Here’s a quick Unity3D Augmented Reality example I made this week using Qualcomm’s free Vuforia for iOS plugin.
In addition to Vuforia, I used the handy open source iTween library & Unity’s AudioListener.GetSpectrumData on a dummy model I made using Blender. The 3 robots are acting as the sound spectrum analyzer, each being tweened in response to a float (decimal) that’s put together from an average from a sound frequency range.
In this case the entire flyer/poster acts as the Image Target. I was surprised to see that it got a 5 star rating in the Target Management System (TMS) on QDevNet (TMS shows up under My Trackables after you create an account).
