Is there anyway to stream peer to peer video on image target using Vuforia in Hololens? 

Could someone share with me the Vuforia Hololens1 sample asset that was still on the unity store a few weeks ago?

I can't find it anywhere and I don't have a copy of it.

Thanks in advance,

Arnaud

Hello,

so I'm using VS to develop a native app for the magic leap device,

I've successfully reached all the steps before the vuEngineStart function:

init vuforia, creating the engine, creating the device and the image observer... I'm getting the prompt to allow permission to use the camera and I accept it, the license is also ok.

but when I'm reaching to start the Engine via vuEngineStart call, I'm getting a fatal error, with the message: " Received on_device_unavailable ".

I also can't find any resources for native development for Lumin, so are we supposed to follow the same sample as the Android one ?

Thank you for your help !

Hello,

I'm working on a project based on ground planes and image tracking. I currently build it on android mobile device but I want to build it on HMD devices. I own RealWear Glasses (models HMT-1 and Navigator 500) as well as the Google Glass Enterprise Edition 2. I know that those don't support ground planes and device pose. Are there any plans to support those in the future?

Kind regards,

Hi, I download the latest HoloLens sample (v10.4.4) from the AssetsStore and configured the project step by step. Everything is working fine except this weird error that appears in the console at start. It's related to OpenXR Loaders.

NullReferenceException - Vuforia/Scripts/Internal/RuntimeOpenSourceInitializer.cs:119 

I noticed that xrManager.activeLoader stay NULL forever in UnityEditor, is this behaviour desired?

Should I ignore that NullReferenceError at startup in Editor? Will it be fixed in the future? 

class UnityXRBridge : IUnityXRBridge
{
     public UnityXRBridge()
     {
         RegisterCallbacks();
     }

     void RegisterCallbacks()
     {
         var xrSettings = XRGeneralSettings.Instance;
         var xrManager = xrSettings.Manager;

         var xrLoader = xrManager.activeLoader;
         var xrInput = xrLoader.GetLoadedSubsystem<XRInputSubsystem>();

         xrInput.trackingOriginUpdated += TrackingOriginUpdated;
      }

Hello,

I am working on a project where I need to obtain the TargetToCamera Transform from the Hololens 2. I can get the TargetToWorld but not the CameraToWorld very easily, just wondering if there is a way to query the raw TargetToCamera transform from Vuforia directly? 

Thanks,

Hello,

Currently we have a project for Android that we can make drawings on the world using device camera. It works fine on most of phones but when we run the build in Vuzix M400, the drawings arenot being placed on the world. For example when I draw a heart shape on the corner of the table in my Android phone, it stays on the corner of the table. But when I do the same drawing on the same place while using Vuzix M400, drawing is not on the table, it moves with the camera. We think that Vuzix M400 is not supporting device tracking but we are not sure and we could not find the answer. If so, which HMD device/AR Glass -like M400- would you reccomend to use in order to use it with a Vuforia project.
