Transforming and Retouching
Transforming objects in three
dimensions
The 3D Transform filter lets you manipulate a flat,
two-dimensional image as if it were a solid, three-
dimensional object. Take, for example, a
perspective photograph of a cereal box. You specify
the corners of the box using a wire frame, and you
can then manipulate the box as if it were a three-
dimensional object. You can reposition the box,
turn or rotate it, shrink or enlarge it, and change
its field of view.
Transforming and manipulating objects
You can transform a two-dimensional object into
a cube, sphere, or cylinder and manipulate it using
wire frames based on that shape. Cylinders can
include anything from simple objects, such as a
can of soup, to shapes whose sides are lathed, such
as a bottle or a lamp.
You can create and manipulate any grouping of
cubes, spheres, and cylinders in the same image.
For example, you can create and rotate a box, three
spheres, and a bottle together in the same image.
To transform and manipulate an object in three
dimensions:
Select the layer, area, or shape you want to
1
transform. (See "Specifying what to transform" on
page 126.)
Do one of the following:
2
Choose Filter > Render > 3D Transform.
•
• Double-click 3D Transform in the Filters palette.
• Drag the 3D Transform thumbnail from the
Filters palette to the image.
3 Select one of these tools in the dialog box:
Cube ( ) to map the image (such as a file
•
cabinet) to a cubic surface.
Sphere ( ) to map the image (such as a globe or
•
ball) to a spherical surface.
Cylinder ( ) to map the image (such as a can or
•
bottle) to a cylindrical surface.
Drag to create a cubic, cylindrical, or spherical
4
wire frame over the image.
Move or reshape the wire frame, as described
5
later in this section. The anchor points should
line up with the corners of the box, or the top
and bottom of the sphere or cylinder you want
to manipulate.
Manipulate the object in three dimensions, as
6
described later in this section.
Click OK.
7
To move or reshape the wire frame:
Select the selection tool ( ) or direct selection
1
tool ( ) in the 3D Transform dialog box.
Do either of the following:
2
Drag an edge of the wire frame to move the
•
entire frame.
With the direct selection tool, drag an
•
anchor point on the wire frame to move that
anchor point.
Note: The wire frame turns red if you try to make a
wire frame that would be impossible to re-create in
three dimensions.
