Hi Peyman,

 

I have the same issue but only on an Android device. I load the image direct from storage not by a web request. I think the feature isn't done so far. Maybe it will fixed in the next version.



At the moment I can't help. I will try something more. If I have a solution (or you have already) I will tell you, okay?



[EDIT]



Seconds later after a very small change also the Android versiomn works for me.



This is the code:

// This method is callled after a button was clicked

public void StartTracking()

{

   VuforiaARController.Instance.RegisterVuforiaStartedCallback(CreateImageTargetProjections);

}



private void CreateImageTargetProjections()

{

   var objectTracker = TrackerManager.Instance.GetTracker<ObjectTracker>(); // ObjectTracker with capital 'O' not like the doumentation with lower 'o'

   var dataset = objectTracker.CreateDataSet();

   foreach (var imageTarget in imageTargetFiles) // I have a list of image targets

   {

      imageTarget.Load(); // My special object which loads an image into a Texture2D

      var runtimeImageSource = objectTracker.RuntimeImageSource;

      var imageTargetTexture = imageTarget.AsTexture(); // This was my little change

      var imageSourceIsLoaded = runtimeImageSource.SetImage(

         imageTargetTexture,

         imageTarget.Dimensions.WidthInMeters, // My special object mesures its own dimensions :)

         imageTarget.Name);

      if (imageSourceIsLoaded){

         var trackableBehaviour = dataset.CreateTrackable(runtimeImageSource, imageTarget.Name);

 

         /// Here I have some code to put an object as child to the image target

         projection.transform.parent = trackableBehaviour.transform;

         projection.transform.rotation = Quaternion.Euler(90, 0, 0); // By default my assigned object have to rotat to spawn it correctly but ist only for me

      }

   }

   objectTracker.ActivateDataSet(dataset);

}

Thank you .

Can you Help me to load Image target from storage in Android Step by Step?

Hi @Peyman,

In the provided code txt, you have at the end of the code:

// TODO: add virtual content as child object(s)

This seems to be missing from the implementation. Have you tried @DevInclusify example code? he adds his approach for adding child objects.

Thank you.

3- Create Child (Quad) for ImageTarget (image3 in attach)

3.1-Add Material from Resources to Quad (image3.1 in attach)

4- Create C# Script in Asset and write code (image4 in attach)

4.1-my code is attached

5- add my script to ImageTarget (image5 in attach)

6-build and run

I think this feature is only available in the latest Vuforia, 8.6.7+
