CGAL::Classification::Feature::Height_above< GeomTraits, PointRange, PointMap > Class Template Reference

#include <CGAL/Classification/Feature/Height_above.h>

Inherits from

CGAL::Classification::Feature_base.

Definition

Feature based on local height distribution This feature computes the distance between the maximum height on the local cell of the planimetric grid and a point's height.

Its default name is "height_above".

Template Parameters

GeomTraits	model of CGAL Kernel.
PointRange	model of ConstRange. Its iterator type is RandomAccessIterator and its value type is the key type of PointMap.
PointMap	model of ReadablePropertyMap whose key type is the value type of the iterator of PointRange and value type is GeomTraits::Point_3.

Public Member Functions
	Height_above (const PointRange &input, PointMap point_map, const Grid &grid)
	constructs the feature. More...

void	set_name (const std::string &name)
	changes the name of the feature.
