Overview

About
Maintained by Michael SumnerFirst published 2018-03-134 releasesCRAN page ↗GitHub ↗

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 which includes a reference to the method used by Held, M. (2001) doi:10.1007/s00453-001-0028-4.
