CGAL 5.6  3D Mesh Generation

#include <CGAL/Sizing_field_with_aabb_tree.h>
The class Sizing_field_with_aabb_tree
is a model of concept MeshDomainField_3
.
It provides a sizing field to be used in the meshing process of a polyhedral surface with features.
At each query point p
, the field value is the minimum of the distances to
p
does not belong to, andC
it does belong to, the intersection points of C
with the plane orthogonal to C
and passing through p
.This sizing field is designed to be used for the edges of the mesh complex, in Mesh_edge_criteria_3
or as edge_size
in Mesh_criteria_3
. Using this sizing field for complex edges provides a highquality hint to the protecting balls placement algorithm, since it ensures that no protecting ball will intersect a surface patch to which the corresponding vertex does not belong.
GeomTraits  is the geometric traits class. It must match the type Triangulation::Geom_traits , where Triangulation is the nested type of the model of MeshComplex_3InTriangulation_3 used in the meshing process. 
MeshDomain  is the type of the domain. It must be a model of MeshDomainWithFeatures_3 , and derive from CGAL::Polyhedral_mesh_domain_with_features_3

Creation  
Sizing_field_with_aabb_tree (const FT &d, const MeshDomain &domain)  
Constructor for the sizing field. More...  
Operations  
double  operator() (const Point_3 &p, const int dim, const Index &id) const 
returns the value of the sizing field at the point p , assumed to be included in the input complex feature with dimension dimension and mesh subcomplex index id .  
CGAL::Sizing_field_with_aabb_tree< GeomTraits, MeshDomain >::Sizing_field_with_aabb_tree  (  const FT &  d, 
const MeshDomain &  domain  
) 
Constructor for the sizing field.
d  the maximal value returned by operator() , corresponding to an upper bound on feature edge lengths in the output mesh. 
domain  the mesh domain to be meshed
