Sometimes you need to create a 3D software box, hardcover book, or other box-like object in a pinch. It could be done the long way by using a 3D program, or you could even take a digital photo of the real item. However, a fairly good result can be achieved with nothing more than a 2D image of the cover of the box and Photoshop.
Learn how to wrap a texture around a real object, such as a person. The same effect can be applied to beveled text, 3d models, and other objects with depth that cannot be effectively wrapped by simply covering them with a texture image.
