class CGAL::Shape_detection::Sphere< Traits >

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.

Public Member Functions
	operator Sphere_3 () const
	Conversion operator to convert to `Sphere_3` type.

Point_3	center () const
	Access to the center.

FT	radius () const
	Access to the radius of the sphere.

	Returns the indices of the points in the input range assigned to this shape.

virtual std::string	info () const
	Returns a string containing the shape type and the numerical parameters.

virtual FT	squared_distance (const Point_3 &p) const =0
	Computes the squared Euclidean distance from the query point `p` to the shape.
