title: Augmented Reality SDK for Unity3d
body: <p>I am Unity developer but new to augmented reality. I want to start with the basic tasks for AR in <strong>Unity3D</strong>. But I am confused where and what to start with? I have gone through some of the SDKs like <strong>metaio, vuforia and D'Fusion</strong>. Which SDK is easy to integrate and use? I have gone through asked <a href="https://stackoverflow.com/questions/9227962/qualcomms-vuforia-qcar-vs-metaio-sdk-vs-dfusion-mobile-vs-layar-sdk">question</a>, but it states the benefits and drawbacks of SDKs. There is not enough information about using it in Unity3d.</p>
