template<typename TKSpace , typename TPointPredicate >

DGtal::uint8_t DGtal::LightImplicitDigitalSurface< TKSpace, TPointPredicate >::Tracker::adjacent	(	Surfel &	s,
		Dimension	d,
		bool	pos
	)		const

inline

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.
