CGAL 5.2 - Shape Detection
CGAL::Shape_detection::Torus< Traits > Class Template Reference

#include <CGAL/Shape_detection/Efficient_RANSAC/Torus.h>

Inherits from

CGAL::Shape_detection::Shape_base< Traits >.

Definition

Torus implements Shape_base.

The torus is represented by the symmetry axis, its center on the axis, and the major and minor radii.

Template Parameters
Traitsmust be a model of EfficientRANSACTraits with the additional requirement for tori (see EfficientRANSACTraits documentation).
Examples:
Shape_detection/efficient_RANSAC_with_parameters.cpp.

Public Member Functions

Point_3 center () const
 Center point on symmetry axis.
 
FT major_radius () const
 Major radius of the torus.
