%POLYGONS3D Description of functions operating on 3D polygons.
%
% A 3D polygon is simply a set of 3D points (called vertices) which are
% assumed to be located in the same plane.
% Several functions are provided for computing basic geometrical
% parameters (centroid, angles), or intersections with lines or planes.
