    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!

      @Esteban Singh 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.

      I'm working on a minecraft fluid simulator. The result is blocky but it's a lot of fun to make because it's simplified. I've managed to add static pressure, momentum and a few other things.
      It uses the CPU cores still haven't tried GPU yet.

    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!

    • Christian Baune
      Christian Baune 2 years ago +13

      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: thexvid.com/video/k1vlDbhh0ws/video.html

    "If no one watches them, so be it; I still love doing this".
    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.
    Also the simulations are pretty.

    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!

    • Zaire

      These improvements are only cost-wise. You don't need as powerful, and therefore not as expensive, of a computer to run them.
      If you're a government or large organisation trying to simulate problems, you can afford a super-computer.

    • Britta Hüter
      Britta Hüter 2 years ago +2

      The problem now is not the science or the speed of it but the idiots running our governments that don't believe in science or just attack it to promote their grab for more money or power. Attacking science is the way to go, merchants of doubt.

    • MarsCorporations
      MarsCorporations 2 years ago +1

      Every simulation (weather, infected people, water, everything) trades off accuracy vs speed. You use a simplified model of reality, simulate that, tweak it until it represents reality good enough for your usecase. Better and faster and bigger computers will only increase the accuracy of computations, not the "scale" of what is simulatable and what is not. We can already simulate the whole universe with very low accuracy and a single electron orbiting a proton with very high accuracy.

      ​@Gewel ✔ Well I bothered to look it up and apparently, it's possible to buy stock in private companies but that comes with a boatload of caveats. The short of it is not just anyone can own stock in Valve but it is technically possible. That's about as far down that rabbit hole as I feel like going but thanks, I learned something today.

    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!!

      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.

    I really love your videos, super interesting. Only thing I would add is on what gpu the simulations in the video were computed on. And second thing, this is amazing, but the real question is when will a fast tool like this be inside cinema, max, blender, maya, Houdini and so on... this is what matters at the end

      I guess we need a couple more decades for that, maybe future computers will have dedicated "physics cards" as well as GPUs.

      @Animation Space Sounds like you can flood a valley with a single water bucket placed at build limit. Doubt that'll be a good addition to Minecraft

      @DANDAN THE DANDAN How about this: A grid voxel particle system for the simulation? This allows for source blocks that spawn the fluid but the rest of the fluid is realistic.

      It's a cool idea, but it would drastically change how the game is played, and how water is treated. How would a single block of water behave on a flat plate. How far out does it spread? How thin does it get? How do you pick it up?
      It could be done, but it would be an enormous change that might not entirely fit the game. It would probably go about as good as the no cubes mod...

    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

    • Nahome Tesfay

      @Ali 32bit Why do you assume that in a game where everything can be destroyed everything must be destroyed? In my previous comment, I mentioned how destruction can be a tool the player has to use carefully. On the other hand, perhaps destruction is the goal, but it's difficult to destroy things. In my previous comment, I also mentioned that a game where you can destroy everything is probably not worth the effort and could likely be made more easily with some indestructible objects Once again I agree that a game where you can destroy everything is likely not worth making. Where we disagree is I think destruction can be an interesting mechanic. I've definitely seen this mechanic used to great effect in flash games and can imagine it's use in more complicated games.

    • Ali 32bit
      Ali 32bit Year ago

      @Nahome Tesfay i think you missed something. there is not much that can be done with level design if players can literally smash everything. take any game right now without destruction. can you imagine if they had unliminted destruction ? it would be impossible to tell stories or have scripted events or puzzles . teardown itself has a wall that prevents players from leaving the map and it has no story . face it fully destructble levels are just too much work that the game does not even need . now we have to worry about inside of buildings . under ground . inside props and so much more stuff that has nothing to do with gameplay. its just too expensive and no game dev will want to do it. edstructble games have been around since ps2 era. devs just dont want to use them . devs already have destruction as a game mechanic But it is intentional and designed to lead players . so no . devs dont want it or like it its extra work that their game does not need.

    • Nahome Tesfay
      Nahome Tesfay Year ago

      @Ali 32bit I think you're selling the mechanic short. To stick with your escape example, if you try to smash your way through a level that could destroy the entire level and crush your character, so you have to be careful about what you break and what you leave intact. Destruction can be a creative process like machining or sculpting tools. Destruction can also transform level for example using an excavator. I think most destruction based mechanics don't need to simulate destruction realistically, so I'm not sure if voxles are worth it, but destruction as a game mechanic is a cool idea.

      @Ali 32bit I did not say anything about story missions, or so i thought. i meant in action/fps games that don't really need a solid story. It could be like a rouguelike and such

    • Ali 32bit
      Ali 32bit 2 years ago

      @Skwishy Dude you cant randomly generate story levels. they have to be hand made. most of the time. as i said we already have the tech but nobody is using it .

    What program are these simulations being rendered in? I love seeing these videos and I want to play around with fluid sims but I feel like something like Blender probably isn't equipped with cutting edge simulation solutions from like, a 2020 paper

  • Philtography - Cotswold Wedding Photographer

    A really cool video today, one suggestion that I think would be super helpful and informative would be a 'time counter' overlayed on each video so it's easier to get an understanding of how long these simulations take to render.
    Also, is there a 'standard machine' that you are referring to for how long these renders take? For example when it says 200ms/frame surely that will change hugely depending on the CPU (or GPU), so an overclocked 64 core Threadripper compared to my old Quad-Core won't both take 200ms per frame.
    I also wonder if any of these new GPU accelerated simulations are using the Tensor Cores on Nvidia's cards which sound like they would be perfect for this stuff or if it just uses the general shaders?
