title: How to import 3D models to iOS game
body: <p>am working on iOS 3D game and am new in this field, am not looking for a code, just some advice on how can I get a model designed on 3D max, Blender or Sketchup loaded on my iOS project. For example, in what kind of format do I need to export the model, so I can use it on openGL ES; or what kind of open source library (3D game engine) that might be used to import the model to my project.</p>
  
  <p>thanks in advance :)</p>
