[Paraview] Paraview Programmable Source 3D Text

[Dr. Roman Grothausmann]

Dear Utkarsh,


Needing the same thing as Willi, I've created a paraview plugin written in C++ 
doing basically the same as Your script. Would it be possible to achieve 
something like vtkFollower does from within a c++ PV plugin such that the text 
always faces the camera? An other idea would be to use Python in the animation 
view to rotate the text as the camera orbits. This would be a workaround only 
for animations, which would suffice for me. Do You thing that should be possible 
if nothing else works?

Many thanks for looking into this.
Roman
