Detailed Description

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

Aim: A class that recognizes pieces of digital planes of given diagonal width. When the width is \(1 \times \sqrt{3}\), it corresponds to standard planes. Contrary to ChordStandardPlaneComputer, the axis is not specified at initialization of the object. This class uses four instances of ChordStandardPlaneComputer of axis z, by transforming points \((x,y,z)\) to \((x \pm z, y \pm z, z)\).

Description of template class 'ChordGenericStandardPlaneComputer'

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 four instances of ChordStandardNaiveComputer, the recognition is not four times slower. Indeed, recognition stops quickly on bad diagonal axes.

Template Parameters
TSpacespecifies the digital space (provides dimension and types for the primitive)
TInputPointspecifies 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.
TInternalScalarspecifies 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 ChordGenericStandardPlaneComputer< Z3, Z3::Point, int64_t > StandardPlaneComputer;
StandardPlaneComputer plane;
plane.init( 1, 1 ); // width is 1/1 => standard
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 standard 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.
