Member Function Documentation

template<int dim>

void gr::Utils::OneRingNeighborhood::get ( int  queryId, int  nElPerDim, typename NeighborhoodType< dim >::type &  nei  )

inline

Parameters

queryId	Linear index of the query
nbElementPerDim	Number of cells in the grid per dimension Total size of the grid is pow(nbElementPerDim, dim).

Returns

An array of the neighboring cells ids. When the query is on the grid boundaries, out of bounds cells ids are marked with -1 in the output array.
