use delaunator::{Point, triangulate};

let points = vec![
    Point { x: 0., y: 0. },
    Point { x: 1., y: 0. },
    Point { x: 1., y: 1. },
    Point { x: 0., y: 1. },
];

let result = triangulate(&points).expect("No triangulation exists.");

println!("{:?}", result.triangles); // [0, 2, 1, 0, 3, 2]
