`#include <CGAL/Shape_detection/Efficient_RANSAC/Cone.h>`

## Inherits from

CGAL::Shape_detection::Shape_base< Traits >.

## Definition

template<class Traits>
class CGAL::Shape_detection::Cone< Traits >

Cone implements Shape_base.

The cone is represented by its apex, the axis, and the opening angle. This representation models an open infinite single-cone.

Template Parameters

  Traits | must be a model of `EfficientRANSACTraits`.

Examples
  Shape_detection/efficient_RANSAC_with_parameters.cpp.

## Public Member Functions
FT | angle () const
| Opening angle between the axis and the surface of the cone.
Point_3 | apex () const
| Apex of the cone.
Vector_3 | axis () const
| Axis points from the apex into the cone.

| 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
