#include <CGAL/Classification/Feature/Height_above.h>
CGAL::Classification::Feature_base.
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".
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 . |
