Implementation of Boids
Boids is an example of emergent behavior; that is, the complexity of Boids arises from the interaction of individual agents (the boids, in this case) adhering to a set of simple rules. The rules applied in the simplest Boids world are as follows:
- separation: steer to avoid crowding local flockmates
- alignment: steer towards the average heading of local flockmates
- cohesion: steer to move towards the average position (center of mass) of local flockmates
JS version
Uses basic web worker for computation, w/ OffscreenCanvas to draw on the canvas off of the main thread.
Requires no transpilation and can be served directly. Entry point (to be set in index.html) is /js/script.js
Rust version
Uses Web Assembly for computation, written in Rust. Also uses a Broadcast Channel for basic interop between JS worker and WASM thread. And imports the web-sys crate to call canvas methods efficiently.
Needs to be compiled
wasm-pack build --target web
Entry point (to be set in index.html) is /js/wasm.js
