# axiolid-spatial
Deterministic, callback-based spatial acceleration: a median-split BVH over bounded objects and a uniform grid for point KNN and radius search, both behind the `SpatialIndex` query contract. They return candidates only, never exact intersections. It also provides barycentric and mean-value coordinates for interpolating values given at triangle, tetrahedron and polygon corners.
```bash
cargo add axiolid-spatial
