Hello everybody,

 

I would like to have an iterator that starts from a certain seed and
iterates layer after layer around this seed:

For example, for 3D case:

 - iterate the first 26 neighbors, 

 - then the outer layer of neighbors of these 26 neighbors (I guess they are
5*5*5 - 3*3*3 = 98 ?)

 - and so on...

 

Is there such an iterator?

 

Thanks.

 

George
