title: 3D Programming in Objective-C "Only"
body: <p>[I'm going to be interviewed for a position, and I don't want to oversell myself...]</p>
  
  <p>I can do just about anything in Objective-C (some things need a lot of code) in 2D, but I haven't actually learned any C fundamentals (except as related to Obj-C). For instance, if an Array is not an <code>NSArray</code> I don't know how to work with it. That said, I feel comfortable doing 2D animations in Objective-C using <code>UIView</code> animations or using Core Animation directly.</p>
  
  <p>Without knowing C, is it possible to work in 3D (or even do 3D games) on the iPhone? I think I'm asking about OpenGL ES, but that might not be the only option...? </p>
