Constructor & Destructor Documentation

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

Copy constructor.

Parameters
otherthe object to clone.
template<typename TKSpace, typename TSurfelPredicate>
DGtal::LightExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::~Tracker ( )

Destructor.

Member Function Documentation

template<typename TKSpace, typename TSurfelPredicate>
uint8_t DGtal::LightExplicitDigitalSurface< 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.
template<typename TKSpace, typename TSurfelPredicate>
const Surfel& DGtal::LightExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::current ( ) const
Returns
the current surfel on which the tracker is.
template<typename TKSpace, typename TSurfelPredicate>
void DGtal::LightExplicitDigitalSurface< 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.
template<typename TKSpace, typename TSurfelPredicate>
Dimension DGtal::LightExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::orthDir ( ) const
Returns
the orthogonal direction to the current surfel.
template<typename TKSpace, typename TSurfelPredicate>
const DigitalSurfaceContainer& DGtal::LightExplicitDigitalSurface< TKSpace, TSurfelPredicate >::Tracker::surface ( ) const
Returns
the surface container that the Tracker is tracking.

Field Documentation

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

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

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