Definition

template<typename VertexBase, typename CellBase, typename ConcurrencyTag>
class CGAL::Triangulation_data_structure_3< VertexBase, CellBase, ConcurrencyTag >

The class Triangulation_data_structure_3 stores a 3D-triangulation data structure and provides the optional geometric functionalities to be used as a parameter for a 3D-geometric triangulation (see Chapter 3D Triangulations).

The vertices and cells are stored in two nested containers, which are implemented using Compact_container (or Concurrent_compact_container, see below). The class may offer some flexibility for the choice of container in the future, in the form of additional template parameters.

Template Parameters

VertexBase	must be a model of TriangulationDSVertexBase_3. The default is Triangulation_ds_vertex_base_3<TDS>.
CellBase	must be a model of TriangulationDSCellBase_3. The default is Triangulation_ds_cell_base_3<TDS>.
ConcurrencyTag	enables the use of a concurrent container to store vertices and cells. It can be Sequential_tag (use of a Compact_container to store vertices and cells) or Parallel_tag (use of a Concurrent_compact_container). If it is Parallel_tag, the following functions can be called concurrently: create_vertex(), create_cell(), delete_vertex(), and delete_cell(). Sequential_tag is the default value.

Is model of

TriangulationDataStructure_3

The base class Triangulation_utils_3 defines basic computations on indices of vertices and neighbors of cells.

Cell

template<typename VertexBase , typename CellBase , typename ConcurrencyTag >

typedef CellBase::template Rebind_TDS<Tds>::Other CGAL::Triangulation_data_structure_3< VertexBase, CellBase, ConcurrencyTag >::Cell

The face type.

Cell_range

template<typename VertexBase , typename CellBase , typename ConcurrencyTag >

typedef Compact_container<Cell, Default> CGAL::Triangulation_data_structure_3< VertexBase, CellBase, ConcurrencyTag >::Cell_range

Cell container type.

If ConcurrencyTag is Parallel_tag, a Concurrent_compact_container is used instead of a Compact_container.

typedef VertexBase::template Rebind_TDS<Tds>::Other CGAL::Triangulation_data_structure_3< VertexBase, CellBase, ConcurrencyTag >::Vertex

Vertex_range

template<typename VertexBase , typename CellBase , typename ConcurrencyTag >

typedef Compact_container<Vertex, Default> CGAL::Triangulation_data_structure_3< VertexBase, CellBase, ConcurrencyTag >::Vertex_range

Vertex container type.

If ConcurrencyTag is Parallel_tag, a Concurrent_compact_container is used instead of a Compact_container.
