CGAL::Level_interval< FaceHandle > Class Template Reference

#include <CGAL/Level_interval.h>

Definition

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

Examples:
