AR Video Passthrough

In this tutorial, you will learn how to turn the scene you built in the Build your First AR/MR App tutorial into a stereo pass-through AR experience.


  • ZED Mini.
  • Oculus Rift or HTC Vive; other VR headsets are not officially supported.
  • VR-ready PC (GTX 1070 GPU or greater recommended)

Set Up your ZED Mini

To set up the ZED Mini on your headset, follow our guides for Oculus Rift and HTC Vive. Use the provided straps to attach the cable to the headset, and make sure to plug the USB Type-C cable into your ZED Mini with the arrows facing forward.

Enable Virtual Reality

  • In Unity, Go to Edit -> Project Settings -> Player.

  • On the right under XR Settings, check the box for Virtual Reality Supported. Doing this will add a list of VR SDKs your project supports, which by default includes Oculus and OpenVR (SteamVR).

  • If you’re using Oculus Rift, enable Unknown Sources in the Settings of Oculus Home. This will allow your brand new AR app to play inside the Rift.

Add the Stereo Rig

  • Follow the steps described in the Build Your First AR/MR App tutorial.

  • In your Hierarchy, delete the ZED_Rig_Mono prefab you added in the last tutorial.

  • In the Project window, go to the ZED -> Prefabs folder. Click and drag the ZED_Rig_Stereo prefab into the Hierarchy window.

Run the Scene

Run the scene and put on your headset. Take a look at the sphere and the shadow beneath it. Walk around it, put your hand over and under it. You can also move the sphere in the Scene window and watch it fly across your room. You’ve built your first ZED Mini AR app!


  • To see a similar scene already put together, check out the Planetarium example scene in ZED -> Examples -> Planetarium -> Scene.
  • If you want to disable inside-out positional tracking to use Oculus or Vive external tracking systems, go to ZED Manager and uncheck Enable Positional Tracking. This will automatically switch between tracking methods and allow you to use Oculus Touch or Vive controllers in your AR app.
