Deployed a new real-time fluid simulation - "waterball"! Interact with the water on a sphere🌏. demo : waterball.netlify.app repo : github.com/matsuoka-601/w… The demo runs smoothly even on my 6-year-old iPad! (see the reply)

Hey, don't "optimize" conditional moves with mix()+step(). Please stop advising that. Why: iquilezles.org/articles/gpuco…

Related to this I have also tried to "vectorize" operations, like packing as many components as possible to a single vec4 expecting performance improvement, but **nothing improved**. That wasn't how vectorization on GPU works. Just floats are as good as vec4s.

AHC043（日本橋ハーフマラソン2025冬）で優勝したので解法の解説記事をブログに書きました！ heuristic contest とても面白いのでもっと人増えてほしい 🏃

Been recently looking into fluid simulations again. This time I've testing if I can make a good SPH simulation but only having "average" cell particles. It seems to work surprisingly well, and it doesn't need sorting either. compute.toys/view/1782 Explanation thread👇🧵

X's notification tab is unreliable 😡　apparently it misses many mentions. feel free to resend if I missed anything important while I'm inactive

I've implemented a Gaussian Splatting renderer in VRChat! It was tricky, but turned out to be feasible. I've also made a public gallery with 12 splats you can check out: vrchat.com/home/launch?wo… By the way the renderer is open source! github.com/MichaelMoroz/V…

昨日のブログでもちょっと触れたんですが、明日朝から AWTF の Heuristic 部門に出てきます！　AI に負けないようにがんばります I'll be in the Heuristic part of AWTF tomorrow! will try hard not to let OpenAI's AI beat me

we're competing in the AtCoder World Finals programming contest. real nailbiter — OpenAI has been #1 for most of the contest. looked like it might be over when Psyho pulled ahead, but we've just retaken the lead. 1 hour and 20 minutes to go!

Humanity has prevailed (for now!) I'm completely exhausted. I figured, I had 10h of sleep in the last 3 days and I'm barely alive. I'll post more about the contest when I get some rest. (To be clear, those are provisional results, but my lead should be big enough)

Psyho 先生ありがとう……😭

saharan took 4th place in World Tour Finals 2025 Heuristic! #AtCoder #WorldTourFinals2025Heuristic atcoder.jp/users/saharan/… got shaken up to the 4th place! it was close the prize 😣 next year maybe
