#include <CGAL/Classification/Feature/Verticality.h>
CGAL::Classification::Feature_base.
Feature based on local verticality.
The orientation of the local tangent plane of the considered point can be useful to discriminate facades from the ground. This feature can use normal vectors if available or eigen analysis that estimates tangent planes from local neighborhoods.
Its default name is "verticality".
