## Definition

template<typename Tr>
class CGAL::Mesh_facet_criteria_3< Tr >

The class `Mesh_facet_criteria_3` is a model of `MeshFacetCriteria_3`.

It provides a uniform bound for the shape criterion, a uniform or variable sizing field for the size criterion and/or a uniform or variable distance field for the approximation error criterion.

Template Parameters

  Tr | must be identical to the nested type `Triangulation` of the instance used as model of `MeshComplex_3InTriangulation_3`.

Is Model Of:
  `MeshFacetCriteria_3`

## Constructor & Destructor Documentation

## ◆ Mesh_facet_criteria_3() [1/2]

template<typename Tr >

CGAL::Mesh_facet_criteria_3< Tr >::Mesh_facet_criteria_3 | ( | const FT & | angle_bound,
|  | const FT & | radius_bound,
|  | const FT & | distance_bound,
|  | Mesh_facet_topology | topology = `FACET_VERTICES_ON_SURFACE`,
|  | const FT & | min_radius_bound = `0.`
| ) |  |

Returns an object to serve as criteria for facets.

Parameters

  angle_bound | is the lower bound for the angle in degrees of the surface mesh facets.
  radius_bound | is a uniform upper bound for the radius of the surface Delaunay balls.
  distance_bound | is an upper bound for the center-center distances of the surface mesh facets.
  topology | is the set of topological constraints which have to be verified by each surface facet. See section Delaunay Refinement for further details. Note that if one parameter is set to 0, then its corresponding criteria is ignored.
  min_radius_bound | is a uniform lower bound for the radius of the surface Delaunay balls. Only facets with a radius larger than that bound will be refined.

## ◆ Mesh_facet_criteria_3() [2/2]

template<typename Tr >
template<class SizingField , class DistanceField >

CGAL::Mesh_facet_criteria_3< Tr >::Mesh_facet_criteria_3 | ( | const FT & | angle_bound,
|  | const SizingField & | radius_bound,
|  | const DistanceField & | distance_bound,
|  | Mesh_facet_topology | topology = `FACET_VERTICES_ON_SURFACE`,
|  | const FT & | min_radius_bound = `0.`
| ) |  |

Returns an object to serve as criteria for facets.

The types `SizingField` and `DistanceField` must be models of the concept `MeshDomainField_3`. The behavior and semantic of the arguments are the same as above, except that the radius and distance bound parameters are functionals instead of constants.
