it outperforms all other SPH-ish implementations I tried, plus it looks good and is incredibly stable.

Again, thanks. Keep up the good work!

[MangaRED]

wow man that's very realistic!! when you say particle based means that the fluid is a sum of individual particles?? was it fast to see? or it took some time ? i imagine that alot of particles means alot of calculations for the computer... very good!! i hope to do something like that someday! for now is 2d mechanic sims for me

[spider853]

So cool ) Blob mesh and sim + physics are great

-nazi smashes rabbit and then gets ownd- I TOLD U DONT SMASH THAT DARN THING, THATS WHAT YA GET :D

[OniLink10]

Hooray for various random viscosities!

[ecxlex]

this blendder or application?

[ulkord]

cumshot jeah!!!^^

[MrPablowjob]

now you can make realistic cumshots on fake japanese animated girls with big tits!!! FUCK YEAH!

[sasasasa34]

HELL YEAH!

[yarloo]

Omg my thoughts exactly.

[Jallenbah]

I lol'd when the foot smashed the rabbit.

[TheFrankenstein001]

nice green jizz :)

[Eralen00]

boom headshot

[Vikinatorn]

Poor bunneh :O

[rjfire]

hooooooooow do u do tht plz tell me

[ejay201]

it looks like a pee lol

[DesiScientist]

marketing propeganda.........numerical methods have lot of flaws still

[luketheduke0]

DesiScientist, what do you mean?

[DesiScientist]

meaning to say that code/software makers love to tell you all the fancy stuff. what they don't tell is what these codes cannot do!. Free surface effects are still not predicted accurately even by the most advanced flow simulation codes. See when i commented 'marketing propaganda' some sales person immediately marked it as spam lol.

confused? ask me more and i will give you details in numerical terms!

[FUNNzilla]

why are they using the same models (stanford bunny, utah teapot, cow) for decades in university papers? lol i must admit i had never seen that dictator before! Is it a cartoonish Benito Mussolini?

[jojodi]

In SIGGRAPH some years ago, there was a discussion that led to the consensus that the community needed some standard models for comparing things. Things like the Stanford bunny and cornell boxes are used so that you can test many different methods on the same model, often to test experimental ideas and meausre their performance on previous ideas/techniques.

In short words, they provide a start for benchmarking techniques. (They're also free, which is handy!)

[DesiScientist]

and changing the model would reveal many other flaws of the code!

[Narcis6523]

OMG that cow ROKS!

[owchywawa]

LOL!

[walikai]

is this realflow? or blender? or what plz reply

[Asdam12]

Is this real-time?

[axrarx]

that poor rabbit :[

[OGMO11]

I totally agree... why not take a uuuh... well... nothing deserves to be covered in green goo

[axrarx]

it looks lewd

[luketheduke0]

I am having problems interpreting the double-density relaxation. I went ahead and tried how I thought it would work, and the particles bunched up. Also, they stack on one side, leaving the other side empty. I'm hoping someone could help me.

[luketheduke0]

I had the same problem. I found that instead of following the paper exactly, you see the general way it works, and then make your own code. I spent a month working on it(I had no previous experience with physics).

[TechDawgJr]

can you send me the download link

[hollowinichigo]

lol slime! :P too bad we couldnt have this in a game already and if we did we would want some kind of slime gun to shoot stuff i'd be realy fun

[Asdam12]

Is all this realtime??

[toamaori]

man that stuff looks good enough to drink or eat lol i laughed whrn the colonel got knocked over lol

[matt1746]

The cow at 2:00 made me laugh.

[wakeupfist]

Wow! Was your inspiration Ron Fedkiw?

PS. This must be how the Grinch ejaculates :-)

[hycalvinc]

I am implementing this paper right now . . . hahaha . . hope i can still get some help when i get stuck :p

[Gamegeneral]

you could make an awesome first person puzzle game with this technology.

THIS POWER MUST BE USED FOR GOOD!!!!

[sts3234]

Was this made with Blender?

[notsowhole]

rabbit:MMM....GELATIN

general:NO!!! NO GELATIN FOR YOU!!!!

rabbit:HOW DARE YOU, TAKE THIS!!!!

you need to add that along with some more audio for this movie, and you did great on the fluid simulations

[7677890]

Poor rabbit!

[TNTorsten]

Hey, looks really great!

[carpenoctem66]

Goos job on this one! I liked the coding used for it and the object reactions!

[ArisSalonicaGR]

nice demo. ive tried fluid simulation myself once but i went for the navier-stokes approach. not particles. particles are better, in that there's no need for a computation grid (which is very confining to begin with) but NS solvers on the other hand are becoming popular because they can be implemented in the gpu now.

[masterchief3k]

NOOOOOOOOO MAI BUNNEH!! IT DEADSSS NOOOOOOO lol

[kotsoft]

i actually coded this in java a few months ago. i have some 2d real time examples on my website if anyone's interested. kotsoft [dot] googlepages [dot] com and go to the physics section.

[kiaranr]

You website is great! Your work on fluid simulation is an inspiration. I'm a graphics programmer myself just beginning to explore the physics side if things. I've previously been concerned mostly with deformations, not simulations.

[clavetsi]

Not real time. About 3 secs/frame for physics, 10 secs/frame for rendering.

[thefreeman00]

This is done in real time correct?

[clavetsi]

The code that generated these images are somewhere on my old computer, and sadly, it is exactly the opposite of user friendliness... It is in the "research code" category. At some point in the future though, I could find the time to make a real "software" with that. Until then, enthusiastic coders should read fluid simulation papers and try to reproduce this kind of result

(You didn't think I would give all the answers...)

happy coding!

[kjknohw]

"where do i dl this"

He means the SOFTWARE!

That wold be awsome to have the software to do this!

[PaeanBall]

You can search "Particle-based Viscoelastic Fluid Simulatio" through google and you will get it.

[supernick12345]

where do i dl this

[clavetsi]

This video is the result of my masters thesis. Check the paper for details.

[may9119]

good  what program do u use?
