Not sure about these sort of things does this also mean that if looking at a photograph, we'll see
distorted lines when they aren't distorted ?

  It doesn't sound very scientific to me. Since when
are there "underlying mechanisms" for curve and
corner perception? Depth perception, to render 3-D
vision, depends on the play of light. I don't see any
need to make up new mechanisms to explain that
phenomenon.

  The links are broken on that page. The scientist
seems to be legitimate, but seems to specialize
in "is-it-a-vase-or-is-it-a-face" research. At least
my taxes are not funding this one. :)

What do you mean by that ?

Well there must be a reason why we see a corner or a curve otherwise this wouldnlt work on anyone.

| Where is the 3D in this ?

  We see a corner because the meeting of the two lines
looks like shading from a 3-D object. It's the same
effect used on computer OS buttons and windows.
Put a black line on two sides and a white line on two
sides and it looks like the button is either depressed
or protruding.

  In other words, this optical illusion is resulting from
the mind's eye guessing at the object based on the
information it has. The clues point to a 3-D corner
with lighting coming from one side, so the mind
completes the image by squaring the corners.
