Hi Sebastien,
Thank you very much for the advice. I was able to incorporate the
implicit_function plane property using this xml as a guide.

Hi Alex,
I don't fully understand what you mean but in ParaView the way clip or

just paste you both clip and slice proxy definition for convenience.

Hello,
I am trying to develop a compiled paraview filter that takes an input
plane/direction vector (like the clip or slice filters). Does anyone know of
example code that shows how to incorporate the ImplicitPlane widget into the
server manager xml. In particular, I want a way to get the Camera Normal. Is
this possible?
Thanks,
Alex
