Transforming and Distorting Images
To transform and manipulate an object in three
dimensions:
1
Select the layer, area, or shape you want to
transform.
2
Choose Filter > Render > 3D Transform.
3
Select one of the 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.
4
Drag to create a cubic, cylindrical, or spherical
wire frame over the image.
5
Move or reshape the wire frame, as described
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.
6
Manipulate the object in three dimensions, as
described later in this section.
7
Click OK.
To move or reshape the wire frame:
1
Do either of the following:
•
To move the entire frame, select the selection
tool in the 3D Transform dialog box and drag
an edge of the wire frame.
•
To move an anchor point, select the direct
selection tool in the 3D Transform dialog box
and drag an anchor point on the wire frame.
Note:
The wire frame turns red if you try to make a
wire frame that is impossible to re-create in three
dimensions.
2
If you are creating a complex cylinder, do any of
the following:
•
To add an anchor point, select the add anchor
point tool
in the dialog box, and click the
right side of the wire frame. For example, you
can add an anchor point to more closely fit the
cylindrical wire frame to a picture of a bottle.
•
To change an added anchor point from a
smooth anchor point to a corner anchor point
and vice versa, select the convert anchor point
tool , and click the point. A smooth anchor
point creates a gentle curve when you adjust it;
a corner anchor point creates a sharp corner.
•
To delete an added anchor point, select the
delete anchor point tool
, and click the point.
You can delete only round or diamond-shaped
points.
3
For Field of View, enter a value between 1 and
130. Alternatively, drag the pop-up slider to the left
to increase the apparent field of view, or to the
right to decrease it. This technique can make the
wire frame fit the image better. If you know the
field of view angle used to photograph the image,
you can enter it here.
To manipulate the object in three dimensions:
Do any of the following in the 3D Transform
dialog box:
•
To move the object, click the pan camera
tool
in the dialog box, and drag the object.
