Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

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!
