Problem Definition
Definition 1
A simple polygon is a polygon whose interior is simply connected, i.e., it consists of a single connected component and does not contain holes.
Definition 2
A triangulation of a simple polygon P with N vertices is a partition of the polygon, considered as a full-dimensional subset of the plane, into N − 2 nonoverlapping triangles such that the set of vertices of these triangles is the set of vertices of P, such that no edge of a triangle lies outside of P, and such that no triangle edges intersect except in their common endpoints.
Key Results
In addition to the regularization-based approach by Garey et al. [7], three other \(\mathcal{O}(N\log N)\)-time algorithms are milestones on the way toward an optimal linear-time algorithm. In the first of these algorithms [2], Chazelle uses a linear-time “polygon-cutting” approach to partition a simple polygon by a suitably chosen diagonal; the resulting...
