Domain Classes

`#include <CGAL/Mesh_constant_domain_field_3.h>`

## Definition

The class `Mesh_constant_domain_field_3` is a model of concept `MeshDomainField_3`.

It provides a constant field accessible using queries on 3D-points.

The class `Mesh_constant_domain_field_3` can also be customized through `set_size()` operations to become a piecewise constant field, i.e. a sizing field with a constant size on each subpart of the domain.

Template Parameters

  Gt | 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.
  Index | is the type of index of the vertices of the triangulation. It must match the type `Index` of the model of `MeshDomain_3` used in the meshing process.

Is Model Of:
  `MeshDomainField_3`

## Types

typedef Gt::FT | FT
| Numerical type.
typedef Gt::Point_3 | Point_3
| Point type.
typedef Index | Index
| Type of index of the vertices of the triangulation.

## Creation

| Mesh_constant_domain_field_3 (FT size)
| Builds a constant domain field with size `size`.

## Operations

void | set_size (FT size, int dimension, const Index &index)
| Sets the size such as `operator()` will return size `size` at any query point of dimension `dimension` and index `index`.
