Greedy triangulation

The Greedy Triangulation is a method to compute a polygon triangulation or a Point set triangulation using a greedy schema, which adds edges one by one to the solution in strict increasing order by length, with the condition that an edge cannot cut a previously inserted edge.^[1][2]

Greedy triangulation

Polygon Greedy triangulation steps. On each step a new edge (red) is added joining the nearest pair of vertex, without crossing a previously edge
