Thank you for these videos! I often have the same thoughts about being/experiencing places that would be impossible to get to, and making sims to make it possible, but I’m always so unmotivated to do it. So thank you for not just exploring these questions, but for also making videos to share your work with us!

i bet this would run much better on a gpu with a cooling system and more than 10 cores (or whatever your model of macbook has)

me: 50 frames per second that’s pretty bad performance RL: *”on my MacBook Air”* thats CRAZY

this thumbnail is better

love the experimental feel to how you moved forward itteration by itteration,

rather than updating a bunch of nonadjacent cells why don't you store two buffers, and instead of changing a cell's neighbors, instead calculate how a cell is affected by its neighbors, and write that into the second buffer.

Great visualization!

Which method is cheaper to run?

11:11 that looks like the lines of a magnet.

no links to the code?

nice but I don't understand this sentence "When vector points into below right cell cell is green"

Thank you for this video

Awesome 👍

Nice

You could have used MultiGrid for the solver since it land it self to parallelism better

Can't believe I watched entire video about coding and didn't get bored

thanks for such a great explanation : ) . I 💙it

Very nice explanation. Keep it up.

No way Euler got named for a fluid dynamics problem. We're supposed to name the problem after the *second* person to solve it!

Finally good explanation

Use a mac with any non apple monitor and it destroys those bezier curves

first thing I thought about when I clicked on this video is about The Powder Toy which is a pixel based particle simulator game which actually has that exact same type of fluid simulation for simulating air in the game

thumbs up. For me, the three Lerp explanation was beautifully succint.

So persistent zero velocity is like a solid object? I wish it were easier to see it against an unmoving background .

wait you need a macbook pro to do pro stuff?? (looks sexy)

Awesome made my day :))

Finally secret revealed

loved the video! feels like discovering sebastian lagues yt channel all over again :)

Today is the first time I actually understood the bezier curve

That was one of the best explanations for advection I've seen online! Especially the pushing bubbles out of a phone screen protector analogy.

Cool

Nice 😊

What should be the grid size tho

I love this, thank you for makin my day on yt much better!

What is your programming font though? (1:23) looks cute and slick!

educational and entertaining! loved it, thank you

… and in one video he dispels a mystery. Take a bow, sir.

I loved this video! Really inspiring, and I'm sort of amazed that this was running on a macbook air too - great job :D Thanks so much for sharing.

How do you run these shader ? Can it use under sdl2?

regarding the parallel part: would it be feasible to work the opposite way? Instead of writing to 4 cells, each cell would instead read from 4 neighbors and update itself.

PerlinNoise is so simple yet so often (sadly) misrepresented. And this is a nice visualisation of it.

So far in your fluid simulations, you've pretty consistently adhered to "the incompressibility of fluids," but aren't you going to run into problems with these more advanced simulations when the true compressibility of fluids becomes non-negligible? Like, sure, water doesn't compress very much, but the gasses on Venus do.

Thanks for the beautiful video.

This is so cool, and you did a great job with the video editing! I hope you make more videos like this!

Very cool, I like the in-depth explanation. Many years ago I made a hybrid simulation that sounds a bit like your description of how the 'flip' one switches between particles and cells. My motivation was I needed the particles to interact with rigid bodies in the Box2D engine, but I didn't want to simulate collisions between particles. In every step, particles are moved and then grouped into whatever cell they land on, summing their momentum. If a cell has too much mass it expands to push the excess to its neighbors. Then each cell sums up whatever overlap it contains and makes a particle at that center of mass. Something like that... it was about 12 years ago so I forget the intricate details. Unfortunately the collision with rigid bodies proved too difficult, but it looked quite realistic just splashing around and interacting with itself. You can see an unlisted video here: XHFbTSm7qRc That was all CPU, but I always wondered how it would suit a GPU version.

Love this but if that’s how you say Euler I’ve been saying it wrong all this time 💀💀

I wish the very best on UA-cam, I am so glad I discovered your channel. Keep up the good work !

Beautiful!

do you think this could be used for electromagetics?

this is so cool, is it possible to upload the source code to a public repo?
