[Paraview-developers] using Immersive ParaView (zSpace) with pvospray (UNCLASSIFIED)

[Aashish Chaudhary]

Hi Simon,

Only thing I want to add is that tracker (head) sets the EyeTransformMatrix
using this api:
https://github.com/Kitware/VTK/blob/master/Rendering/Core/vtkCamera.cxx#L1788
which we added for tracking and some other related purposes and
SetModelTransformMatrix for wand navigation purposes. So if you are not
using these, you won't get head or wand tracking.

Best,
Aashish
