Adobe Photoshop Help Using Help | Contents | Index Transforming and Retouching Back 186 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, two balls, and a bottle together in the same image. To add a wire frame: 1 Choose Filter > Render > 3D Transform. 2 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. 3 Drag to create a cubic, cylindrical, or spherical wire frame over the image preview. Note: 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. To move or reshape the wire frame: 1 Select the selection tool or direct selection tool in the 3D Transform dialog box. 2 Do either of the following: • 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. 3 If you are creating a complex cylinder, do any of the following: • To add an anchor point to a cylinder, 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.
