CGAL::Nef_nary_union_3< Nef_polyhedron_3 > Class Template Reference

#include <CGAL/Nef_nary_union_3.h>

Definition

This class helps to perform the union of a set of 3D Nef polyhedra efficiently.

It succesively applies the binary union operation of Nef_polyhedron_3, but schedules these union operations in an opportune way. The class is most efficient, if the polyhedra are added in sorted order. Any order that reflects proximity in the three-dimensional space is helpful. To allow saving memory space, the sorting is left to the user. This way the user can generate the polyhedra in a sorted way and add them one by one to Nef_nary_union_3.
