# Game of Life [](https://github.com/lloydmeta/gol-rs/actions/workflows/ci.yml)
Conway's Game of Life implemented in Rust and OpenGL via [`gfx-rs`](https://github.com/gfx-rs).
Done as an exercise to practise Rust and get my feet with with OpenGL.
Areas explored:
* General rendering
* Vertex, fragment shaders
* [Pipeline state objects](https://gfx-rs.github.io/2016/01/22/pso.html)
* [Rayon](https://github.com/nikomatsakis/rayon) for parallel processing
* Building and deploying cross-platform binaries via GH Actions
## Usage
You can run the executable by downloading one of the binaries in [releases](https://github.com/lloydmeta/gol-rs/releases), or
via `cargo install gol`, then running `gol`, or if you've cloned the repo,`cargo run`.
```bash
OPTIONS:
-h, --grid-height <grid-height> Height of the grid [default: 80]
-w, --grid-width <grid-width> Width of the grid [default: 100]
-u, --update-rate <update-rate> Number of updates to the game board per second [default: 30]
--window-height <window-height> Height of the window [default: 768]
--window-width <window-width> Width of the window [default: 1024]
```
If running via `cargo`, options need to be passed by appending `--`, i.e. `cargo run -- -h 10 -w 10`.
## Todo
* Optimise!
