title: Open GL 3D library for iOS (and Android)?
body: <p>Is there some free and easy to use 3D library for iOS (and Android) that simplifies Open GL ES framework. Just like there is cool WebGL library: <a href="https://github.com/mrdoob/three.js/" rel="nofollow">ThreeJS</a> for javascript.</p>
  
  <p>So far I saw <a href="http://unity3d.com/" rel="nofollow">Unity</a> but it's not free and I would like something simplified.</p>
  
  <p>My usage would be setting the scene, meshes, camera, rotating the camera etc...</p>
