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);
