CGAL 5.4 - Classification
CGAL::Classification::Feature::Distance_to_plane< PointRange, PointMap > Class Template Reference

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

Inherits from



Feature based on local distance to a fitted plane.

Characterizing a level of non-planarity can help to identify noisy parts of the input such as vegetation. This feature computes the distance of a point to a locally fitted plane.

Its default name is "distance_to_plane".

Template Parameters
PointRangemodel of ConstRange. Its iterator type is RandomAccessIterator and its value type is the key type of PointMap.
PointMapmodel of ReadablePropertyMap whose key type is the value type of the iterator of PointRange and value type is CGAL::Point_3.
