This package provides constrained triangulation of polygons. Ear cutting (or ear clipping) applies constrained triangulation by successively cutting triangles from a polygon defined by path/s. Holes are supported by introducing a bridge segment between polygon paths. This package wraps the header-only library earcut.hpp <https://github.com/mapbox/earcut.hpp.git> which includes a reference to the method used by Held, M. (2001) <doi:10.1007/s00453-001-0028-4>.
