Big Space

Huge worlds, high performance, no dependencies, ecosystem compatibility. Read the docs

crates.io docs.rs test suite

Highlights

  • Enough precision to render proton-sized meshes across the observable universe.
  • Uses Transform, making it compatible with most of the Bevy ecosystem.
  • No added dependencies.
  • Absolute coordinates without drift, unlike camera-relative or periodic recentering solutions.
  • Chunks the world into integer grids, from i8 up to i128.
  • Grids can be nested.
  • Spatial hashing for fast grid cell lookups and neighbor search.
  • Spatial partitioning to group sets of disconnected entities.
  • 3-5x faster than Bevy's transform propagation for wide hierarchies.
  • 👉 Extensive documentation you should read.
