In our center's XR Lab we developed a collaborative tabletop application running on HL1, in which a "master" sends a 3D scene spatial anchor to the other participants which, in turn use it to synchronize their view with the master in such a way that all of them coherently place the same objects in respect to the physical world. This app utilizes the MS-NASA Holographic Sharing software and infrastructure.
With HL2, we tried to replicate such a behavior, but the MS-NASA software package is no longer available due to the changes to Unity (IL2CPP) and the previous APIs for anchor management have been removed and Azure Spatial Anchors were introduced, which require a subscription that is not feasible to our company's policy.
Our goal is only use spatial awareness for viewpoint sharing/synchronization, not for placing permanent anchors to points of interest.
The question is: is the Azure Spatial Anchor the right and only mean to pursue our purposes, or ordinary anchors are still available and usable? and, in the latter case, which API is devoted to it?
