area target: Viewer's Location

Hi, there

 

I wonder how to get the Viewer's location in Vuforia Studio, like the image below

It would be critical in many of the usages.

 

Thanks in advanced.

Hi @dsgnrClarK ,

possibly you can activate the tracking event and check the device position, up and  gaze vectors. So you could calculate the vector distance to another object (widget) .Some code like thiis:

$rootScope.$on('tracking', function( tracker,fargs  ) {
  
   console.warn(tracker);console.warn(fargs);//some info about the arguments
   $scope.setWidgetProp("label-3","text","GAZE:(x="+fargs.gaze[0]+",y="+fargs.gaze[1]+","+fargs.gaze[2]+")");
  $scope.setWidgetProp("label-4","text","Position:(x="+fargs.position[0]+",y="+fargs.position[1]+","+fargs.position[2]+")");
  $scope.setWidgetProp("label-5","text","UP:(x="+fargs.up[0]+",y="+fargs.up[1]+","+fargs.up[2]+")");
$scope.$applyAsync();
})


$scope.$on('$ionicView.afterEnter', function() {
  /****************************+
tml3dRenderer.setupTrackingEventsCommand (function(target,eyepos,eyedir,eyeup) {   
  
  $scope.view.wdg["label-3"]['text']= JSON.stringify(target)
})
  **********/
$timeout(console.warn(tml3dRenderer),1500)  
  
})

///////////////////////
$scope.app.trackingLostMessage=function(){
 $scope.setWidgetProp("label-2","text","Tracking LOST");
$scope.$applyAsync();
  }
$scope.app.trackingMessage=function(){
 $scope.setWidgetProp("label-2","text","Tracking OK");
$scope.$applyAsync();
  }

If you want to have the arrow leading path - I think this could be done with the one of the methods of tml3dRenderer  where we have also to feed with the symbol which should be displayed so far I remember.

Hi, @RolandRaytchev 

 

Appreciate for you help. 🙂

 

I access related properties via the code below successfully.

 

$scope.getProps = function(){
  tml3dRenderer.setupTrackingEventsCommand (function(target,eyepos,eyedir,eyeup) {}
}

 

 

Nevertheless, I couldn't make the code below works.

Nothing shown is console.

 

$rootScope.$on('tracking', function( tracker,fargs  ) {
  console.warn(tracker);
  console.warn(fargs);
})

 

 

Furthermore, would you please explain the usage about  Arrow Leading Path?

Or is there any example related to it?

 

Thanks a lot.
