[Paraview-developers] Interacting with our data and an HTC Vive

[Nikhil Shetty]

Hi Ken,

Please let me know if you would like contributions to the work you mention
to improve widgets and interactions with OpenVR/VTK/PV. If you could point
me to the branch on GitLab then I can take a play with it, give feedback
and contribute.

Regards
Nikhil
