CGAL::Shape_detection::Sphere< Traits > Class Template Reference

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

Inherits from

CGAL::Shape_detection::Shape_base< Traits >.

Definition

Sphere implements Shape_base.

The sphere is represented by its center and the radius.

Template Parameters

Traits

must be a model of EfficientRANSACTraits with the additional requirement for spheres (see EfficientRANSACTraits documentation).

Examples:

Shape_detection/efficient_RANSAC_with_parameters.cpp.
