I would like to add few 3D objects in my iPhone application. My application is basically a eBook kind of a application & I would like to embed few 3D objects in 2 to 3 pages. I would like the users to rotate the 3D object and see various angles. Do I need to use any 3D applications such as Unity3D for such applications or I will be able to achieve this using just Objective C. Please help me..thanks.
I'd look at:
http://isgl3d.com/
as it's objective c based.
SIO2 is simple and free 3D engine.

i am new in objective c and in my application i have to draw the 3D image(like carton boy) and rotate it in X axis,Y axis and z axis by using OpenGL ES framework How can i draw the images.someone help me thanks in advance.
If you are making a 3D game in cocos2d project then the 3D parts will have to be loaded using either another framework (like cocos3d) or like you said using OpenGL framework.
cocos3D http://brenwill.com/cocos3d/ works easily with cocos2d and will allow you to load 3d objects and use them in the way you want.
OpenGL framework will be more difficult to understand and use but will give you more flexibility depending on the results you want.
I would solve your question by creating 3D objects in a open source (and free) software like Blender and load them in a cocos3d project, from there, the way to manipulate them the way you want is fairly easy.
I am trying to edit multi targets and image targets sample app of qualcomm sdk so that instead of using openGL , I can only overlay UIKit contents such as buttons text etc just for a simple demo. But I am unable to do so till now.
Please guide me where to make any changes or how to go about it?
I have also referred to the forums and tried to examples but they all are using openGL which i want to get rid of.
Please help me out
The main duty of the QCAR is to give you a 4x4 matrix called ModelView matrix with which you can superimpose your graphics. This is an OpenGL matrix and I don't think that you would be able to use that matrix in UIKIT.
If you only want to overlay some UIs stuff when a target is detected then you don't need that matrix. But the UIs will be on the screen in 2D (not on the target image in 3D scene) and tha't not AR at all.
Another option is to incorporate a rendering engine with QCAR to avoid using pure OpenGL ES APIs. For iPhone I think OpenFramework should do the business.
I want to create an augmented reality application for the iPhone.
To be more specific, I want to create a 3D object of certain dimensions that will be superimposed on the camera's input so that the user can "move around" the object.
Are there any libraries for creating (or at least trying to create..) such objects/applications for the iphone?
You can use the Mobile SDK from metaio: http://www.metaio.com/sdk/
It will be easier to use than ARToolKit, as it abstracts the AR functionality on a higher level, e.g. it has an integrated renderer that lets you load OBJ and MD2 models.
See this version of Augmented Reality Toolkit

Is there a documented example that shows the process of taking 3D models and animations created on blender, and displaying them as part of an iPhone/iPad application?

I am developing a simple iPhone app, which:
retrieves data from the server
presents the data
In order to present the data better I want to add nice 3d dynamic objects, for example:
a car with spinning wheels next to car sales bar chart.
power plant with smoke coming out of the chimney next to CO2 emission numbers
The questions are:
How do I work with the designer on this, what output should he provide for me (format)?
How do I put it in my application, should I involve some 3d engine/framework?
The team behind cocos2D has just announced cocos*3D* and this seems really promising.
The first public beta can be downloaded

You can use cocos2d for the iPhone and fake 3d with the art. So, you have a car that is drawn to look 3d but you're only using 2d to display it. The effects that you want to do don't require to use full 3d models.
You may also have a look at this one I discovered recently:

It's pretty new but well documented and with video demos.
