When 32-bit worlds aren't big enough
- Rust 100%
| Filename | Latest commit message | Latest commit date |

06c66a77f0- Introduced a new `require_visibility` flag to control whether only visible entities are considered when performing the nearest-object search. - Added corresponding accessor and configuration methods, with a default value of `true`. - Updated nearest-object search logic to respect the new flag in brute force and grid-based methods. |

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
i8up toi128. - 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.
