A 3D cellular automaton simulator that compiles to WebAssembly, written in Rust.

Right now this simulates a life-like CA (B6,8/S5,6,7,13), but I haven't yet found any CAs that demonstrate behavior as interesting as that of 2D CAs like Life (B3/S23).

To run this, run the online version, or compile it yourself:

• Install wasm-bindgen, wasm-opt, and terser.
• Run ./build-release.sh.
• Use a web server to serve the html/ directory.

To experiment with different CA rules, modify the update() method in src/ca.rs. A couple of interesting rules are: B6,7/S5,7,8 (has a diagonal spaceship, but quickly expands to fill the whole space), B6,9/S5,6,7,10 (has a similar spaceship, but it seems somewhat more rare), B5/S4,5,10 (which takes a while to settle into still lifes and oscillators).

Not yet implemented:

• Better rendering performance
• Controls to move the camera around
• Multiple cellular automata rules to choose from, without having to recompile
