Constructor & Destructor Documentation

Tracker() [1/2]

template<typename TKSpace , typename TPointPredicate >

DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::Tracker	(	ConstAlias< DigitalSurfaceContainer >	aSurface,
		const Surfel &	s )

Constructor from surface container and surfel.

Parameters

aSurface	the container describing the surface.
s	the surfel on which the tracker is initialized.

Tracker() [2/2]

template<typename TKSpace , typename TPointPredicate >

DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::Tracker

(

const Tracker &

other

)

Copy constructor.

Parameters

other

the object to clone.

~Tracker()

template<typename TKSpace , typename TPointPredicate >

DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::~Tracker

(

)

Destructor.

Member Function Documentation

adjacent()

template<typename TKSpace , typename TPointPredicate >

uint8_t DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::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).
d	any direction different from 'orthDir()'.
pos	when '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 TPointPredicate >

const Surfel & DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::current

(

)

const

Returns

the current surfel on which the tracker is.

move()

template<typename TKSpace , typename TPointPredicate >

void DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::move

(

const Surfel &

s

)

Moves the tracker to the given valid surfel.

Precondition

'surface().isInside( s )'

Parameters

s	the surfel on which the tracker is moved.

orthDir()

template<typename TKSpace , typename TPointPredicate >

Dimension DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::orthDir

(

)

const

Returns

the orthogonal direction to the current surfel.

surface()

template<typename TKSpace , typename TPointPredicate >

const DigitalSurfaceContainer & DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::surface

(

)

const

Returns

the surface container that the Tracker is tracking.

Field Documentation

myNeighborhood

template<typename TKSpace , typename TPointPredicate >

Neighborhood DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::myNeighborhood

private

the current surfel neighborhood, the object that holds the necessary information for determining neighbors.

Definition at line 149 of file ImplicitDigitalSurface.h.

mySurface

template<typename TKSpace , typename TPointPredicate >

const DigitalSurfaceContainer& DGtal::ImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::mySurface

private

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