CGAL::Greene_convex_decomposition_2< Kernel, Container > Class Template Reference

#include <CGAL/Polygon_convex_decomposition_2.h>

Definition

The Greene_convex_decomposition_2 class implements the approximation algorithm of Greene for the decomposition of an input polygon into convex sub-polygons [6].

This algorithm takes \( O(n \log n)\) time and \( O(n)\) space, where \( n\) is the size of the input polygon, and outputs a decomposition whose size is guaranteed to be no more than four times the size of the optimal decomposition.

Template Parameters

Kernel	must be a geometric kernel that can be used for the polygon.
Container	must be a container that can be used for the polygon. It is by default std::vector<typename Kernel::Point_2>.

Is Model Of:
