Periodic_2TriangulationTraits_2
and
Periodic_2DelaunayTriangulationTraits_2
if the template parameter Traits
is a model of the DelaunayTriangulationTraits_2
concept.
Periodic_2TriangulationVertexBase_2
Handle
which basically offers the two dereference operators and ->
. The iterators and circulators are all bidirectional and non-mutable. The circulators and iterators are convertible to handles with the same value type, so that whenever a handle appear in the parameter list of a function, an appropriate iterator or circulator can be passed as well. Traits
. Periodic_2_triangulation_traits_2
provides exact predicates and exact constructions if Traits
does. It provides exact predicates but not exact constructions if Filtered_kernel<CK>
with CK
an inexact kernel is used as its first template parameter. Using Exact_predicates_inexact_constructions_kernel
as Traits
provides fast and exact predicates and not exact constructions, using Exact_predicates_exact_constructions_kernel
provides fast and exact predicates and exact constructions. The latter is recommended if the dual constructions and constructions of points, segments, triangles, and tetrahedra are used.
