#include <CGAL/Bbox_2.h>

Definition

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.

bool	do_overlap (const Bbox_2 &bb1, const Bbox_2 &bb2)
	returns `true` iff `bb1` and `bb2` overlap, i.e., iff their intersection is non-empty.

template<class InputIterator >
Bbox_2	bbox_2 (InputIterator begin, InputIterator past_end)
	returns the bounding box of the objects in the range `[first,past_end[`. More...

template<class InputIterator , class Traits >
Bbox_2	bbox_2 (InputIterator begin, InputIterator past_end, const Traits &traits)
	returns the bounding box of the objects in the range `[first,past_end[`. More...

Creation
	Bbox_2 (double x_min, double y_min, double x_max, double y_max)
	introduces a bounding box `b` with lower left corner at `(xmin, ymin)` and with upper right corner at `(xmax, ymax)`.

Operations
bool	operator== (const Bbox_2 &c) const
	Test for equality.

bool	operator!= (const Bbox_2 &q) const
	Test for inequality.

int	dimension () const
	Returns 2.

double	xmin () const

double	ymin () const

double	xmax () const

double	ymax () const

double	min (int i) const
	Returns `xmin()` if `i==0` or `ymin()` if `i==1`. More...

double	max (int i) const
	Returns `xmax()` if `i==0` or `ymax()` if `i==1`. More...

Bbox_2	operator+ (const Bbox_2 &c) const
	returns a bounding box of `b` and `c`.

Bbox_2 &	operator+= (const Bbox_2 &c)
	updates `b` to be the bounding box of `b` and `c` and returns itself.
