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 photograph showing a cereal box in perspective. You can specify the corners of the box using a wireframe, and 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.
You can transform a two-dimensional object into a cube, sphere, or cylinder and manipulate it using wireframes based on that shape. Cylinders can include anything from simple objects, such as a can of soup, to more complex shapes, 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.
Use the Zoom and Hand tools in the 3D Transform dialog box to change your preview of an image. These actions do not modify the transformation itself, only your view of it.
