[Paraview] Getting camera/view data in c++ filter

[Alex Rattner]

Hello,

I have been working on a c++ paraview filter and would like to modify 
output data based on the camera view direction/location. For example, I 
may want to highlight data closer to the viewer and remove far away 
data. Is it possible to access some of this information (like camera 
location, view direction, etc.) from a filter? I've seen some 
information on accessing this data in python, but I want to get it in a 
compiled c++ filter.

Thank you,
Alex
