Hello, seems a good solution for Unity. Is there any way without Unity only with the Android SDK? I can't find any way in the VuMarkRenderer to get the rotation for the Marker. Or maybe any idea where i can try to get it? Do i have to decompose the modelViewMatrix_Vuforia?

I'm sorry got it... it is in the Pose Matrix.

I dont know but i would give it a try

I tested it in play mode. Do you think it will be different on a device?

Did you test it in play mode or on a device?

Thank you for the answer, but the position and rotation of the behaviors is always (0,0,0) and (0,0,0,1)

You can get the position and rotation of the marker from the active behaviours of the vumarkTracker.

See the snippet below. It is a smal extraction from the Vumark sample.

public class VuMarkHandler: MonoBehaviour
{

   private VuMarkManager vuMarkManager;
   void start()
   {
      vuMarkManager = TrackerManager.Instance.GetStateManager().GetVuMarkManager();
   }

   void Update()
   {
      foreach(var bhvr in vuMarkManager.GetActiveBehaviours())
      {
         var position = bhvr.transform.position;
         var rotation = bhvr.transform.rotation;
         //hard work goes here
      }
   }
}
