CGAL::Construct_initial_points_labeled_image< C3t3, MeshDomain > Struct Template Reference

#include <CGAL/Mesh_3/Construct_initial_points_labeled_image.h>

Definition

template<typename C3t3, typename MeshDomain>
struct CGAL::Construct_initial_points_labeled_image< C3t3, MeshDomain >

Functor for generating initial points in labeled images.

This functor is a model of the InitialPointsGenerator_3 concept, and can be passed as a parameter to CGAL::make_mesh_3 using the CGAL::parameters::initial_points_generator() parameter function.

This functor scans the complete image to detect all its connected components, and constructs points on the surface of each of them. Its goal is to initialize each component, each of them corresponding to a subdomain. It ensures that each component will be initialized, i.e. represented by at least one cell of the triangulation.

Template Parameters

C3t3	model of MeshComplex_3InTriangulation_3
MeshDomain	model of MeshDomain_3

Is model of

InitialPointsGenerator_3
