Spatial Mapping- Update and Cull

Hi Hololens Forum,

About to start developing in Unity, I have plenty of experience with spatial mapping from Tango.
Is it possible to save a mesh from a spatial map of a room, save it. Close the app, revisit the location and perform spatial mapping of the same region again and check for changes to the mesh to the previous mesh?

Essentially the programmatic plan would look like this:

Scan mesh
Save mesh
Reload mesh
Rescan mesh
Compare meshes
Show difference of two overlaid meshes

Not looking specifically for the code to do this, but if you know what references in the scripting I would be looking for it would really help me.

Thank you!
