wgpu-game-of-life

A demo using the rust wgpu implementation of the WebGPU API to compute and render the Game of Life and Life-like simulations.

See the online version in a WebGPU capable browser at https://wgpu-game-of-life.fornwall.net or run a checkout locally using cargo run.

It's based on WebGPU Samples, ported to rust and wgpu (with the help of Learn Wgpu) and having some additional features for demonstration purposes. It uses winit for cross-platform windowing functionality.
