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 I have been reading and searching about this and found some out of date discussion about this, and nothing conclusive.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.
