I really wish these were 3D simulations. The 2D ones are always a bit off to me...

Incredible stuff.

That link just goes to the libgenis home page (although cool site! will have a look around).

All I could find from the OP so far is: https://www.reddit.com/r/VoxelGameDev/comments/ecxiyw/voxels... that has a few links to a YT demo and some papers referenced.

It also takes into account surface tension. Bubbles of denser/lighter materials cling to the interfaces, rather than sinking or rising.

When you set all materials to the same density, you get a cold surface, with hot matter below it.

Earlier quoted context omitted.

I'm surprised the simulation is run on the CPU! This problem has solutions that fit the GPU well, even for grid particle conversions.

this kind of sims are better suited for CPU ;-), gpu are good to work on meshes, not really on pure particles. At GPU are super good for grid based hydro.

"gpu are good to work on meshes, not really on pure particles"

Why?

Having thousands of particles, all in need of doing the same operations on them in parallel screams GPU to me. It is just way harder to program a GPU, vs a CPU.

Would be fun to add an emulsifier :) (particles that bond with 2 colors)
