# Big Space Huge worlds, high performance, no dependencies, ecosystem compatibility.

## 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.](https://docs.rs/big_space) ![image](https://github.com/user-attachments/assets/cff0c58e-766c-41a0-92f7-de174807e447) ## Bevy Version Support | bevy | big_space | | ---- | --------- | | 0.15 | 0.8, 0.9 | | 0.14 | 0.7 | | 0.13 | 0.5, 0.6 | | 0.12 | 0.4 | | 0.11 | 0.3 | | 0.10 | 0.2 | | 0.9 | 0.1 | # License This project is dual licensed: * MIT License ([LICENSE-MIT](LICENSE-MIT) or [http://opensource.org/licenses/MIT](http://opensource.org/licenses/MIT)) * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or [http://www.apache.org/licenses/LICENSE-2.0](http://www.apache.org/licenses/LICENSE-2.0)) ## Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
