3D 3d in PS CS4

What type of file format does a 3d file have to be saved, in order to manipulate it in PS

Not sure of all the formats, but I do know *.3ds is one of them. 3D Studio Max, various AutoDesk apps, and several other 3d programs will save as *.3ds

Working with 3D content offers many benefits. Although learning the fundamentals of 3D workflow and design is a challenge, once you know the basics you can quickly use a mix of 3D models and 2D imagery (as backgrounds or textures) to build a scene inside Photoshop or your favored 3D application. One advantage to this is that you can quickly simulate a large array of lighting conditions, camera perspectives, and other photographic techniques that would take days of work in the field. Photoshop includes many improvements to 3D workflow, such as a more powerful rendering engine and the ability to create and manipulate various kinds of lights and materials.
 
"3D" is often mentioned in this forum. There is a difference between between 3D as referred to in PS and 3D in the object modeling world.

What we have in PhotoShop is 2 dimensional - HEIGHT, WIDTH. Whereas the other 3D has an extra - depth. This is the true 3D - 3 dimensional. We exist in a 3D Scene. In PS , depth is more an an "ILLUSION" - of how an object or scene appears as viewed from an angle. But everything you're looking at is on a flat plane - a piece of paper for instance. Which is why I wonder... when a person creates a 3D image done in PS, is that the correct term?

There are many formats of a true 3D file depending on native format ( .lws - LIGHTWAVE, hxn - HEXAGON , max - 3DMax , etc) or file format ( .obj -OBJECT , .3ds - 3D file ) The last 2 can be opened in almost any 3D apps. The objects and scenes in 3D can be viewed and set from any angle including top and bottom. These can not be opened in Photoshop. Only the final render of the scene can be manipulated - POSTWORK as we call it.

To show what codmark meant, here's an example - created years ago in my early feeble attempts at 3D rendering.... The DS9 Station was created in LIGHTWAVE format (not my model - a freebie) ; exported and rendered in POSER. Everything behind the DS9 Station was done in PS4 (or was it 5?) (the POSTWORK).

**don't mind this part, SOP for 3D renders everywhere....

that image is so cool .I would go crazy seeing the detail in layers ......
 
I'm still outstation, Can't check the records.

But that was a huge file. And at Pentium II, that was a slow object render. With multiple PS made starfields to get the look I like . There's color layers at different opacities. The planet surface and cloud cover? It started out with PS Cloud filter . The Station consists of a few layers so I can add extra lighting - shadows and highlites - to wake up the original lighting and rigging done in POSER.

Glad you like it.
 
To the original question:
Photoshop can open the following 3D formats: U3D, 3DS, OBJ, DAE (Collada), and KMZ (Google Earth).

Can Now????? An object file? :)That's an eye opener.... Wait til I get home.....

Would that be through a bridge apps like PS Bridge? Or directly.....

My Bad... disregard the lat statement in my post.

Thank for that nifty info, hawkeye.
 
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.....
