+[![codecov](https://codecov.io/gh/MIERUNE/earcut-py/graph/badge.svg?token=XdDPzdkBo4)](https://codecov.io/gh/MIERUNE/earcut-py)
+
+A pure Python port of the [mapbox/earcut](https://github.com/mapbox/earcut) polygon triangulation library.
+
+- Based off of the earcut 2.2.4 release.
+- A small utility `earcut.utils_3d` can be used to project polygons from 3D to 2D space before triangulation, instead of just ignoring z components. (requires NumPy)
