A simple Minecraft written in Rust with the Piston game engine
Hematite is a partial Minecraft world viewer written in Rust using the Piston game engine. It reads existing Minecraft 1.8.8 save files and renders them — it is not a playable game despite what the description implies. Useful mainly as a Rust graphics/game-engine learning project or a reference for parsing Minecraft's binary formats.
The NBT and region file parsers are solid reference implementations for anyone needing to read Minecraft's binary formats in Rust. Block state and model parsing from actual Minecraft data shows real-world use of serde-style deserialization against a complex, underdocumented format. The Piston integration is a practical example of wiring a mid-complexity 3D renderer without a full engine. It still compiles and received commits in 2026, which is more than most abandoned game experiments can say.
This is a world viewer, not a game — the repo name and description actively mislead. There is no gameplay, no server, no entities, no physics. The codebase is tiny (a handful of source files) and has not grown meaningfully in years, so it cannot serve as a reference for anything beyond basic chunk rendering. Piston itself is a niche and stagnant engine choice that limits the audience. The Java tool in src/tools/ sitting alongside Rust source is a small but telling sign of an unfinished, loosely organized project.
