Why would anyone attempt to teach about the 4th dimension in art, especially visual?

answers1: Why not ask the teacher? <br>
Someone who might know a little more about the subject than you do <br>
(I imagine).
answers2: The teacher I had knew better, I geuss.
answers3: You can try through twin paradox, as time is the fourth
dimension, if a twin stay on earth and the other travels very very
fast, thing difficultly achieved with my car, to another point in the
universe, when he or she returns his/her brother or sister will be
much much older than his or her. Just a theory, but atom particles
seem to behave this way
answers4: The teacher probably went to an art school that concentrated
on conceptual art and not the technical aspects of actually producing
art! Talk is interesting, but sometime you have to actually do it. A
real artist actually creates real art.
answers5: Strange concept. I'm not sure what the 4th dimension in art
is. The 3 dimensions are height, width, depth. It's easy to represent
those in art. The 4th dimension the way you are talking about it is
something hidden or inside something else. It's always compelling to
add some mystery to a painting so the viewer can ask: what's going to
happen next, or wonder what's inside that. I think of the 4th
dimension as being time and that does not exist unless the art is a
mobil or something like that. Now that I think of that, I painted a
piece a couple of years ago, a landscape, where a storm was coming up,
and the trees were blowing in one direction. Moving air = 4th
dimension. The effects were represented but you couldn't see the air.

If you look at some of the cubist paintings you will see features
represented at different angles. For example a face looking forward
with the nose viewed from the left and eyes from the right. That could
be broadly described as a 4th dimension.
answers6: as even the visual arts are about representing the
non-visual, it makes sense to include the fourth dimension. art is
about what cannot be simply referred to with the senses we're familiar
with, nor language. I suppose you agree there's a difference between a
painting not including depth, and one (still being a painting so
actually a two-dimensional product) depicting a life scene like people
in a room
