Add More Dimension to Your World: Two-Point Perspective chapter 7
This photo of a coffee table is an example of two-point per-
spective, with the front and back of the table converging
toward one vanishing point, and the two sides converging
toward two different vanishing points. However, if you look
carefully, you will notice that the books are slightly skewed,
and if you were to draw them accurately, their sides would
converge toward a separate vanishing point.
The cappuccino maker has its own two vanishing points, and
the salt-and-pepper shakers have their own vanishing points
(each of them is at a different angle to the cappuccino
maker). However, as all of the elements in this photo are
viewed from the same eye level, all of the vanishing points fall
on the same horizon line.
