Detailed Description

template<typename TPredicate>
struct DGtal::PlaneProbingLNeighborhood< TPredicate >::ClosestGridPoint

Aim: Used to store the closest grid point associated to a vertex of the triangle and two extra boolean values about the local configuration at that vertex.

Description of data structure 'ClosestGridPoint'

More precisely, given a triplet of vectors \( (m_k)_{0 \leq k \leq 2} \) and a point \( q \), let us denote \( v \) the vertex equal to \( q - m_k \). The first boolean value is 'true' iff the predicate returns 'true' on \( v - m_{k+1} \) and,
similarly, the second boolean value is 'true' iff the predicate returns 'true' on \( v - m_{k+2} \) (the indices are taken modulo 3).
