Hello everyone.

The Mixed Reality Forums here are no longer being used or maintained.

There are a few other places we would like to direct you to for support, both from Microsoft and from the community.

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.

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, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

And always feel free to hit us up on Twitter @MxdRealityDev.

System's Spaces vs in-app mapping


It seems the system needs to know where you are located (spaces) that's why I don't really understand why my app needs to scan the room itself instead of just using the current system space.

A related question : Tutorials are all showing how to save the result of the mapping into your desktop computer (for later use in unity) but the end-user will not have Unity, why don't you add tutorials to save/load these mapping results from the Hololens device itself ???


Best Answer


  • The app doesn't actually need to scan the room. The spatial mapping features will pull in whatever data the currently loaded space has available (within the bounding volume). The spatial understanding feature does require that you look, but this is an artificial requirement, and it could be rewritten to not have this behavior.

    The purpose of helping developers get their spatial map into Unity is to all you to iterate in the unity editor with a sense of real world scale and to enable you to experiment with processing / shading the spatial mapping mesh. It's not a feature end users would need to use.

    We developers will be understanding HoloLens a little more everydays. Please provide us developers with the real-time raw depth data stream, the raw data used for updating the spatial mapping!

    • Intel RealSense: max 60 fps raw depth data stream
    • Google Tango: about 5 fps raw depth data stream.
    • MS HoloLens: no raw depth data stream, only spatial mapping!
  • Hi @CurvSurf,
    Since I came from Kinect, I can understand why you would like access to the raw depth streams, but unfortunately I do not have power to grant your request :)

    Could you please file a feature request using the 'Feedback Hub' on the HoloLens?
