Storing structure for section profiles
sectionProfiles(size, angle, type = c("prolate", "oblate"))matrix of axes lengths
orientation angle
prolate or oblate, default class is prolate
section profiles object, either of class prolate or oblate
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 \([0,2\pi]\) these are transformed to \([0,\pi/2]\). 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.
