Hi,

Is it possible to show and interact with markup fiducials in VR?

This feature should be available within a few weeks (@cpinter is working on it).

Hi @lassoan , @cpinter  
I have tested the feature for displaying and interacting with markup fiducials in VR, but I still cannot interact with them. Is there a specific version or update I should install? Or are there particular settings that need to be enabled in the VR environment?

I use MetaQuest3, Slicer 5.6.2

Thanks in advance for your help!

Funding for VR/AR has been pretty scarce in the past years unfortunately, and the majority went toward OpenXR support to make SlicerVR (and other VTK based XR apps) future-proof, in the light of the older OpenVR backend being phased out.

There have been other funded initiatives (in-VR widget, collaborative feature, etc), probably the Kitware folks can give you more details, but as far as I know none of them are in an advanced state yet.

In particular the above feature that I was going to work on never actually got finished or integrated, as well as some other small projects I did in the spirit of proving that they can be done (like [this in-VR widget project](https://projectweek.na-mic.org/PW39_2023_Montreal/Projects/SlicerVRInteraction/)).

The current reality is that only such features and improvements are done in the XR topic that are directly funded by some driving use case.
