Dynamic Augmentations

ia mreading my augmentations through a json file which contains the name of the augmentation its type ( image video 3dModel) and its properties like ortate offsetx offsety

etc....

 how can i create these augmenttions dynamially without overridig them as i loop through the objects retrived from the json

Please have a look a the Browsing POIs section in the SDK sample application/documentation.

Best regards

Thank you for your fast reply , but iam not using point of interests this is what iam doing 

//reading json method

//method to check the type of the augmentation 

 switch (objectType)

            {

               case 'image': 

  //create image objects with prop.

  this.createImageDrawable(object,i);

               break;

            

               case 'video': alert("video");

  //create video objects with prop.

               break;

            

               case '3Dmodel': alert("3DModel");

  //create 3dModel objects with prop.

               break;    

               default:  return;

            }

 

}

//create image augmentation 

createImageDrawable:function createImageDrawableFn(object)

{

 

alert("inside createdrawable image");

var imgOne = new AR.ImageResource(object.url); // create the image

var overlayOne = new AR.ImageDrawable(imgOne, 1, {

offsetX: object.offsetX,

offsetY: object.offsetY

});

var pageOne = new AR.Trackable2DObject(this.tracker, object.name, {

drawables: {

cam: overlayOne

}

});

 

alert("end of createdrawable image");

}

 

so lets say i have like 4 objects of type images i will loop and call this createImageDrawable() function but as u can c the last object will be actually initialized and saved the rest are being overrriden 

 

if u have any way so that i can achieve multiple image recognition using this strategy 

 

best regards

 

sorry for the long thread

Note that a "Trackable2DObject" is basically the definition of the target's augmentations.
In order to create a set of augmentations for a single target you have to create them first and then use the list of camDrawables (namely ImageDrawables, VideoDrawables etc.) as drawables.cam attribute of one trackable2DObject.
