Thanks for pointing out that issue with the documentation about the empty vuforia-spatial-core-addon folder. I can update the documentation to make that clearer!
Currently, the Virtualizer and Remote Operator (what you’re seeing on localhost:8081) are meant to be run on your desktop/laptop, while your iPhone should run the Vuforia Spatial Toolbox iOS app. If you run that app on your iPhone in the same wifi network as your Edge Server and Virtualizer, and you point your phone at the image target you added to your world object, the phone and the remote operator will be viewing the same AR/VR scene. So if you add some tools to the world using the phone, you will see them pop up in the Remote Operator (localhost:8081). If you add some tools using the Remote Operator, you will see them pop up in your phone’s AR scene. The remote operator allows someone who is anywhere in the world to open up a web browser and collaborate with someone who is doing some tasks in AR.
You’re probably seeing a 3D model of an office space in your Unity project, but ideally you should swap that out with a 3D model of your own environment (you can make one using a Matterport camera or similar, or possibly with some mobile apps nowadays). If you connect 1-6 Microsoft Azure Kinect cameras to the Virtualizer, in addition to seeing your static 3D model of your space you will see a live-updating 3D “video” of everything happening in the space. This helps a lot with collaborating, because you can see your on-location collaborators walking around the space!
To make sure it all works with your 3D model, make sure that the 3D model in Unity is positioned so that the physical location of your world object’s image target is at your Unity scene’s (0,0,0) position. (In the demo example, this is a pattern spray-painted onto the floor). This will synchronize the coordinate systems of the Remote Operator and the Vuforia Spatial Toolbox iOS app. That means if you add a tool to a certain location in your room on the Remote Operator, you will see it in that same spot in AR using the Spatial Toolbox app.
The net result will be an experience like in this video, but customized for your own space instead of this office:
@valentin or @jhobin are there any other documents introducing what the virtualizer is and what user scenarios it is useful for?
