Detailed Description

template<typename TSpace, typename TInternalInteger>
class DGtal::COBAGenericStandardPlaneComputer< TSpace, TInternalInteger >

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

Description of template class 'COBAGenericStandardPlaneComputer'

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 COBAStandardPlaneComputer. Although it uses four instances of COBAStandardPlaneComputer, the recognition is not four times slower. Indeed, recognition stops quickly on bad orthants.

Note on execution times: The user should favor int64_t instead of BigInteger whenever possible (diameter smaller than 500). The speed-up is between 10 and 20 for these diameters. For greater diameters, it is necessary to use BigInteger (see below).

Template Parameters

TSpace	specifies the type of digital space in which lies input digital points. A model of CSpace.
TInternalInteger	specifies the type of integer used in internal computations. The type should be able to hold integers of order (2*D^3)^2 if D is the diameter of the set of digital points. In practice, diameter is limited to 20 for int32_t, diameter is approximately 500 for int64_t, and whatever with BigInteger/GMP integers. For huge diameters, the slow-down is polylogarithmic with the diameter.

typedef SpaceND<3,int> Z3;
typedef COBAGenericStandardPlaneComputer< Z3, int64_t > StandardPlaneComputer;
StandardPlaneComputer plane;
plane.init( 100, 1, 1 ); * diameter is 100, width is 1/1 x sqrt(3) => 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.

Advanced:: All accepted inserted points are stored in the different naive plane computers, but they are stored "transformed". This is why we adapt the iterator on the naive plane computer with a boost::transform_iterator, such that the points are transformed back when accessing to the value of the iterator (notably in begin and end method).

Examples: io/viewers/viewer3D-7-stdplane.cpp.
