n DAE. This file format, also known as COLLADA, is used by the video gaming industry.
It was originally developed to facilitate transporting digital content from one creation
tool to another. COLLADA is also a widely supported file format.
n U3D. This file format, short for Universal 3D, allows users to share 3D graphics with
other users who don’t have the 3D modeling program used to design the image. Like
JPEG or TIFF files, U3D files are gradually ing universally available to most
image viewers.
n FL3. This file format is relatively new. FL3 stands for Flash 3D and is a native Adobe
format.
n KMZ. This file format was created and is used by Google Earth. It is specific to the 3D
geography that you see when you explore Google Earth.
When you are finished making changes to a 3D object, you have the option of exporting it as 22
a 3D object rather than saving it as a PSD file. Choose 3D ➪ Export 3D Layer to open the Save
As dialog box. You can choose from several 3D formats to save your object. You can export 3D
objects from Photoshop in all of the above formats except 3DS.
Looking at the 3D Workspace
Before you start creating and working with 3D objects in Photoshop, it is important to be
familiar with the 3D workspace. Because working with 3D requires multiple tools, layers, and
options, the Essentials workspace in Photoshop is inadequate for the job.
In order to work in 3D, it is vital that you change to the 3D workspace so that you have the
3D panel docked and ready to use. Click the Workspace Selector button on the right of the
Tool Options bar to open the drop-down menu, and select 3D. This opens and docks your 3D
panel and closes panels that are not as useful in this environment. The Properties panel
remains along with the Layers panel.
The 3D panel and the Properties panel work together to efficiently provide you with the
options you need to man
