Detailed Description

template<typename TSpace, typename TInputPoint, typename TInternalScalar>
class DGtal::ChordGenericNaivePlaneComputer< TSpace, TInputPoint, TInternalScalar >

Aim: A class that recognizes pieces of digital planes of given axis width. When the width is 1, it corresponds to naive planes. Contrary to ChordNaivePlaneComputer, the axis is not specified at initialization of the object. This class uses three instances of ChordNaivePlaneComputer, one per axis.

Description of template class 'ChordGenericNaivePlaneComputer'

As a (3D) geometric primitive computer, it obeys the concept CAdditivePrimitiveComputer. It is copy constructible, assignable. It has methods extend(), extend( InputIterator, InputIterator) and isExtendable(), isExtendable(InputIterator, InputIterator). The object stores all the distinct points p such that 'extend(p )' was successful. It is thus a model of boost::ForwardContainer (non mutable). It is iterable (inner type ConstIterator, begin(), end()). You may clear() it.

It is also a model of concepts::CPointPredicate (returns 'true' iff a point is within the current bounds).

Note on complexity: See ChordNaivePlaneComputer and Comparative evaluation of COBA and Chord algorithm. Although it uses three instances of ChordNaivePlaneComputer, the recognition is not three times slower. Indeed, recognition stops quickly on bad axes.

Template Parameters

TSpace	specifies the digital space (provides dimension and types for the primitive)
TInputPoint	specifies the type of the input points (digital or not). Usually, you may choose TInputPoint = TSpace::Point, but this is not compulsory. You may for instance wish to manipulate floating-point value points. This is possible, but you have to choose the type TInternalScalar accordingly.
TInternalScalar	specifies the type of scalar used in internal computations, generally a more precise type than TInputPoint::Component. For instance, for digital points, the type should be able to hold integers of order \((2*D)^2\) if D is the diameter of the set of digital points.

typedef SpaceND<3,int> Z3;
typedef ChordGenericNaivePlaneComputer< Z3, Z3::Point, int64_t > NaivePlaneComputer;
NaivePlaneComputer plane;
plane.init( 1, 1 ); // width is 1/1 => naive
plane.extend( Point( 10, 0, 0 ) ); // return 'true'
plane.extend( Point( 0, 8, 0 ) );  // return 'true'
plane.extend( Point( 0, 0, 6 ) );  // return 'true'
plane.extend( Point( 5, 5, 5 ) );  // return 'false'
//There is no naive plane going through the 3 first points and the last one.

Model of boost::DefaultConstructible, boost::CopyConstructible, boost::Assignable, boost::ForwardContainer, concepts::CAdditivePrimitiveComputer, concepts::CPointPredicate.

Note: The returned primitive has the form \(\mu \le \vec{N} \cdot \vec{X} \le \mu + \epsilon\). It is guaranteed that its axis width is strictly less than the value widthNumerator / widthDenominator specified with method init.

◆ selfDisplay()

template<typename TSpace , typename TInputPoint , typename TInternalScalar >

void DGtal::ChordGenericNaivePlaneComputer< TSpace, TInputPoint, TInternalScalar >::selfDisplay ( std::ostream & out ) const
