All Known Implementing Classes:

StencilImpl

public interface Stencil

A Stencil contains 27 doubles and can be used to represent the relationship between a grid element and its 26 nearest neighbours in 3D. Positions are identified by integer indices relative to the central element, which consequently has the position (0,0,0).
