1//! # dotloom-geometry
2//!
3//! Headless 2D geometry for Dotloom: `f64` primitives, affine transforms, exact
4//! orientation predicates, curve intersections, split/trim/extend, dimension
5//! geometry, dimensioned quantities and a bounding-box spatial index.
6//!
7//! This crate has no DOM, window or GPU dependency.

12//! let a = Curve::Line(Segment::new(Point::new(0.0, 0.0), Point::new(2.0, 2.0)));
13//! let b = Curve::Line(Segment::new(Point::new(0.0, 2.0), Point::new(2.0, 0.0)));
14//! let hits = intersect::intersect(&a, &b, ModelTolerance::DEFAULT);
15//! assert_eq!(hits.points[0].point, Point::new(1.0, 1.0));
