#include <CGAL/Triangular_field_2.h>

Definition

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_2has to be instantiated by a model of the concept StreamLinesTraits_2.
Is Model Of:
VectorField_2
