A class to build a Zonohedron. A class to build a Zonohedron.
A zonohedron is a solid with a closed surface composed only of parallelograms. Given a set of input vectors, a zonohedron is defined
Given a set of input vectors (the sides of the parallelograms), it is defined as the convex hull of all the points which can be costructed by summing
by the convex hull of all the points which can be co together any subset of input vectors.
The surface closing this solid is composed only of flat parallelograms,
(which have the input vectors as sides).
It is always point-symmetric.
Creates a pure-quad mesh (triangular bit-quad), Mesh created by this class are pure-quad meshes (triangular bit-quad),
(faces with 4 vertices are split into quads). (when coplanar vectors are fed, then planar groups of quads can be seen as
forming planar faces with more than 4 vertices).
