Ask HN: What's the coolest computer simulation you can think of? | Apr 2023
PavelDoGreat's WebGL Fluid Simulation is the first that came to my mind. Check it out on mobile too, it's amazing.

I was interested in this too so I took a dive in.

The smoke effects are based on another project about Fluid simulation https://github.com/PavelDoGreat/WebGL-Fluid-Simulation

It also has a working demo with controls (it's collapsed by default I think, and kind of hard to see if you're not looking for it in the upper right hand corner). It's pretty astonishing how beautiful it is.

As far as I can tell, the filters and the code isn't too complicated. I am just wondering how they got those values to begin with because that's where the real magic is. There are some references there as well. One of them links to a gpu gems page that I am pretty sure I've seen before that looks really similar to this. So it's really just incremental improvements from previous works. But this version looks a lot more polished.
