## Definition

template<typename Tr>
class CGAL::Mesh_edge_criteria_3< Tr >

The function object class `Mesh_edge_criteria_3` is a model of `MeshEdgeCriteria_3`.

It provides bounds for the size and approximation criteria.

Is model of
  `MeshEdgeCriteria_3`

## Types
typedef Tr::Geom_traits::FT | FT
| Numerical type.

## Creation
template<typename SizingField , typename DistanceField = FT>
| Mesh_edge_criteria_3 (const SizingField &length_bound, const FT &min_length_bound=0, const DistanceField &distance_bound=FT(0))
| returns an object to serve as criteria for edges.

## Constructor & Destructor Documentation

## ◆ Mesh_edge_criteria_3()

template<typename Tr >
template<typename SizingField , typename DistanceField = FT>

CGAL::Mesh_edge_criteria_3< Tr >::Mesh_edge_criteria_3 | ( | const SizingField & | length_bound,
|  | const FT & | min_length_bound = `0`,
|  | const DistanceField & | distance_bound = `FT(0)`
| ) |  |

returns an object to serve as criteria for edges.

Parameters

  length_bound | is an upper bound for the length of the edges which are used to discretize the curves. It can be a functional or a constant.
  min_length_bound | is a desired lower bound for the length of the edges which are used to discretize the curves. Only edges that are longer than this bound will be refined. Using this lower bound can be handy on some domains, but using it may break all the surface topology guarantees of the meshing algorithm. It is not guaranteed to be exactly respected in the output mesh.
  distance_bound | is an upper bound for the distance from the edge to the corresponding 1D feature. It can be a functional or a constant.

Note
  If one parameter is set to 0, then its corresponding criterion is ignored.

Template Parameters

  SizingField | scalar or model of `MeshDomainField_3`
  DistanceField | scalar or model of `MeshDomainField_3`
