Sure! All you need is a way to display a buffer of pixels on the screen. No other communication with the video card required, it's all CPU until the frame is ready. Incidentally, I have an ongoing hobby project that does just that: a pure software platform-agnostic 3D renderer with zero non-optional dependencies written in Rust. It comes with a few example programs that use SDL2 and ncurses(!) to handle display and events. I'm planning to add a Wasm example at some point as well. The project is heavily work-in-progress, and definitely not yet optimized nearly to Quake levels, but on the other hand the code should be relatively clean and useful for learning purposes. https://github.com/jdahlstrom/retrofire https://github.com/jdahlstrom/retrofire
