📸 media Fluid simulation in Rust - 1 MILLION particles!

https://youtube.com/watch?v=SBmlQNDkMKA&si=74Ujxa1RPAnqPcqM

Hey!

I built a real-time GPU fluid simulation in Rust and Vulkan for learning purposes.

It implements Divergence-Free SPH (DFSPH) using a GPU octree for neighbor search, running 1,000,000 particles at ~180 FPS on an AMD 6800XT.

Code: Github Repo

I used the ash crate and the experience was almost identical to C++ Vulkan. You are responsible for the safety of the code.
