Another way would be to use a gradient pattern with a texture_map
containing the various wood, or any other, textures to be used.
Advantage: Faster rendering as the object will be much simpler as it can
now be a single base object.
Disadvantage: You must carefully scale the gradient and apply an oposite
scaling to the individual textures.
