Photoshop actually had a 3D transformation filter in very early versions, but it was later removed for unknown reasons. Then starting from CS3, 3D came back. In this article, we use a small example to show you the three-dimensional capabilities of Photoshop CS4.
Users can now not only import 3D objects generated by MAYA, 3dsMAX, etc., but also directly generate three-dimensional shapes in Photoshop CS4, such as cubes, spheres, soda cans, wine bottles, etc. You have two options: directly convert the plane image into a mapped three-dimensional object; or select the main menu "3D>New Shape From Layer" to create a new three-dimensional object, here we will create a new hat shape.
Figure 1: Create a new three-dimensional object of a hat
You can see the newly created three-dimensional layer in the layer panel. Double-click the Background under Textures of this layer to edit the material of the hat.

Photoshop will create a new empty file, in which we place a flat image that is exactly the size of the canvas. The size and position of this image will affect the final 3D composition.
Figure 3: Place a flat image
Switch to the 3D file just now, and you can see that the flat image has been synthesized into a three-dimensional object. You can view this object through two new sets of tools in the toolbox, which are used to control the 3D object and camera position.
The tools for controlling three-dimensional objects are rotation, scrolling, dragging, sliding and zooming; and the tools for controlling cameras are orbiting, scrolling, panning, walking and zooming. Of course, you can also use the joystick in the upper left corner of the screen, which can also be used to adjust the position, size and angle of 3D objects. The three primary color arrows on the joystick represent the X, Y, and Z axes respectively.

Not only can you use ordinary images for mapping, you can also use brushes and stamps to paint directly on three-dimensional objects, or use Ctrl+E to directly press a flat image into a three-dimensional object. Here I just entered a line of text on the original material to represent .
