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.

Hologram groups and drift

edited October 2016 in Questions And Answers

This is similar to a question asked previously, but the answer didn't seem to help me much.

I am building a custom measurement tool of sorts. I have n number of points with a LineRenderer connecting them all.

The end goal here is actually determine the accuracy, we are hoping for sub millimeter accuracy within 3 meters. This isn't that important other than I want to point out that my drift is not serious, but certainly outside of our error tolerance.

Aside from the drifting itself, one problem I am facing is that the line doesn't drift with the points making things look pretty crappy, I might be able to deal with more drift if it wasn't as visually obvious.

I see the paragraph below from the documentation and I have tried a myriad of things, but it seems like I am missing some fundamental concept.

_Group holograms that should form a rigid cluster
Multiple holograms can share the same spatial anchor if the app expects those holograms to maintain fixed relationships to one another.



  • while I am still interested in how to group these together, I've found a work around for the line drifting separately by redrawing it every frame.

  • Hi RobAllen, have you succeed in obtaining sub millimeter accuracy with hololens?
