The function aggregates the necessary data for the trivariate unfolding procedure either for type
prolate
or oblate
spheroids. Argument size
is a numeric matrix which contains the
axes lengths (first column corresponds to major semi-axis, second one to minor semi-axis). The angle
is the orientation angle between the major axis and the vertical axis direction in the section plane.
If the angles range within [0,2π] these are transformed to [0,π/2]. The function returns a
list which consists of either longer or shorter axis A
of section profiles corresponding to the type
of spheroids which are intended to be reconstructed, the aspect ratio as the shape parameter S
with
values in (0,1], and the orientation angle alpha
.
