Define directions with a radial rosette
---------------------------------------
Create a radial rosette and plot the resulting reference directions.
For a radial rosette, a line is constructed that goes through the origin. Its
direction vector is normal to a plane spanned by ``dir1`` and ``dir2``.
Therefore, the reference directions are parallel to the shortest connection from the line to
each point for which it is computed.

Define directions with a cylindrical rosette
--------------------------------------------
Create a cylindrical rosette and plot the resulting reference directions.
For a cylindrical rosette, the reference directions are tangential to the circles around the origin
that lie in a plane spanned by ``dir1`` and ``dir2``.

Define directions with a spherical rosette
------------------------------------------
Create a spherical rosette and plot the resulting reference directions.
For a spherical rosette, the reference directions are tangential to a sphere around the origin.
Note that for this example, the reference directions of the spherical rosette are the same as
those of the cylindrical rosette.

Define directions with an edge-wise rosette
-------------------------------------------
Create an edge-wise rosette and plot the resulting reference directions.
The reference directions are given by a projection of ``dir1``
and the path of the edge set. ``dir1`` of the rosette is projected onto the point
on the edge that is closest to the rosette's origin. This determines the reference directions
along the edge set.
You can reverse the reference directions by inverting ``dir1``.
An element within an OSS gets its reference directions from the direction
of the point on the edge that is closest to the element centroid.
.. GENERATED FROM PYTHON SOURCE LINES 224-226
Create the edge set from the "All_Elements" element set. Because you assigned
120 degrees to the limit angle, all the edges are selected.

Combine rosettes

Assign both rosettes to the OSS and set the rosette selection method to
``RosetteSelectionMethod.MINIMUM_DISTANCE_SUPERPOSED``. This implies that the reference directions
are weighted by the inverse distance to each rosette. Note that the origin of
the rotated rosette is at ``(0,0,0)``.
