Paraview Sample Over Line

ParaView Support
1

Hi,

what is the equivalent vtk class used in the Paraview sample over line GUI? I would like to replicate it in python with the vtk wrappers

Internally, ParaView is using the custom vtkPVProbeLineFilter. I believe this is basically doing a vtkProbeFilter with a vtkLineSource but with a lot of special sauce to make it work in parallel.

Thanks a lot!
It seems that I was able to find it but I am unable to locate the equivalent of Sampling Pattern in the vtk python wrapper where only the following methods are exposed

Uh, weird. The class has SetPoint1 and SetPoint2 methods. I don’t know why those are not coming through in the python bindings. (They must work with the client/server bindings.)

Maybe someone who knows more about the wrapping could answer.
