Detailed Description

template<typename TDigitalSurfaceTracker>
class DGtal::DigitalSurface2DSlice< TDigitalSurfaceTracker >

Aim: Represents a 2-dimensional slice in a DigitalSurface. In a sense, it is a 4-connected contour, open or not. To be valid, it must be connected to some digital surface and a starting surfel.

Description of template class 'DigitalSurface2DSlice'

It provides the following inner types:

  • ConstIterator
  • ConstReverseIterator
  • ConstCirculator
  • ConstReverseCirculator

And the following (circular)iterator services:

  • begin() : begin ConstIterator
  • end() : end ConstIterator
  • rbegin() : begin ConstReverseIterator
  • rend() : end ConstReverseIterator
  • c() : ConstCirculator
  • rc() : ConstReverseCirculator

You can use these services to iterate over the elements. Note that c() and rc() are defined so as to start on the same surfel (when dereferenced). The same is true for cstart() and rcstart(). You should use circulators when isClosed() is true, otherwise it will connect unconnected surfels (the two extremities of the open slice contour).

Template Parameters
TDigitalSurfaceTrackerany model of CDigitalSurfaceTracker: the concrete representation chosen for tracking the digital surface.

Constructor & Destructor Documentation

◆ ~DigitalSurface2DSlice()

template<typename TDigitalSurfaceTracker >
DGtal::DigitalSurface2DSlice< TDigitalSurfaceTracker >::~DigitalSurface2DSlice ( )

Destructor.

◆ DigitalSurface2DSlice() [1/3]

template<typename TDigitalSurfaceTracker >
DGtal::DigitalSurface2DSlice< TDigitalSurfaceTracker >::DigitalSurface2DSlice ( DigitalSurfaceTracker *  tracker,
Dimension  i 
)

Constructor from tracker and Dimension. The current position of the tracker gives the starting surfel s. The 2D slice spans a 2D-plane containing axes i and sOrthDir( s ).

Parameters
trackera pointer on a tracker, which will be moved to build the slice. More precisely, if the contour is open, the tracker is moved to the first surfel when traversing in the direct orientation. If the contour is closed, the tracker is returned at the same position.
ia direction different from the orthogonal direction of the current surfel of the tracker.

NB: O(n) complexity (at least) if n is the number of surfels of the slice.

◆ DigitalSurface2DSlice() [2/3]

template<typename TDigitalSurfaceTracker >
DGtal::DigitalSurface2DSlice< TDigitalSurfaceTracker >::DigitalSurface2DSlice ( )

template<typename TDigitalSurfaceTracker >
DGtal::DigitalSurface2DSlice< TDigitalSurfaceTracker >::DigitalSurface2DSlice ( const DigitalSurface2DSlice< TDigitalSurfaceTracker > &  other)
private

Copy constructor.

Parameters
otherthe object to clone. Forbidden by default.
