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.
Mapping large rooms
I'm trying to use the information recorded in Hololens to build a 3D model of a large floor plan (this could be an office, airport ... etc).
When I try to dump the .obj file from the device using the online portal (as in the pic)
I always find that some parts that I have already visited are missing. More specifically, I noticed that the further the mappings from my current position the less likely that it will appear in the dumped .obj file, but when I go back to somewhere near the old mappings the old mappings appear again in the .obj file without even revisiting them again, which makes me suspect that HL saves a full copy of everything it knows about the physical world on disk and only load a small portion of it to memory at a specific moment. Of course, this is just an observation and might be totally wrong.
I'm mainly interested in the full mapping if it exists on disk or If my assumption is wrong, is it possible to extract a 3D model of a big floor using HL in some other way without stitching multiple .obj files?
