ArrangementLandmarkTraits_2

Definition

The concept ArrangementLandmarkTraits_2 refines the general traits concept by adding operations needed for the landmarks point-location strategy, namely - approximating points and connecting points with a simple x-monotone curve.

A model of this concept must define the Approximate_number_type, which is used to approximate the coordinates of Point_2 instances. It is recommended to define the approximated number type as the built-in double type.

Refines
