bbox_3() [1/2]

template<class InputIterator >

Bbox_3 bbox_3 ( InputIterator  begin, InputIterator  past_end  )

related

returns the bounding box of the objects in the range [first,past_end[.

Each object in the range must have a member function BBox_3 bbox() returning its bounding box.

bbox_3() [2/2]

template<class InputIterator , class Traits >

Bbox_3 bbox_3 ( InputIterator  begin, InputIterator  past_end, const Traits &  traits  )

related

returns the bounding box of the objects in the range [first,past_end[.

Traits must provide a functor Traits::Construct_bbox_3 having an operator returning the bounding box of each object in the range. Traits must also have a member function Traits::Construct_bbox_3 construct_bbox_3_object() const.
