title: Augmented Reality iOS: marker detection and 3D projection
body: <p>I need to develop an iOS app, which can detect marker via iPhone camera and project 3D model on top of this marker.</p>
  
  <p>I was looking all day long for some useful information on this topic, but all I got was brainwashing mix of ARToolkit/OpenCV/NyARToolkit/cpp so on and so on... Being a noob when it comes to compiling and combining libraries I downloaded few sample apps from different sources to see if I can understand, but it was only 'black ready to use' magic.
  Many of the questions on this topic here on SO are from year or two ago, so maybe there is something valuable.</p>
  
  <p>Using iPhone camera or using OpenGL - there a lot of tutorials to start, but detecting markers/iamges and usage of libraries needed for that is something which is making helpless.
  With what and where to start?</p>
