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.

High density spatial mapping

Hi all,
We have obtained the spatial mapping data for a cylindrical wall corner of about 2m x 1m as below:
How can we get a more dense and regular one, as below?:

@CurvSurf have you adjusted the TrianglesPerCubicMeter setting? There is an example in the Holograms 230 tutorial.
You could also use mesh post processing of some form to improve the results, but I think setting the TrianglesPerCubicMeter (unityengine.vr.wsa.surfacedata) to higher values than the default 500 might help get you closer to the sample image.

Hi HoloSheep,
Thanks for your advice.
We conclued the minimum inter-vertex distance of spatial mapping is about 4 mm. We might get a more dense point cloud. Then, we could recognize, detect, and measure smaller objects. With HoloLens and our middleware, the minimum size of measurable objects is about 1'.
For our job, automatic (real-time) data processing, a post-processing is categorically excluded.

Hi, it will be appreciate if you could point out where to conclue the minimum inter-vertex distance of spatial mapping

We have tested some values of TrianglesPerCubicMeter only to know the upperbound is ca. 2000. Then, the least minimum inter-vertex distance was ca. 4 mm empirically not theoretically.
