"Dear fellow scholars..."
Yep, I'm most definitely a scholar. I spend most of my days scholaring with other scholars at the local scholartorium. I was just saying to my friend earlier today (also a scholar), wouldn't it be great if everyone were scholars? Anyway, great vid. Scholar out!

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.

@@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.

Me too, imagine this in Houdini 🥺
Blender has updated to use particle based fluids but I'm not sure if that means the sim calculates on your GPU like this video talked about. You still need to establish a domain, but it can be "adaptive" and grow or shrink based on what the fluid does.
Me too. I've been waiting for a good opensource fluid simulator that I can use for my micro-hydroelectric projects.
@@recklessroges Would love to see this applied to aerodynamics. Wonder if it can be used in a dynamic system, like simulating airflow over a moving propeller and aircraft. Being able to visualize the nuances of the air flow and try different configurations for an aircraft quickly would be great.
@@hashemieada4846 there are new sparse solvers in H18.. still no support for sparse gpu sim, tho.. i think they have to redo microsolvers for that to happen..

That's a fantastic philosophy, and it really shines through in the quality of the work you produce and the clear passion you express for this quite niche field. I don't do CGI or complex maths, but there's something addictive about watching you do what you love.

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

Please, please keep doing these videos. I love it whenever I see a new Two Minute Papers video in my sub box. I'm by no means a materials engineer or computer scientist, so your excellent, concise explanations of these topics makes it possible for hobbyist-level computer enthusiasts like me to stay up to date with cutting-edge physics simulation. Thank you for your work!
I love your videos! Been watching for quite a while now. I love how short and to the point the videos are, they make it much easier to digest the complex information being discussed. Keep up the great work!
I absolutely love these videos! You're clearly genuinely excited by the progress made in the fluid simulation field, and it's a subject I'm really interested in too. Your explanation of the drawbacks of computational parallelism was intuitive and accessible. Keep doing what you're doing! You've got 1m in your channel's future
I've been enjoying watching your older videos from time to time, now that you reminded me about them I'm going to do it more :) Thanks for keeping this up through the years, you deserve the popularity!
We love your videos a lot. I click it as soon as possible. It is really a treat to know new technologies about simulations and Ai

Love to see all the different kinds of things you post. For me the excitement comes from how it inspires my imagination for what I may be able to see done in real time just a few years down the road in the many video games I play. Keep up the great work!
Love watching fluid simulations. Thanks for doing the work to get these videos up. It IS appreciated.
I've never understood how the graphics card was able to perform different types of tasks faster than a cpu. I finally get it now thanks!
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: ruclips.net/video/k1vlDbhh0ws/видео.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.
1:37 imagine if there was realstic flowing water in minecraft... that would be so weird.

Woooooow! I'm facing that problem exactly right now: I'm working on a simulation of an aircraft splashing down into water, and given the speed of the aircraft and the splash in all directions, the domain is huuuuge. At any vaguely reasonable resolution that means 32 GB of RAM fill up long before the first frame is calculated, the software freezes and no patience in the world will let the simulation finish... so this is gold!!
We should be the ones thanking you! Thank you for exposing these game-changer innovations for us in an accessible and fun manner! I'm so excited for the future of fluid sim, and I'm so grateful for people like you, who are contributing to the spread of this information and helping move the tech industry foward!
I love your videos man, I hope you continue to do more. This stuff is mindblowing to me
Soon enough, we'll have processors fast enough to simulate the real world to tackle down different types of global issues. What a time to be alive indeed to witness such amazing physics!
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 !
every time i hear the word real time i think of Dennis Gustafsson who’s making a voxel based destruction game. it’d be really cool to see more games that utilize voxel based physics
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)
Appreciate the effort and time taken man, thank you!
Thank you for these wonderful videos!

'You fellow scholars, have started to love the fluids'
hmm...
Holy crap, imagine Splatoon using this.
Splatoon's 'simulation' is already 100x faster than this, and has little need for this level of accuracy. At seconds per frame, this is not a realtime technique.
Games like Splatoon or the goo from Portal 2 opt for a 'good enough' technique that is blazing fast, but only kindof sortof accurate.
This is mainly a technique for rendering accurate, large-scale simulations in days instead of months.
That said, games with this level of detail would be amazing! I believe that pseudo-accurate realtime (
@@sentinelnox6894 I was talking about new game mechanics - paint spilling from pools, containers, or high-viscosity paint slowly flowing like honey. It's slower for sure, but that's what optimization and hardware is for. It would absolutely add a lot to the gameplay.

@@auxencefromont1989 to say it will have no impact is a little harsh, being able to simulate fluid faster means you can change variables and re-render more so while i dont know much about biology personally, being able to run more varied simulations has to be beneficial, also anything that improves gaming improves training for example as vr improves we might get to the point where surgeons are able to simulate a surgery and run through it 100s of times in a day before performing that surgery, im sure you can see how that could be beneficial
