## Definition

The concept `TriangleAccessor_3` represents an accessor to a triangulated polyhedral surface, intersection free and without boundaries.

Has Models:
  `CGAL::Triangle_accessor_3<Polyhedron_3<K>,K>`

See Also
  `CGAL::Polyhedral_mesh_domain_3<Polyhedron,IGT,TriangleAccessor>`
  `CGAL::make_mesh_3()`

## Types
typedef unspecified_type | Triangle_3
| Triangle type. More...
typedef unspecified_type | Triangle_iterator
| Triangle iterator type. More...
typedef unspecified_type | Triangle_handle
| Handle to a `Triangle_3`. More...
typedef unspecified_type | Polyhedron
| Polyhedron type.

## Operations
Triangle_iterator | triangles_begin (Polyhedron p)
| Returns a `Triangle_iterator` to visit the triangles of polyhedron `p`.
Triangle_iterator | triangles_end (Polyhedron p)
| Returns the past-the-end iterator for the above iterator.
Triangle_3 | triangle (Triangle_handle h)
| Returns a `Triangle_3` object from handle `h`.

## Member Typedef Documentation

typedef unspecified_type TriangleAccessor_3::Triangle_3

Triangle type.

Must be a model of DefaultConstructible and CopyConstructible.

typedef unspecified_type TriangleAccessor_3::Triangle_handle

Handle to a `Triangle_3`.

Must be constructible from `Triangle_iterator`. It may be `Triangle_Iterator` itself.

typedef unspecified_type TriangleAccessor_3::Triangle_iterator

Triangle iterator type.

Must be a model of InputIterator.
