SubHyperplane
.
sub-hyperplanes are obtained when parts of an hyperplane
are chopped off by other hyperplanes that
intersect it. The remaining part is a convex region. Such objects appear in BSP trees
as the
intersection of a cut hyperplane with the convex region which it splits, the chopping hyperplanes are the cut
hyperplanes closer to the tree root.

The instance created is completely independent of the original one. A deep copy is used, none of the underlying objects are shared (except for the nodes attributes and immutable objects).

public Region<T> getRemainingRegion()
The returned region is expressed in the canonical hyperplane frame and has the hyperplane dimension. For example a chopped hyperplane in the 3D euclidean is a 2D plane and the corresponding region is a convex 2D polygon.

- other sub-hyperplane to union (must be in the
same hyperplane as the instance)public AbstractSubHyperplane<S,T> applyTransform(Transform<S,T> transform)
The instance must be a (D-1)-dimension sub-hyperplane with respect to the transform not a (D-2)-dimension sub-hyperplane the transform knows how to transform by itself. The transform will consist in transforming first the hyperplane and then the all region using the various methods provided by the transform.
