This interface represents the remaining parts of an hyperplane after other parts have been chopped off.
sub-hyperplanes are obtained when parts of an {@link Hyperplane hyperplane} are chopped off by other hyperplanes thatintersect it. The remaining part is a convex region. Such objects appear in {@link BSPTree BSP trees} as the intersection of a cuthyperplane with the convex region which it splits, the chopping hyperplanes are the cut hyperplanes closer to the tree root.
Note that this interface is not intended to be implemented by Apache Commons Math users, it is only intended to be implemented within the library itself. New methods may be added even for minor versions, which breaks compatibility for external implementations.
@param < S> Type of the embedding space.
