This is also similar to the 2D/3D type of holograms
except that the holographic image is shot from a solid model
that has to be exactly of the same size in which it will
appear in the hologram. This allows a good feel of depth, has
good 'look around' properties and is also used more for
promotional purpose than security. Good model making is a pre
requisite for getting a good 3D hologram.
