I’m using training course #7 to load my initial model, and then when the user makes a menu selection I wanted to display a new view with data and 3d model. I thought it would be possible to just duplicate the OGLESIntroductionPOD.cpp for the additional POD, but I see now this causes build errors (from duplicate methods: newDemo, drawMesh, renderScene, etc…).  
  
  
  
  
  
I was just curious if you guys had any tips for using multiple POD files in an iphone/ipad app?

Well as usual, and given enough time, I have figured this out on my own. It’s actually not that difficult. I use multiple view controllers and one eagl context.
