The cell base required by the basic triangulation does not need to store any geometric information, so only the requirements of the triangulation data structure apply.

However, for the Delaunay triangulation, the ability to store the circumcenter is provided (for optimization reasons), hence an additional requirement only in this case, and only when the dual functions are called.
