To give a bit more detail on the SPH implementation, I build a tiled hash grid, where the hash points to a 4x4x4 tile (+ some linear probing for conflict handling).

Re-wrote my acceleration structure for neighbourhood search based on some insight from @vassvik.bsky.social and got significant speedups on large fluid simulations:) Here’s ~1/2 million particles ✨
