#include <CGAL/Triangular_field_2.h>
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.
| StreamLinesTraits_2 | has to be instantiated by a model of the concept StreamLinesTraits_2. |
VectorField_2 Regular_grid_2<StreamLinesTraits_2> Types | |

| 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. | |
