## 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)
