#include <CGAL/Shape_detection_3/Plane.h>

Inherits from

CGAL::Shape_detection_3::Shape_base< Traits >.

Definition

Plane implements Shape_base.

The plane is represented by the normal vector and the distance to the origin.

Template Parameters
Traitsa model of EfficientRANSACTraits with the additional requirement for planes (see EfficientRANSACTraits documentation).
Examples:
Point_set_shape_detection_3/efficient_RANSAC_basic.cpp, Point_set_shape_detection_3/efficient_RANSAC_parameters.cpp, and Point_set_shape_detection_3/efficient_RANSAC_point_access.cpp.
