6,000,000+ Particle Water Realflow Simulation HD

[MrTarkooka]

in 4 years you'll be able to do this on a smartphone :P

[em042496]

@deathsminion25 well if your talking voxels that may work but for 7mil particles just for one animation voxels will break down really fast the amount of RAM that you need would just be insane

[Lougikiro]

Why does this water look more realistic than the water that comes from my tap?

[Bora4D]

Looks like S******m

[superbungabunga]

cant wait till they have the power to put this physics in a game, would be badass

[MrEmaxxfreak]

how long it took to render?

[brandonse167]

ok, so im a 100% noob to Real flow and what i don't understand is why it is that everything is just huge blobs ive tried to set the number of particles higher and scaling down the whole project but i cant for the life of me figure out how to get nice, fine particles like yours

[cevune]

cannot wait until technology gets to the point that something like this can be rendered in real time

[FruityLoopsification]

@cevune 10 years maybe? you never know what advancements are gonna be made

[deathsminion25]

@cevune There already is technology that can render this in real time.

[bnewton81]

3.5 years to render

[BenjiKersh]

rendering time:5.2 million years

[androdriguez1998]

How did i get from watching skateboard accidents to this

[ArcadeGames]

I'm thirsty now:)

[STAMessias24]

Cool, but life can render this in 14 seconds!

[entheogenetic1]

gasp

[Waldituned]

IT´S OVER 9000 !!!!!!!!!

[Qzyxya]

Beautiful. How much does realflow cost?

[theAlijan]

i bet you anything his name is bob.

[zmallic]

Excuse me , But you mentioned in the description over "200 gb for simulation" , are u referring to the size of the final file ? Or something else ? Please explain , thanks 

[bobbbyyy1]

@zmallic

The simulation files created by Realflow took up 200gb. The final video file was only 1 or 2gb.

[LxrKan]

@bobbbyyy1 clearly you need to learn to export video more effectively if its only 14 seconds xD



[animajdb]

@zmallic Realflow Caches the simulation. those cache files are HUGE. I had to buy a 2tb eternal to do all the simulations i want. I did one 8 seconds, 90 gigs in just cache files

[NOLIMIT69NOLIMIT2000]

Over 9000

[Zemlin]

10 days later the render is finished

[LAUZERTV]

Is this guy called Bob or something? I could only just about make out the subtle logo ;D

[rayjohn551]

doesn't really look like water

[beanzton1]

ok i haven't been using realflow for very long but here is one thing that i have realised. u don't really that much particles for a small scene to achieve realistic results. U probably would have achieved the same results with under a million particles.

[bobbbyyy1]

@beanzton1

You might get away with it if you used about half the particles, but you'd certainly see a difference in quality with under a million.

[deathsminion25]

@bobbbyyy1 What are the intended dimensions of the domain of the water?

[NathanIcon]

@bobbbyyy1 Question... How do you texture the water??? Please reply, because I have RealFlow V5 2012 Pro Licence and I am learning... :)

[Larty42]

This method can simulate as many particles as C3PO understands alien languages.

[Hitslide]

IT'S OVER 6 MILLION!

[rysliv]

hah computers are ridiculously slow.

[3Deity]

@rysliv Two years ago some researchers cracked the optical computing problem. The CPU couldn't do much and was large (10mm diameter) but it produces no heat and has a basic operational speed of 17Thz. To put that in perspective, thats the speed difference from 15 years ago to now extrapolated. With this power, you'd never use OpenGL / DirectX but multi bounce radiosity all the time.

[bddblade]

Looks delicious :]

[bobbbyyy1]

@bddblade

Thanks!

[iceman78772]

@hellyesvetica Light goes through water.

[MaxArceus]

uhm (this feels kinda strange to say but eh) water isn't blue..

[sockschappercat]

@MaxArceus It is, but very slightly. There's a reason that the ocean is blue.

[MaxArceus]

@sockschappercat The reason that the ocean is blue is because blue is the only color that doesn't get filtred away when light travels through the water. So yeah I suppose you could call it blue, but the amount you have here in this video isn't enough to get that effect.

[NexonPlayerNA]

@MaxArceus Wow, you're both wrong. Water's blue because of the reflection of the sky. If it didn't reflect the sky, then the ocean would be brown and yellow because of all the minerals and fish shit. Adding blue makes it green.

[MaxArceus]

@NexonPlayerNA Then why are deep sea photos always blueish while the lamps that (try to) ilumante the setting give white light. Because all the other colors get filtred out. The fact that the sky is blue probably helps with making the sea look blue. But I've seen the sea many times with a cloudy grey sky, and it still appeared more or less the same color, blue.

[NexonPlayerNA]

@MaxArceus I just figured out that we're both right. The sky sends white light down onto the ocean, and BECAUSE OF the minerals in the sea, it reflects the light that is not absorbed: blue green light that becomes very dark and deep when it reaches meters of death. Whether the sun is out doesn't matter: it still sends white light into the ocean which is reflected into our eyes. The sky also affects it: blue light reflects off the sky off the sea and into our eyes. Diffusion at its complexity.

[NexonPlayerNA]

@MaxArceus It's a combination of all of our arguments. Huh, that's how it normally works in scientific, theological, mathematical, and political debate.

[sockschappercat]

@MaxArceus No, obviously not. Perhaps it's Powerade?

[00Kirby0]

So you spent several days, and a file the size of an average hard-drive, just to upload it to YouTube and put a HUGE WATERMARK OVER IT SO YOU CAN'T SEE THE ENTIRE SIMULATION.

Nice one.

[maudaros]

@1Mperios just look at the tittle

[maudaros]

water is tranasparent

[loosiipoosii]

how can i get this effects for after effect ???

[bobbbyyy1]

@loosiipoosii

I'm afraid there's no way to do that currently. Thanks for watching

[80LoveLess08]

@loosiipoosii Your going to have to get Cinema 4d or 3d Studio Max, they both render in 3d. After effects renders in 2d, but you could still find something that should get you something fluid like. I know after effects does have a lot of particle based plug-ins. Cheers

[fireflambe]

@loosiipoosii lol are you seriously asking how to render a 3d fluid simulation using a program for editing videos?

[loosiipoosii]

can i use this for after effect ?

[vDuoHD]

oh wow, record this in realy life ... it'll be even more realistic then x)

[bobbbyyy1]

@Destructor129

New rendering software is eventually going to incorporate GPU+CPU rendering. There are a few out already but its still in its early stages. I think once the popular renderers start using it, the render times are going to drop a lot. it would be amazing to see this kind of scene get rendered in realtime, maybe in a few years. Thanks for the comment

[Pestinha92]

Imagine this in a game... would take a generation or two to load a single map.

[wangtang32000]

several days to render 14 seconds..... *whine*

[FsimulatorX]

Please respond What CPU did you have and what ram?

[bobbbyyy1]

@FsimulatorX

2.4 ghz quad core with 6gb of ram

[emeanyack]

@bobbbyyy1 you didn't write your graphics card. Is it a high end one?

[bobbbyyy1]

@emeanyack

It's a 9800 gt. But it doesn't really do anything when simulating or rendering these videos.

[iep4b]

that's a little to much viscosity for water, it looks more like rapidly falling paint in slow mo

[henriquegomesHD31]

Why it looks like it's in Slow Motion?

[bobbbyyy1]

@henriquegomesHD31

it's simulated to be half the actual speed

[henriquegomesHD31]

@bobbbyyy1 Oh, Thank you. It's cuz, almost every realflow video i see is in slow motion!

[sneakySniper74]

how did you make a constant flow?

[bobbbyyy1]

@sneakySniper74

I think it's because of the smoothing value used for the meshing

[chipaputalaguea]

@sneakySniper74 emitter options, theres something called stream should be yes

[managarm1349]

pretty epic, what hardware u got?

[bobbbyyy1]

@managarm1349

Thanks! Its a 2.4 ghz quad core with 6gb of ram

[thestriker890]

awesome!!!!



[bobbbyyy1]

@thestriker890

Thanks!

[TheLegitDiamonds]

14 sec, 10 Hour render :D

[Sam737loverfsx]

What program are you using ?

[TitanaMaster]

you did great job here man! keep working on it...

[bobbbyyy1]

@TitanaMaster

I appreciate it!

[legoneurt]

You are awesome

[bobbbyyy1]

@legoneurt

Thanks!

[Markus9705]

Several days and 260 GiB? Wow!

[Pestinha92]

Damn, if that's 12 seconds of water and it weights 200gb... imagine if real life was a computer o.o

[afker553]

link to download please

[Berniebud]

@afker553 He deleted the file because it took up too much space.

[afker553]

@Berniebud so what

[Berniebud]

@afker553 You asked for the download?

[afker553]

@Berniebud @afker553 2 weeks ago ..... so don't bother me anymore dude

[TheARCM]

great!!

200 gb for this omg...............

[bobbbyyy1]

@TheARCM

Thanks!

it's too bad those 200gb had to be deleted after rendering

[b1tTutorials]

@bobbbyyy1 why it would cost only 6€ for the hdd

[bobbbyyy1]

@b1tTutorials

Saving it on a different hard drive is an idea but even if I had the files, I don't think I would have time to go back to it and render the sim using a different camera angle or make some small change to the scene. It's too bad that all that information is deleted, but it makes room for new simulations (which happened to be the 8.5 million particle sim that took over 400gb of space)

[Ipodtouchmaniac100]

cool! also please check out my video, i have an awesome fishtank simulation

[bobbbyyy1]

@Ipodtouchmaniac100

Thanks for the comment!

Cool simulation you have. I've not tried Maya fluids. How long did it take to sim and render?

[Ipodtouchmaniac100]

@bobbbyyy1 3 days :P I have an old computer in my basement that i render with because my sister sometimes shut our main computer in the middle of a render :(

[PureRecordz]

Congrats! Great result considering you used mentalray!

[bobbbyyy1]

@PureRecordz

Thanks!

[bobbbyyy1]

@RazaKator

Mental Ray

[onlyCreativity]

that was great, nice to see other people being "high res simulation" freaks like I am. I liked. :D

[bobbbyyy1]

@onlyCreativity

thanks, i like your high res simulations too!

[rammbostein]

I like it

[bobbbyyy1]

@rammbostein

Thanks!
