[Paraview-developers] Headtracking and camera settings

[Jean-Noël Chiganne]

Thanks for your answer Nikhil ! So it should be a solution to "manually"
disable camera control in the client and just manipulate view through
headtracking->projectionMatrix.

Here is the pvx file. It's not for an entire CAVE actually, I just used the
front screen and ground screen for my tests.

All the best,

Jean-Noël
