Implementation of Ryo Kobayashi's dendritic crystal growth algorithm from the paper Modeling and numerical simulations of dendritic crystal growth.

The simulation part is written in Rust that is compiled into webassembly. Visualization and interaction is implemented in TypeScript.

npx webpack build --mode production

Tests

Currently, only the functions of the wasm module are tested.

cargo test
