sectionProfiles {unfoldr}R Documentation

Constuctor section profiles

Description

Storing structure for section profiles

Usage

sectionProfiles(size, angle, type = c("prolate", "oblate"))

Arguments

size

matrix of axes lengths

angle

orientation angle

type

prolate or oblate, default class is prolate

Details

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.

Value

section profiles object, either of class prolate or oblate
