◆ bbox_3() [1/2]
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]
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
.
