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.
