CGAL::Triangular_field_2< StreamLinesTraits_2 > Class Template Reference

#include <CGAL/Triangular_field_2.h>

Definition

template<typename StreamLinesTraits_2>
class CGAL::Triangular_field_2< StreamLinesTraits_2 >

This class provides a vector field specified by a set of sample points defined on a triangulated domain.

All sample points are inserted to a Delaunay triangulation, and for each point p in the domain located in a face f, its vector value is interpolated from the vertices of the face f.

Template Parameters

StreamLinesTraits_2

has to be instantiated by a model of the concept StreamLinesTraits_2.

Is model of

VectorField_2

Types
typedef StreamLinesTraits_2::FT	FT
	the scalar type.
typedef StreamLinesTraits_2::Point_2	Point_2
	the point type.
typedef StreamLinesTraits_2::Vector_2	Vector_2
	the vector type.

Creation
mplate< class PointIterator1, class VectorInputIterator >	Triangular_field_2 (PointInputIterator first_point, PointInputIterator last_point, VectorInputIterator first_vector)
	Defines the points in the range [first_point, last_point) as the sample points of the triangular field, with the corresponding number of vectors started at first_vector.
