Voxeltest

A simple voxel world generator, explorer and renderer written in Rust and playable on the web. Check it out at https://rustydev.codeberg.page/voxeltest/.

The creation of this project was a fun learning experience of compiling a somewhat advanced Rust application to WebAssembly and having it playable on the web. This project uses Rust for world generation and camera control, WebGL for the rendering and wasm-bindgen for the bridge between Rust and JavaScript code.

I have no intention on turning this project into anything too serious.

Building

Desktop

This is the easiest target to build. All you need is to have Rust installed and run ./scripts/build_desktop.sh followed by ./target/release/voxeltest to run it.

Web

Building for the web is more complex, requiring these dependencies to be installed:

• Rust, nightly toolchain (optional, can use stable toolchain¹ ): Run rustup toolchain install nightly.
• wasm32-unknown-unknown target: Run rustup target add wasm32-unknown-unknown.
• wasm-bindgen: Install it by running cargo install wasm-bindgen-cli.
• wasm-opt (optional¹ ): Install it from https://github.com/WebAssembly/binaryen/releases.

After installing all these dependencies, run ./scripts/build_web.sh. Then go into the web/ directory, run python -m http.server and open localhost:8000 (or use any other static web server).
