A concept that describes the set of methods that should be defined for all coordinate models used to parameterize the class Generalized_barycentric_coordinates_2
.
Creation | |
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. More... | |
Functions | |
boost::optional< OutputIterator > | weights (const Traits::Point_2 &query_point, OutputIterator &output) |
A function that computes generalized barycentric coordinates without normalization that are called generalized barycentric weights (as fast as possible algorithm is used). More... | |
boost::optional< OutputIterator > | 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. More... | |
boost::optional< OutputIterator > | coordinates_on_unbounded_side (const Traits::Point_2 &query_point, OutputIterator &output, const Type_of_algorithm type_of_algorithm) |

CGAL::Barycentric_coordinates::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
.

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.

and stored in the output iterator output
. The function returns a pointer to the last stored element.
