u-geometry 0.4.0

//! Domain-agnostic computational geometry library.
//!
//! Provides fundamental geometric primitives (2D and 3D), transformations,
//! polygon operations, collision detection, and spatial indexing.
//!
//! # Modules
//!
//! - **`primitives`**: Core types — `Point2`, `Vector2`, `Segment2`, `AABB2`,
//!   `Point3`, `Vector3`, `AABB3`
//! - **`polygon`**: Polygon operations — area, centroid, convex hull, winding
//! - **`transform`**: Rigid transformations — `Transform2D`, `Transform3D`
//! - **`robust`**: Numerically robust geometric predicates (Shewchuk)
//! - **`collision`**: collision detection — SAT for convex polygons, exact
//!   overlap for concave simple polygons (`polygons_intersect`), AABB overlap
//!   (2D and 3D)
//! - **`minkowski`**: Minkowski sum and NFP for convex polygons
//! - **`spatial_index`**: Linear-scan spatial indices for 2D and 3D AABB queries
//!
//! # Architecture
//!
//! This crate is a general-purpose geometry layer: it contains no
//! domain-specific concepts — nesting, packing, scheduling and the like are
//! defined by whatever consumes it.
//!
