createRhombododecahedron()
function varargout = createRhombododecahedron()
%CREATERHOMBODODECAHEDRON Create a 3D mesh representing a rhombododecahedron
%
%   [V E F] = createRhombododecahedron
%   V is a 14-by-3 array with vertex coordinate, 
%   E is a 12-by-2 array containing indices of neighbour vertices,
%   F is a 8-by-3 array containing vertices array of each face.
%
%   [V F] = createRhombododecahedron;
%   Returns only the vertices and the face vertex indices.
%
%   MESH = createRhombododecahedron;
%   Returns the data as a mesh structure, with fields 'vertices', 'edges'
%   and 'faces'.
%
%   Example
%   [v e f] = createRhombododecahedron;
%   drawMesh(v, f);
