CGAL::Level_interval< FaceHandle > Class Template Reference

#include <CGAL/Level_interval.h>

Definition

template<typename FaceHandle>
class CGAL::Level_interval< FaceHandle >

The class Level_interval represents intervals for the minimum and maximum value of the z-coordinate of a face of a triangulation.

Template Parameters

FaceHandle

must be a handle with the value type Face, which must have a nested type Vertex, which must have a nested type Point, whose Kernel_traits<Point>::Kernel must have a nested type FT. These requirements are fulfilled, if one uses a CGAL triangulation and a CGAL Kernel.

Is model of

Interval
