`Delaunay.``add_points`(points, restart=False)

  Process a set of additional new points.

  Parameters: | points : ndarray New points to add. The dimensionality should match that of the initial points. restart : bool, optional Whether to restart processing from scratch, rather than adding points incrementally.
  Raises: | QhullError Raised when Qhull encounters an error condition, such as geometrical degeneracy when options to resolve are not enabled.

  Notes

  You need to specify `incremental=True` when constructing the object to be able to add points incrementally. Incremental addition of points is also not possible after `close` has been called.
