## Definition

### template<class Nef_polyhedronTraits_3, class Nef_polyhedronItems_3 = CGAL::Default_items<Nef_polyhedronTraits_3> class Nef_polyhedronMarks = bool>
class CGAL::Nef_polyhedron_3< Nef_polyhedronTraits_3, Nef_polyhedronItems_3 >::Volume

A volume is a full-dimensional connected point set in \( \mathbb{R}^3\).

It is bounded by several shells, i.e. a connected part of the boundary incident to a single volume. An entry element to each shell is provided by the iterator range (`shells_begin()`/`shells_end()`). A `Shell_entry_iterator` is assignable to `SFace_handle`.

Creation

There is no need for a user to create a `Volume` explicitly. The class `Nef_polyhedron_3<Traits>` manages the needed volumes internally.

## Types

The following types are the same as in `Nef_polyhedron_3<Traits>`.
typedef unspecified_type | Mark
| type of mark.
typedef unspecified_type | Object_list
| list of Object handles.
typedef unspecified_type | Volume_const_handle
| const handle to Volume.
typedef unspecified_type | Shell_entry_const_iterator
| const iterator over the entries to all shells adjacent to a volume.

## Operations

const Mark & | mark () const
| the mark of `c` .
Shell_entry_const_iterator | shells_begin () const
| const iterator over the entries to all shells adjacent to `c` .
Shell_entry_const_iterator | shells_end () const
| past-the-end iterator.
