.. py:method:: t3toolbox.manifold.CorewiseGeometry.frame(x)

   .. code-block:: python

      def frame(
              self,
              x:  t3.TuckerTensorTrain,
      ) -> bvf.T3Frame:  # the (U, G, G, G) non-orthonormal frame at x


   The core-parameter frame at ``x``: ``(U, G, G, G)`` (down/left/right all the TT cores ``G``).
