Finally, A Blazing Fast Fluid Simulator! 🌊 

👌

XD

I went to school! That makes me a scholar right? *Right?* :(

dropped out and do not intend to study again, do I qualify because I'm a curious idiot still ?

@@sankhyohalder97 Maybe you have to go to a "scholl". That reminds me I've forgotten to do my German exercises today!

You are too kind Bernhard. Thank you so much! 🙏

Agreed

Ai breakthroughs grab my attention more often than fluid simulation but little by little, Two Minute Papers has worn me down and now I get excited for those too.

@@TwoMinutePapers So are there any softwares actually using this technique youre talking about then? Very misleading title if you dont actually share where you got all of this from

594k ** now 3 days later ;D

Completely agreed - absolutely incredible work! If you wish to see more, check this out. - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-goD36hVVl7M.html

@@TwoMinutePapers thanks! I had a look and wow; the paper and work in that is crazy, great stuff.

Magnetofluid dynamics are a heck of a thing

Well...THE time to be alive would be when all the physics and AI simulations show are mainstream happening at real time on videogames and such

@@estebansingh9411 I've been working on one with powered ragdolls in wind, and water that's part of the game mechanics, not just an effect, for 10 years as an experient, we called Kontrol and updated weekly for a while. Stopped. a few years back because of too few appreciated the challenge of wind effects and physics made it too hard to travel, and we had spent tens of thousands already just so creature didn't walk like a drunk. It's in 2d because we can see inside workings, there are allot of firsts, 3d oceans I predict in 10 to 20 yrs studios will do it more like kontrol does. THings like surfing on wind usign just air drag and friction, were discovered and I never felt greater thrill in my career than to see these things emerge, I tuned and shaped surfboards all night to see how they performed In stead of coding the behaviour, and the custom sparse air model I used is nothing like what can be done with modern pc or phone. I firmly believe all aaa games will use physics for all movement, include air and pressure with balancing robot controllers that can fall. Its a time when playing games will make u better at sports, not worse. I want to add fluids because they are so fascinating, especially vortices. In a year or so I hope to release an android update with vids on my channel. It's rough but playable now somewhat.

That’s gonna be fun in 2b2t

Imagine portal with constant tsunami, ohh I’m trembling just thinking about it.

O C E A N M A N

Shut up, it is a tsunami in Lego.

Bright future ahead. Imagine a Tsunami AAA game. We are one step closer to simulating the entire earth in all its glory. Even if not 1 to 1

@@kathoden135 SAO soon will be avaible in real life xd

@@sageofmugen1724 the problem is not the gameplay or world building; that can be done with some hard work. What is a a problem, is the hardware to play It.

@@AndoniOlea xd yes hardware must be run on thousands of Ultra super computer specialized on that game and related with each other through the internet and of course with our VR that can transfert all the information directly into our head through electricity without killing us YEAH that seems impossible But if you go back in time to the 1700 and you tell them that will be a talking bright boxes communicate with each others and you can do....) They will say IMPOSSIBLE so that's the bright side you can't expect what sciences can do in the futur

haha, flushed

@@arsenhere7020 it sayed at the bottom it was slo-mo

@@arsenhere7020 its written in the bottom that its in slow motion

31%

Fluid simulations never look real to me, they always seem like they're happening in slow motion. It may be because there is no frame of reference for how much water i am supposed to be looking at. Like am I looking at 50,000 gallons of water or am i looking at a liter of water.

@LapisSea please do

I haven't read the paper, but implementation uses NVIDIA GVDB Voxels, which would be NVIDIA GPU only. In order for something like this to be added to blender it should be compatible with all common GPU's. I'm not sure if you can do sparse grids in like OpenCL. I don't have any experience in GPU programming.

@LapisSea insert linus torvalds fuck nvidia gif

@LapisSea well, I looked around for 2 minutes and the code seems to be open sourece, so no legal problems-yay!

@LapisSea If you actually want to do that, I would like to cooperate on implementing this for Blender. I'm sure it would be way easier with more people involved, and I also have suitable hardware to run tests.

FTC Gaming tank crews?

That's why I did all of the work or basically played slave driver to keep the group in line - only to be labeled a bad team player afterwards. Fun times.

Look at pixel shaders and how they are processed! A lot of people have trouble writing pixel shader because they think about the big picture too much. The thing is that your pixel shader will receive one "pixel" coordinate and his job is to say what to do with that pixel. So, if you want to draw a circle, you should not think about "how can I draw a circle", but, how can I know that the point is in the circle so I can color it. Then the graphic card will run multiple copies of your shader with different coordinates as input. Now, imagine you have a list of numbers you want to double. You feed your shader with a picture that is the list, the shader will run in parallel and the picture you get back is actually your list mapped with "x -> 2x". Where graphic card sucks, it when they have to iterate. The CPU is just much faster to do iterations! But with some trickery, you can transform iterative task into parallel one. One example is sum of n first integer or Fibonacci series. They both have a formula giving you the n-th ellement without iterating! Another interesting watch is raytracing shaders. 'The Art of Code" is a good channel for that: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k1vlDbhh0ws.html

Think of the graphics card as a massive mapping operation. It can map millions of inputs to millions of outputs easily. That could mean shading pixels, placing vertices, simulating water drops, or whatever. Then if you want to get *really* advanced, the GPU actually executes these mapping operations in groups, and individual threads within a group can talk to each other and coordinate. There are some really clever algorithms which take advantage of this grouping.

Sadly it wont support current realistic 3d graphics techniques as you will now need data for the inside of the object. and that will make game creation mega expensive.

@@ali32bit42 Take a look at UE's Chaos physics engine, lots of potential. And I can't wait until it's production-ready. I'll use it for sure.

@@theRPGmaster i have seen it. problem is fully destructeble environments break level design methods in most video games. and its already very expensive to model the outside of in game props now imagine having to model the inside of millions of props as well. this tech has existed since early 2000s but most devs dont use it because they cant design cool game concepts around it. why would anyone solve a puzzle when they can just break the door ?

@@ali32bit42 have one of the next major npcs say: "I heard you came in here by breaking our door. This will not work. Go find another job or I will call the police." But yeah I see what your point is. It might really take some further steps for level design to catch up with these techniques. Either with AI that supports the level design or just with new creative game concepts.

@@ali32bit42 Destruction (even if just prefabricated destruction) is always cool in action/shooter games, and really builds immersion. I bet in the next 5 years technology would progress enough so we could use voxel based physics in a whole lot more games since optimization and hardware is progressing super fast. It won't work in all games, but that's alright. We've been making story based puzzle games forever and I don't think that'll change just because of voxel based destruction (or destruction in general)

Scientists already use simulations to tackle down global issues (like weather prediction, geological simulations, etc). The only difference is that this method will be a lot faster than current implemented methods for simulations.

I dont think our processing power is that problematic. I think the problem in the real world is information. You can make a scenario on a computer but the more temperature readings we have in the real world the better we can make the simulation if you're looking at weather. Also wind samples and humidity samples would be required too etc. The problem is we cant see every single particle of air. We have samples spread out over miles between stations. If we could fill the air with sensors, we could get more and more accurate reading because we would have that information of everything going on. So unless we know all the information about a natural real world system, Our simulation's accuracy will vary. I mean theres probably inefficiencies in building simulation variables but lack of information is the issue, right?

@@DrDinkle it's not necessarily lack of information but more of how the complexity of the problem evolves for computing. If you're serious about finding the answer to your question look into asymptotic analysis (big O, big omega, and big theta). Also look into P vs NP problems. None of this has to do with fluid sim btw.

It's probably both but without the right processors, no one or only few would try to attempt and study the information required. With more powerful processors, comes more demand in powerful ways to use it.

Thanks to ryzen !

Have you heard of the "taichi elements" addon that is currently under development? I would say the "taichi" thing sounds pretty similar to this. Here is a link to a video about Taichi: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wKw8LMF3Djo.html also the github page for taichi elements addon: github.com/taichi-dev/taichi_elements

you might as well take your blender license and blend it up in a real blender

@@sharantheboss2957 haha what

That mantaflow bro...

I know - haha. And nearly 8 minutes long. FALSE ADVERTISING 😅 Still great, though.

@@jacanchaplais8083 You should ask for a refund, or pay 4 times as much. Same same.

They're scary to me.

That's the whole idea of this video unless your pc is a potato ,like me.

Depends on the gpu you have.

You are too kind. Thank you so much! 🙏

Thank you so much for your kind support Gammett!
