# Big Space



Huge worlds, high performance, no dependencies, ecosystem compatibility. [Read the docs](https://docs.rs/big_space)

[![crates.io](https://img.shields.io/crates/v/big_space)](https://crates.io/crates/big_space)

[![docs.rs](https://docs.rs/big_space/badge.svg)](https://docs.rs/big_space)

[![test suite](https://github.com/aevyrie/big_space/actions/workflows/rust.yml/badge.svg)](https://github.com/aevyrie/big_space/actions/workflows/rust.yml)



## 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 nestable integer grids, from `i8` up to `i128`.

- Spatial hashing for fast grid cell lookups and neighbor search.

- Spatial partitioning to group sets of connected cells.

- Great performance scaling and parallelism with massive entity counts.

- 👉 [Extensive documentation you should read.](https://docs.rs/big_space)
