3d in PS CS4

that ship looks very unique and awesome, which software was it done in.

Adobe is bridging the gap between two dimensional and 3 dimensional approaches to creating art. It started with CS3 where we have the ability to import 3D objects into 3D Layers and have some of the same navigational functionalities as 3rd party 3D program. In addition, we can access the textures via the use of Texture Layers. This gives us the flexibility to alter them to match our final vision in post production.
Now we have the long awaited Photoshop CS4 that has upgraded its 3D capabilities greatly from its predecessor. Its 3D engine goes beyond reading the object and its textures. It will allow you to import & add lights to your 3D scene. It will also read and apply Glossiness, Specularity, Bump and Reflection maps. Photoshop reads its texture information off of UV maps (U –Horizontal and V-Vertical). These are basically 2 dimensional images maps that are mapped onto 3 dimensional surfaces. This style of surface mapping allows the most flexibility as to where you apply your textures.
In this tutorial we are going to explore UV mapping in a 3D program and import the 3D object into CS4’s 3D Layers. Then we will discover the great flexibility that we have with the new advances to the texturing engine.
Let’s start with the basic 3D options for creating 3D primitives from single or multiple images. You can access this under the 3D options located on your menu bar. So, Open any image and select the Cube option to create a 3D cube.
If you are a beginner at 3D modeling and texturing, CS4 will help you get familiar with the basic tools and texturing capabilities through its intuitive interface. Primitives are basic 3D shapes such as spheres, cylinders or cubes to name a few. Essentially, CS4 will take any image and place it onto the primitive that you choose. In this example I have chosen a Cube. Let’s learn how to navigate a 3D object.
Take a look at your tools bar and notice that we have something new. You will see a toolset for navigating 3D objects imported into CS4. There are two sets of tools. One set is for the navigation of the object and the other is for the navigation of your camera.

Basic 3D Navigations

When you select any navigational tool a 3D Axis guide automatically appears adjacent to your model that has red, green and blue color designations. These correspond to X, Y and Z axis. On a grid the “X” axis (red) is simply a movement going from left to right. The Y axis (green) is a movement going up or down. And finally, the Z axis (blue) is movement going in or out into the scene.

I've tried it , its quite good..... But, personally, I still prefer to render in my 3d apps and do final postwork in PS..... just my 2 cents.....
