Triggered by yesterday's discussion about old fluid sims, a short thread with some more examples from that period 2007-2009 to explore fluid dynamics for marbling...

So, I finished making my fluid sim gift on ESP32!

Please excuse my nails, I was literally working with bitumen and managed to clean it off my hands, but it started to hurt scrubbing

Over the past two months I've been actively revisiting, updating/extending and now close to finishing this 1.5 year long journey... The actual journey has been much longer, been toying with (faux) fluid sims since ~2007...

A 50 second preview of one of my fave variations, best enjoyed fullscreen... Tried to achieve some molten, dichroic/irridescent glass & oilfilm aesthetics here, but there're over a dozen of other very different routes/styles possible too, with 25+ parameters to tweak the simulation and look & feel...

Made with https://thi.ng/shader-ast & https://thi.ng/shader-ast-stdlib

* Basic support for #Jax is part of #Transonic with v0.7.x

* #FluidImage v0.5.x has a number of improvements, such as work towards matching #UVmat (the MATLAB #PIV suite), new executors and a command `fluidimage-mean`

A little video preview of a section of the upcoming new thi.ng website:

(edit: moved from YT to makertube)

It's so nice for me to see these 10 computational art pieces & experiments all in one place (and most of them interactive & randomizable), also in the knowledge that apart from using @vite for bundling, everything else is entirely made using https://thi.ng/umbrella packages and tooling (three of the pieces are also partially written in #Ziglang / #WASM). Unlike the video (which at 1080p is ~110MB), on the website these ten realtime evolving animations together are only a ~650KB download (i.e. ~0.55% filesize) and all of them are running fluidly even on my old iPhone 11! Thanks to using `IntersectionObserver`, only a single piece is active at any one time...

Another side effect from this exercise: All these projects are only a small selection from the past 3 years, but most of them haven't been updated in the last 1-2 years. There were breaking changes (esp. the Zig parts, which I still have to largely address), but most of the supposedly breaking changes in #ThingUmbrella packages were actually super easy to address. I'm only mentioning this, since it's great to sometimes be completely in a "normal" user's shoes and see how painful (or not!) some of these changes are/can be... I'm often losing a lot of time contemplating making wide-ranging (but IMHO better & needed) changes, but always also trying to consider the effects of those on other people... This anti-bitrot exercise absolutely helped me to vindicate this approach!
