Rust4D #

A 4D game engine in Rust: renders 3D cross-sections of 4D geometry via a GPU compute pipeline, with 4D physics, Lua scripting, spatial audio, and an egui HUD. Cargo workspace: app crate in src/, engine crates in crates/rust4d_*.

Requirements #

  • Build and test inside the nix dev shell: nix develop --command cargo test --workspace
  • Keep cargo clippy --workspace --all-targets warning-free
  • Before changing camera, movement, physics, or slicing code, load the slice-invariant skill; for math/shader conventions, load 4d-conventions
  • tests/slice_invariant.rs must pass — it guards the engine's core invariant
