.. py:class:: PlainSites(obj, **hints)

   Bases: :py:obj:`httk.atomistic.models.sites.backend.SitesBackend`


   Backend for sites backed by a raw Nx3 list or tuple of numbers (or any Nx3 vector-like).

   The native representation is preserved verbatim (one site per row); the exact rational
   :class:`~httk.core.FracVector` ``reduced_coords`` are built lazily and cached, and ``unwrap``
   returns the original raw object.

   :param obj: The raw reduced-coordinate representation.
   :param \**hints: Backend-selection hints.


   .. py:property:: reduced_coords
      :type: httk.core.FracVector


      Return the reduced coordinates in the canonical representation.

      :return: The exact reduced coordinates.


   .. py:method:: unwrap()

      Return the original coordinate object.

      :return: The raw coordinate representation.
