UILDING TOWERS OF OBJECTS IS
not a difficult task. We don’t even need
to worry about vanishing points, or locating
horizons: we can rely on the perspective that’s
already built into the starting object, and trust
that perspective to be carried through when we
apply our distortions.
The technique is used here to distort boxes
piled on top of each other. The text here deals
with distorting just one box, but it’s easy to
follow through and build a stack of them like
the one above.
Of course, this isn’t a technique reserved
for the somewhat occasional need to pile cash
boxes on top of each other. The principle also
applies to making office blocks twice as high,
or any application which requires doubling up.

Here’s our original box. We can see the lid, which means
we’re viewing it from above: in other words, the entire box
sits below the horizon line (although the handle may stick up
above that line). When another box is added on top, however,
we’ll no longer be able to see that lid, although we may be
able to catch sight of the handle poking up.

Select the first side, and use Free Transform (Ct
Lt) to shear it. Grab the left center handle (not a
corner!) and drag straight down, adding S to keep the
movement vertical: this will move the whole side in the
correct perspective.

HOT TIP
If you need
to distort the
perspective of a
box so that the lid
remains visible,
you’ll find it hard
to distort the lid
itself accurately.
A simple solution
is to duplicate
the lid to a new
document,
and then use
Perspective Crop
(see page 170) to
square it up: you
can then bring it
back and use Free
Transform with
ease, to move
each corner to its
correct location.
2
The first step is to duplicate the box and drag the
copy directly above it. Clearly, this isn’t enough: the
perspective error is glaringly obvious. In order to distort the
box we need to split it into its constituent parts. To do this, use
the Lasso tool to first select one of the sides, and cut it to a
new layer using CSj LSj.
3
Once you’ve made the new layer, you’ll need to go back
down to the duplicate layer (using O[A[) and
cut the other side into a new layer as well. Don’t drag the
layers apart as shown above – I’ve only done that here to show
you how the box has been split up into its three visible faces.
5
Now repeat the process with the opposite side.
Once again, a simple shear moves the side in correct
perspective. There may be a small gap at the top corner
nearest us, which can easily be fixed using a hard-edged
Smudge tool.
6
All that’s left now is the lid. Make sure it’s behind the
two side layers, and shear it using Free Transform once
more to follow the angle of the front edge of the lid. It may be
necessary to erase some stray bits of lid that project out of the
top, but that’s the only adjustment required.
