Yes, this is the basic principle, but in order for the computer
to create this second viewpoint, it must know the coordinates
in space (x, y, z) of every object in space.  This information 
does not exist in the 2d picture.  It must be provided by the
human operator.  So only with considerable human input it
is possible for the computer to create a 3D picture out of
a 2D one.  Of course, the other extreme is the conversion
of works of art from 2D to 3D.  In this case since the scene
is imaginary (not real) all the depth information is in the mind
of the artist who performs the conversion (with the help of
the computer).
