Constructor & Destructor Documentation

◆ Tracker() [1/2]

template<typename TKSpace , typename TSurfelPredicate >
DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::Tracker ( ConstAlias< DigitalSurfaceContainer aSurface,
const Surfel s 
)

Constructor from surface container and surfel.

Parameters
aSurfacethe container describing the surface.
sthe surfel on which the tracker is initialized.

◆ Tracker() [2/2]

template<typename TKSpace , typename TSurfelPredicate >
DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::Tracker ( const Tracker other)

Copy constructor.

Parameters
otherthe object to clone.

◆ ~Tracker()

template<typename TKSpace , typename TSurfelPredicate >
DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::~Tracker ( )

Destructor.

Member Function Documentation

◆ adjacent()

template<typename TKSpace , typename TSurfelPredicate >
uint8_t DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::adjacent ( Surfel s,
Dimension  d,
bool  pos 
) const

Computes the surfel adjacent to 'current()' in the direction [d] along orientation [pos].

Parameters
s(modified) set to the adjacent surfel in the specified direction d and orientation pos if it exists. Otherwise unchanged (method returns 0 in this case).
dany direction different from 'orthDir()'.
poswhen 'true' look in positive direction along [track_dir] axis, 'false' look in negative direction.
Returns
the move code (n=0-3). When 0: no adjacent surfel, otherwise 1-3: adjacent surfel is n-th follower.

◆ current()

template<typename TKSpace , typename TSurfelPredicate >
const Surfel& DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::current ( ) const
Returns
the current surfel on which the tracker is.

◆ move()

template<typename TKSpace , typename TSurfelPredicate >
void DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::move ( const Surfel s)

Moves the tracker to the given valid surfel.

Precondition
'surface().isInside( s )'
Parameters
sthe surfel on which the tracker is moved.

◆ orthDir()

template<typename TKSpace , typename TSurfelPredicate >
Dimension DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::orthDir ( ) const
Returns
the orthogonal direction to the current surfel.

◆ surface()

template<typename TKSpace , typename TSurfelPredicate >
const DigitalSurfaceContainer& DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::surface ( ) const
Returns
the surface container that the Tracker is tracking.

Field Documentation

template<typename TKSpace , typename TSurfelPredicate >
Neighborhood DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::myNeighborhood
private

Definition at line 159 of file ExplicitDigitalSurface.h.

◆ mySurface

template<typename TKSpace , typename TSurfelPredicate >
const DigitalSurfaceContainer& DGtal::ExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::mySurface
private

a reference to the digital surface container on which is the tracker.
