How to get camera position on Hololens 2 ?

Hi @Lionel_Brly ,

so far I remember in the post was metnioned the usage "How to get camera position?"

I have only the HoloLens1 but there is no principle difference from the studio side - so that eyewear project should work on both. I will check if I have such project as demo - so far I remember it was working fine when I tested it on the HoloLens 1 some week ago

What I do not think that is a good idea – is to call the setVector function in an interval. The tracking event has it own callback.

in the article "How can we make a 3D Widget on HoloLens visible in front of me every time ?"  I uploaded  an project which is handle  more complex but it used the requested functionality for tracking of the device postion - so you can check it 

Another info which could be helpful is this one : "https://community.ptc.com/t5/Vuforia-Studio/Finding-distance-from-the-model/m-p/647473#M7497"

In the both mentioned link I attached a project which should demonstrate the functionalit and it implies the requested functionality

In the last post , the more relevant information to your issue is this below:

when I open a project it is always there / HoloLens and Mobile/

- the option 'Enable tracking Events' is threre

I checked my Vuforia Studio builder-settings - at the end I added the following options:

...
 "enableDebugLogging": true,
 "publishPreview": true,
 "welcomeDismissed": true,
 "designTimeDropShadows": "HARD",
 "projectsListView": true,
 "annotationsEnabled": true,
 "serverMTG": true,
 "showTrackingEvents": true
}

So belive the option "showTrackingEvents": true has relevance for the mention  display in the 3d container widget UI.  but may be in combination with some of the other options. 

the code :

function magnitute(a1,a2,a3)
{

return Math.sqrt( Math.pow(a1, 2) + Math.pow(a2, 2)+ Math.pow(a3, 2));
}

function cross(a1,a2,a3, b1,b2,b3) 
{
 return [ a2 * b3 - a3 * b2, a3 * b1 - a1 * b3, a1 * b2 - a2 * b1 ];
}
function normalizeVector(a1,a2,a3) {
 var mag = magnitute(a1,a2,a3)
 return new Vector(a1/mag, a2/mag, a3/mag);
};

 $scope.setWidgetProp('label-distance-y', 'y', ( fargs.position[1]+fargs.gaze[1]*scale)-0.08*4);
 $scope.setWidgetProp('label-distance-y', 'z', ( fargs.position[2]+fargs.gaze[2]*scale));
 $scope.setWidgetProp('label-distance-z', 'x', ( fargs.position[0]+fargs.gaze[0]*scale)+0.0);
 $scope.setWidgetProp('label-distance-z', 'y', ( fargs.position[1]+fargs.gaze[1]*scale)-0.08*3);
 $scope.setWidgetProp('label-distance-z', 'z', ( fargs.position[2]+fargs.gaze[2]*scale));

 
 console.info("distance to 0,0,0 World CSYS = :: "+magnitute(fargs.position[0].toFixed(2),fargs.position[1].toFixed(2),fargs.position[2].toFixed(2)) )
 
 $scope.$applyAsync();
});
 

In the parameter eyepos, eyedir and eyeup I created binding to the text property of the lables label-dinstance-x/y/z and are displayed there.

I attached the test project in the mentioned post
