A Rust-Powered Starfield in the Browser with Macroquad + WASM

AI can get you to a working result quickly. What it doesn’t replace is the value of understanding why something looks right, breaks, or feels good to tune. I wanted a small Rust project where the mechanics stayed visible, and a browser-based starfield was a good fit: simple enough to build quickly, but visual enough to make the underlying math worth paying attention to. The nice part is that this effect is mostly a handful of small ideas wired together correctly. We are not building a full engine here. We are just using Rust, a rendering loop, and some basic projection math to create a convincing sense of forward motion. This walkthrough assumes you're comfortable reading basic Rust, but not necessarily familiar with Macroquad, WASM, or graphics code. Setting Up the Machine Before we get to the pixels, we need the right tools in the garage. For this project, we're using Macroquad's own web loader path, which keeps the setup simple: compile to wasm32-unknown-unknown, drop the output int
