SnapRoundingTraits_2 Concept Reference
Concepts

Definition

The concept SnapRoundingTraits_2 lists the set of requirements that must be fulfilled by an instance of the Traits template-parameter of the free function CGAL::snap_rounding_2() CGAL::snap_rounding_2<Traits,InputIterator,OutputContainer>(). The list includes the nested types of the geometric primitives used in this class and some function object types for the required predicates on those primitives.

Member Typedef Documentation

typedef unspecified_type SnapRoundingTraits_2::FT

The number type.

This type must fulfill the requirements on FieldNumberType

typedef unspecified_type SnapRoundingTraits_2::To_double

Models the concept RealEmbeddableTraits::ToDouble.

The precision of this operation is of not high significance, as it is only used in the implementation of the heuristic technique to exploit a cluster of kd-trees rather than just one.
