Understanding Spatial Anchors
Im currently using the the Holograms 240 project to sync an experience between multiple devices.The official microsoft dev page describes anchors a bit but Im trying to understand them in a bit more detail.
So suppose my initial Hololens device starts and it needs to create the anchors. From what I understand, it scans the room and searches for identifiable physical objects? So would it see a bottle of water, and register that physical object as the anchor? (Not sure)
Are spatial anchors determined purely by geometric characteristics? Or can anchors be identified by something such as color (Such as bright red piece of paper on the floor)
How does hololens choose what will be the spatial anchor when there are various potential anchors in the room?
Would it be possible to record a specific physical anchor, and clamp the experience to only search for that anchor? Kind of like how Vurforia uses image targets?
Im trying to streamline my AR experience and remove that waiting time of searching for anchors, creating anchors, sending anchor data across the sharing service and so on. Rather, Id just want all hololens devices in the expereince to search for a single real world reference point and not worry about learning about environment over the time. (I can guarantee a static anchor/reference point on start up for my current project)
