\ccDefinition
|
|
|
|
The Delaunay refinement process involved in the
|
|
template functions \ccc{make_mesh_3} and \ccc{refine_mesh_3}
|
|
is guided by a set of elementary refinement criteria
|
|
that concern either mesh tetrahedra or surface facets.
|
|
The concept \ccRefName\ describes the types that
|
|
handle the refinement criteria for surface facets.
|
|
|
|
|
|
\ccTypes
|
|
|
|
\ccNestedType{Facet}{Type for the facets of the
|
|
triangulation. Must match the \ccc{Facet} type in the
|
|
triangulation type used by the mesh generation function.}
|
|
|
|
\ccNestedType{Cell_handle}{Handle type for the cells of the
|
|
triangulation. Must match the \ccc{Cell_handle} type in the
|
|
triangulation type used by the mesh generation function.}
|
|
|
|
\ccNestedType{Facet_quality}{Type representing the quality of a
|
|
facet. Must be a model of CopyConstructible and
|
|
LessThanComparable. Between two facets, the one which has the lower
|
|
quality must have the lower \ccc{Facet_quality}.}
|
|
|
|
\ccNestedType{Is_facet_bad}{Type representing if a facet is bad or not. This type
|
|
must be convertible to \ccc{bool}. If it converts to \ccc{true} then the facet is bad, otherwise
|
|
the facet is good with regard to the criteria.
|
|
|
|
In addition, an object of this type must contain an object of type
|
|
\ccc{Facet_quality} if it represents
|
|
a bad facet. \ccc{Facet_quality} must be accessible by
|
|
\ccc{operator*()}. Note that \ccc{boost::optional<Facet_quality>} is
|
|
a natural model of this concept} % boost::optional
|
|
|
|
\ccCreationVariable{facet_criteria}
|
|
|
|
\ccOperations
|
|
|
|
\ccMethod{Is_facet_bad operator()(Facet f);}
|
|
{Returns \ccc{Is_facet_bad} value of facet \ccc{f}.}
|
|
\ccMethod{Is_facet_bad operator()(Cell_handle c, int i);}
|
|
{Same as above with \ccc{f=(c,i)}.}
