This is still the same kind of simulation, based on the Particle-based Viscoelastic Fluid Simulation paper. I updated it to use Wasm SIMD more fully with the help of Clang Vector Extensions, Compiler Explorer and Wasm Analyzer. Compiler explorer to play around with patterns and Wasm Analyzer to double check the final compilation.

Really awesome work. The WASM lets you show this off to a massively larger audience than a regular binary. I'd encourage you to make your Voxel project also using WASM, then you can easily turn it into a mobile/tablet game.

Thanks! I am definitely working on bringing more to the WASM world. I'd begun experimenting with 3D and multithreading and then last week decided to circle back to the 2d demo and polish it up a bit more.
