title: location-based Augmented Reality Framework (Android, iOS) with 3D Models?
body: <p>I'm looking for a location-based (not marker-based) augmented reality framework allowing 3d models in both Android and iOS.</p>
  
  <p>I'm not interested in POIs (Point-of-interest) where there is already plenty of frameworks and lots of documentation to do it ourselves such as this:

  <p>Basically, using the same kind of principle as in the article above, but instead of displaying just a label, there could be for example a building-size cube; we could go around it, look down &amp; up and the perspective would change accordingly.</p>
  
  <p>Something that feeds the phone GPS coordinates (and 3 angles) to the "point of view" of an overlay OpenGL view and is open enough to let me add what I want to the OpenGL world (maybe using real-world coordinates too), with some optimisation.</p>
  
  <p>it's for integration in an app with other features so using some of the AR browser available out there doesn't work either.</p>
  
  <p>All I could find was pretty expensive.</p>
  
  <p>Thanks in advance.</p>
