No, unfortunately.

Paintings like this by Andrea Pozzo [1] in Sant'Ignazio (Rome)
http://flickr.com/photo_zoom.gne?id=62278449&size=l
or the Borromini's architectural trompe l'oeil (the
gallery is very short, in reality) at Palazzo Spada (Rome)

seem to suggest the artists were playing with dimensions,
perspectives, and sometimes also (in case of anamorphosis [2])

with hidden informations.

Of course, also modern natural sciences are playing
with extra dimensions (since SR, its operationism, its 
spacetime) and different perspectives (the role of the 
observer in QM; noncommutativity of density matrices 
that convey the knowledge different people might have 
about the same physical system) and informations  
which remain hidden in the usual realistic spacetime
perspective but become evident in a more abstract 
representation, based more on relations between systems
than on systems themselves [3][4][5][6]. But this
is a completely different topic, interesting though.

A very good question!

[1] "Since Perspective is but a Counterfeiting of the Truth,
the Painter is not obliged to make it appear real
when seen from Any part, but from One determinate Point only."
(Andrea Pozzo quoted in M. H. Pirenne, 'Optics, Painting and
Photography', page 90).

[3] "Quite independently of Einstein, it appears
to me that, in providing a systematic foundation
for quantum mechanics, one should start more from
the composition and separation of systems than
has until now (with Dirac, e.g.) been the case.
- This is indeed - as Einstein has correctly felt -
a very fundamental point in quantum mechanics,
which has, moreover, a direct connection with
your reflections about the cut and the possibility
of its being shifted to an arbitrary place."
