Published my WebGPU Particle Life simulation online! Obviously it requires WebGPU support, and it's quite resource-demanding, so I've set the particle count to 64k for now. Also it probably doesn't work on mobile; will fix later. Enjoy: lisyarus.github.io/webgpu/parti... - ThreadSky

i think the answer is no, but is this related to the work you were doing with electrons recently, or just a fun break?

lisyarus.bsky.social•25 days ago

Completely unrelated, yep! Just having my "simulating stuff" period, lol

So cool! I'm amazed how well this runs. In awe of your coding powers.

It looks amazing!

I'm getting a black rectangle on the lower left or sometimes upper right. Is that a known thing?

lisyarus.bsky.social•24 days ago

Yay! Yep, that's a (variation of a) known bug, thanks!

Awesome! It seems every reload the colors are randomly picked? What else is random?

lisyarus.bsky.social•25 days ago

The inter-particle forces are also randomized!

pontus.granstrom.me•25 days ago

What are the rules that give rise to bigger structures? Is it purely repulsion and attraction between different kinds of particles + inertial motion?

lisyarus.bsky.social•25 days ago

It's just attraction/repulsion (and some artificial friction), the key is that forces are asymmetric (e.g. A attracts B but B repels A)

pontus.granstrom.me•25 days ago

Ah! Hence the engine-like behavior. Does that model anything that occurs in nature?

lisyarus.bsky.social•25 days ago

Yep, energy is not conserved here as well.

I've heard it's originally inspired by microbiological systems, but afaik that's about it

pontus.granstrom.me•25 days ago

It looks a bit biological, yeah. Also makes me think of the little boats you can make that propel themselves using difference in surface tension
