I am new to 3D modeling. I have a request to show 3D model in iPad. I have been reading and searching about this and found some out of date discussion about this, and nothing conclusive. I wish to display 3D (probably .obj file) model so the use will be able rotate it. Can you please give me points where to start. OpenGL? Unity? Cocos? I have read this post:

Want to display a 3D model on the iPhone: how to get started?

But its from 2009, in app development time it is ancient... Maybe there is some thing new in this area.

    If loading .obj files is what you want, you can refer to these more recent questions: [Best way to load a obj file on iOS](http://stackoverflow.com/questions/11497380/best-way-to-load-a-obj-file-on-ios) and [Loading 3D model in iOS](http://stackoverflow.com/questions/9697348/loading-3d-model-in-ios). Loading and displaying 3-D models in general is a pretty broad topic, so you might need to be a little more specific to set this question apart from the many others like it that have come up since the one you point to. – Brad Larson Jun 04 '13 at 13:59

here's some links from a little bit of research

these links provide nice information regarding your post, but as far as i can find, there are no concrete tutorials about doing this. You might need to build a 3D model in another program that you are more familiar with to get the concepts down and then try to mimic it in ios
