Ideal gas simulation

A webpage that simulates how gas behaves using bouncing balls. The intention is for education purposes, to provide a visual aid when explaining things like:

• What heat is
• How heat effects changes in states of matter
• How water reaches an equilibrium state where its exchange between water vapor is continuous but unseen
• How adding ice to water causes the ice to melt while cooling down the water
• Similarly, how a spot of heat propogates through a medium

Building

The simulation is written in Rust targeting WebAssembly (wasm) using wasm-pack. To build, run:

wasm-pack build -d html/js --target=web

Viewing it on a local machine requires a webserver to serve the javascript module required to load wasm. The serve.sh script uses the built-in webserver in python3 for this. You can start it by running:

python3 -m http.server 8080

Then you can open the page at http://localhost:8080/html/ in your web browser.
