PolygonWithHolesConvexDecomposition_2 Concept Reference

Definition

A model of the PolygonWithHolesConvexDecomposition_2 concept is capable of decomposing an input polygon \( P\), which may have holes, into a set of convex sub-polygons \( P_1, \ldots, P_k\), such that \( \cup_{i=1}^{k}{P_k} = P\).

template<class OutputIterator >

OutputIterator PolygonWithHolesConvexDecomposition_2::operator()	(	const Polygon_with_holes_2 &	P,
		OutputIterator	oi
	)		const

decomposes the input polygon with holes 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.
