#include <CGAL/Bbox_2.h>
An object b of the class Bbox_2 is a bounding box in the two-dimensional Euclidean plane \( \E^2\).
This class is not templated.

Traits must provide a functor Traits::Construct_bbox_2 having an operator returning the bounding box of each object in the range. Traits must also have a member function Traits::Construct_bbox_2 construct_bbox_2_object() const.
