README

Big Space

partitioning screenshot

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

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.
