Crate earclip

The earclip module is a tool to convert 2D and 3D polygons into a triangle mesh designed to be fast, efficient, and sphere capable.

Basic usage:

use earclip::earclip_float;

let polygon = vec![vec![vec![0.0, 0.0, 0.0], vec![1.0, 0.0, 0.0], vec![0.0, 1.0, 0.0]]];
let (vertices, indices) = earclip_float(&polygon, None, None);
assert_eq!(vertices, vec![0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 1.0, 0.0]);
assert_eq!(indices, vec![1, 2, 0]);
