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.

Is it possible to create SpatialUnderstanding playspace from stored mesh without scanning?

Hi, if I have a saved mesh from either SpatialMapping or SpatialUnderstanding, then is it possible if I load the mesh and create SpatialUnderstanding playspace from that mesh without requiring user to scan?

I tried with the HoloToolkit-Examples/SavingSpatialMeshes example and could save and load the mesh, but can't figure out how to automate the creation of playspace from the mesh.
Thank you.


  • Hey, @kevin0228ca

    If what you mean is substituting HoloLens's spatial data with your own (making HoloLens "think" that is its own data) then it is not possible. First of all because internal data and data fed as a mesh to your application are different with the latter being heavily simplified, baked and smoothened. It's a one way feed from device's sensors to your app.

    Thank you for the clarification.
    If I understand you correctly,
    by internal data, you mean the raw mesh generated by Hololens's depth sensor using Holotoolkit SpatialMapping,
    and by data fed as mesh to my app, you mean the smoothed mesh created by SpatialUnderstanding? (same as Holograms 230 chapter3?)

    What I have is either the raw mesh (saved from Hololens room scanning) and smoothed mesh (saved from the holotoolkit /SavingSpatialMeshes example).
    And was wondering if I could do either of the following from the loaded mesh.
    1. From a loaded raw mesh, perform smoothing and creating playspace.
    2. From a loaded smoothed mesh, perform creating playspace.
    both without scanning everytime I re run the app, as the environment I am using Hololens stays the same.
    From Young Conkers and Fragments, it seems to be possible to save and load playspace.
    Is that function provided in Holotoolkit, or do we have to implement our own?
    Thank you.
