Constructor & Destructor Documentation

◆ BarycentricCoordinates_2()

BarycentricCoordinates_2::BarycentricCoordinates_2	(	const std::vector< Traits::Point_2 > &	vertices,
		const Traits &	barycentric_traits
	)

Creates a class that implements generalized barycentric coordinates for any query point that does not belong to the polygon's boundary.

The polygon is given by a range of vertices of the type Traits::Point_2 stored in a container of the type std::vector.

◆ coordinates_on_bounded_side()

boost::optional<OutputIterator> BarycentricCoordinates_2::coordinates_on_bounded_side	(	const Traits::Point_2 &	query_point,
		OutputIterator &	output,
		const Type_of_algorithm	type_of_algorithm
	)

A function that computes generalized barycentric coordinates on the bounded side of a polygon with one of two possible algorithms: one is precise and one is fast.

The algorithm type is specified by the parameter type_of_algorithm. Coordinates are computed with respect to a query point of the type Traits::Point_2 and stored in the output iterator output. The function returns a pointer to the last stored element.

◆ coordinates_on_unbounded_side()

boost::optional<OutputIterator> BarycentricCoordinates_2::coordinates_on_unbounded_side	(	const Traits::Point_2 &	query_point,
		OutputIterator &	output,
		const Type_of_algorithm	type_of_algorithm
	)

A function that computes generalized barycentric coordinates on the unbounded side of a polygon with one of two possible algorithms: one is precise and one is fast.

The algorithm type is specified by the parameter type_of_algorithm. Coordinates are computed with respect to a query point of the type Traits::Point_2 and stored in the output iterator output. The function returns a pointer to the last stored element.

◆ weights()

boost::optional<OutputIterator> BarycentricCoordinates_2::weights	(	const Traits::Point_2 &	query_point,
		OutputIterator &	output
	)

A function that computes generalized barycentric coordinates without normalization that are called generalized baycentric weights (as fast as possible algorithm is used).

Weights are computed with respect to a query point of the type Traits::Point_2 and stored in the output iterator output. The function returns a pointer to the last stored element.
