#include <CGAL/Classification/Feature/Height_below.h>
CGAL::Classification::Feature_base.
Feature based on local height distribution This feature computes the distance between a point's height and the minimum height on the local cell of the planimetric grid.
Its default name is "height_below".
| 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_below (const PointRange &input, PointMap point_map, const Grid &grid) | |
| constructs the feature. | |
Public Member Functions inherited from CGAL::Classification::Feature_base | |
| const std::string & | name () const |
returns the name of the feature (initialized to abstract_feature for Feature_base). | |
| void | set_name (const std::string &name) |
| changes the name of the feature. | |
| virtual float | value (std::size_t index)=0 |
returns the value taken by the feature for at the item for the item at position index. | |
| CGAL::Classification::Feature::Height_below< GeomTraits, PointRange, PointMap >::Height_below | ( | const PointRange & | input, |
| PointMap | point_map, | ||
| const Grid & | grid | ||
| ) |
constructs the feature.
| input | point range. |
| point_map | property map to access the input points. |
| grid | precomputed Planimetric_grid. |
