## Definition

The concept `MeshDomainField_3` describes a scalar field which could be queried at any point of the space.

Has Models:
  `CGAL::Mesh_constant_domain_field_3<Gt,Index>`

See Also
  `MeshDomain_3`
  `MeshDomainWithFeatures_3`
  `CGAL::Mesh_edge_criteria_3<Tr>`
  `CGAL::Mesh_facet_criteria_3<Tr>`

## Types
typedef unspecified_type | FT
| Numerical type.
typedef unspecified_type | Point_3
| Point type.
typedef unspecified_type | Index
| Index type for points. More...

## Operations
The `operator()` returns the field value at a query point. The field value may depend on the query point location and/or on the input feature including the query point.
FT | operator() (const Point_3 &p, int dimension, const Index &index) 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 vertex index `index`.
