function varargout = createSoccerBall()
%CREATESOCCERBALL Create a 3D mesh representing a soccer ball
%
% It is basically a wrapper of the 'bucky' function in matlab.
% [V, E, F] = createSoccerBall
% return vertices, edges and faces that constitute a soccerball
% V is a 60-by-3 array containing vertex coordinates
% E is a 90-by-2 array containing indices of neighbor vertices
% F is a 32-by-1 cell array containing vertex indices of each face
% Example
% [v, f] = createSoccerBall;
% drawMesh(v, f);

% HISTORY
% 2007-01-04 remove unused variables, enhance output processing
% 2010-12-07 clean up edges, uses formatMeshOutput
% get vertices and adjacency matrix of the buckyball
[b, n] = bucky;
% compute edges
[i, j] = find(b);
e = [i j];
e = unique(sort(e, 2), 'rows');
% compute polygons that correspond to each 3D face
f = minConvexHull(n)';
% format output
varargout = formatMeshOutput(nargout, n, e, f);
