PolygonConvexDecomposition_2 Concept Reference

Definition

A model of the PolygonConvexDecomposition_2 concept is capable of decomposing an input polygon \( P\) into a set of convex sub-polygons \( P_1, \ldots, P_k\), such that \( \cup_{i=1}^{k}{P_k} = P\).

Constructor & Destructor Documentation

PolygonConvexDecomposition_2::PolygonConvexDecomposition_2 ( )

default constructor.

Member Function Documentation

template<class OutputIterator >
OutputIterator PolygonConvexDecomposition_2::operator() ( const Polygon_2 P,
OutputIterator  oi 
) const

decomposes the input polygon P into convex sub-polygons, and writes them to the output iterator oi.

The value-type of the output iterator must be Polygon_2. The function returns a past-the-end iterator for the convex sub-polygons.
