This is a program that simulates the growth of snow crystals. It is written in Rust and operates in a multi-threaded environment. Bevy is used for visualization.
The simulation algorithm implements the one described in reference [1]. While parameters can be dynamically changed during execution, ρ (water vapor density) is only reflected upon reset.
By toggling the comments on L.19 and L.20 in main.rs, you can switch to an implementation using the method from reference [2]. In this case, β (water vapor density) is also only reflected upon reset.
As it's built with Rust and Bevy, it should theoretically be possible to make it run in a web browser with some effort. However, since it uses rayon support for ndarray, that part would need to be modified.
cargo run --releaseYou can export STL file by pressing "Save STL" button on the control panel. The exported file will be placed in your working directory.
