*Default*: None
:rotation:
If the cell is filled with a universe, this element specifies the angles in
degrees about the x, y, and z axes that the filled universe should be
rotated. Should be given as three real numbers.For example, if you wanted to
rotate the filled universe by 90 degrees about the z-axis, the cell element
would look something like:
.. code-block:: xml
<cell fill="..." rotation="0 0 90" />
*Default*: None
:translation:
If the cell is filled with a universe, this element specifies a vector that
is used to translate (shift) the universe. Should be given as three real
numbers.
.. note:: Any translation operation is applied after a rotation, if also
specified.
