2D Predictive-Corrective Smoothed Particle Hydrodynamics (SPH) implementation in Rust with WASM + WebGL

Reimplementation of my previous Rust PCISPH repository now including a WASM thread parallel solver using rayon-bindgen-wasm

For further information, see SPH tutorials on my website, including an introduction to SPH math and a simple SPH solver.

Since Github Pages does not support setting HTTP headers, this project is deployed on Netlify after building with Github Actions.

Link to demo

Install dependencies

npm install
rustup install nightly

Compile WASM, run webpack, and spawn a local server (note you might need to download additional rust-src, etc. with rustup)

npm run serve

Then visit http://localhost:8080

This solver is not exactly PCISPH, but can be viewed as 1-iteration of SPH relaxation plus sub-stepping. The “prediction-relaxation” scheme of my implementation actually comes mainly from the (much easier to follow) paper "Particle-based Viscoelastic Fluid Simulation”, as opposed to "Predictive-Corrective Incompressible SPH”.
