blank: the output device will use it own optimum flatness setting to image curved paths without unnecessary processing. Path Flatness Leave the Flatness field blank, to allow the final output device to determine optimum flatness for curved paths. 3D content Photoshop CS4 Extended offers features targeted to engineering, architectural, scientific, and medical users. While these users may not seem to be your primary customers, Photoshop images containing three-dimensional (3D) and video content may be part of many types of work. The ability to interpret CAD data and produce a 3D rendering in Photoshop allows product designers to generate photographic product renderings before products are manufactured. Photoshop CS4 Extended CAD data can be interpreted and rendered to generate an image with special properties. A 3D object can be rotated and scaled in space, textures can be modified within Photoshop, and users can paint directly on 3D objects. The expanded 3D features in Photoshop CS4 Extended allow merging 2D art into 3D models, and include the ability to map art onto built-in 3D shapes such as cone, cube, pyramid, sphere, and more. Photoshop images containing 3D content should not present any problems in imaging and print; when placed into Illustrator or InDesign files, they are interpreted as any other Photoshop file. Although not vector objects, 3D objects share one advantage with Smart Objects: scaling the object within the image, or enlarging the image in Photoshop, reinterprets the 3D data and generates a new rendering of the object, so detail is not lost. Consequently, if a Photoshop file containing a 3D object is too small (or of insufficient resolution), scaling the object in Photoshop will produce better results than you'd achieve with a normal photograph. If you need to scale up an image containing 3D content, you'll achieve better results by scaling the image in Photoshop, rather than enlarging it in Illustrator or InDesign. Note that patterns or textures applied to the surface of 3D objects are pixel-based and will lose detail accordingly. To clarify, the edges and details of a 3D object don't lose detail when scaled, but any textures applied to the object will be scaled as any "regular" photographic data would be. To edit 3D objects, choose options from the new 3D menu. To add new light sources, doubleclick the 3D object's thumbnail (indicated by a three-dimensional cube icon) in the Layers palette to activate the 3D Lights panel. Use the 3D Rotate tool and 3D Orbit tool to manipulate 3D objects in space. To edit a texture, double-click the name of the texture in the Layers palette. The texture opens as a separate image in Photoshop. You can perform any edits, including color correction, distortion, painting, and adding new layers-even text layers. Choose File > Save to write the edited image is written back into the 3D file, updating its appearance, or just click back in the parent file. You can also paint directly on a 3D object. 3D Content The 3D cube icon identifies Layer 1 as special 3D content translated from CAD data. The texture sublayers SKY and WETSUIT can be edited, but new texture layers cannot be added. Adobe Creative Suite 4 Printing Guide 65
