Speak for yourself. Nearly twenty years ago I designed an IT architecture
that could only be rendered in 3D - fortunately we had a 3D CAD system
readily available. In 3D systems, it is not the immediate 2D view that is
important, but the ability to change viewpoint in 3D, and so create a 3D
mental model. A 2D image only presents a single view, in practice, engineers
really do think in 3D, and work by relating the 3D back to 2D views. I've
tried thinking in 4D, and, although it's not that hard, it's only
occasionally useful (although a few years back we did have someone working
on 10-D visualisation). (02)

John: No. The brain constructs 3D models by relating sensory info from
multiple modes. The view from both eyes is the obvious example, but vision
is also correlated with somatosensory inputs from all parts of the body.
Ferenc: All I am saying that when we share our mental imagery then we use 2D
representations, whether verbal or graphic. Even when we create pictures in
perspective (seemingly 3D) in paper or on buildings, we use a flat surface,
including our 3D television, etc.
Of course, the informnatio n that we collect comes from various agles, real
or generated synthetically, just like in holography. This does not man that
you can store real things "in depths" without dificulty. Look at all the big
automated storehouses, they use a surface for storing objects, they would
not pub objects beind each other to make access awkward.
Nevertheless we alway say that we examine th underlying problems, the issues
behind the surface, etc. indicating we cannot imagine another arrangment but
gong further ahead and knocking on the walls.
