[Paraview] PythonProgrammableFilters Multiple Input Ports
Hi there,
I see an old thread here:
https://paraview.markmail.org/thread/z7cy73444s7fjadk about setting
multiple input ports for python programmable filters but I cannot get this
to work.
I want to declare multiple input ports in a ServerManagerConfiguration XML
plugin but I have been unable to successfully add more than one input port
to the vtkPythonProgrammableFilter.
I see that in
`paraview/ParaViewCore/ClientServerCore/Core/vtkPythonProgrammableFilter.h`
the following is declared:
/**
* Set the number of input ports
* This function is explicitly exposed to enable a
vtkClientServerInterpreter to call it
*/
void SetNumberOfInputPorts(int numberOfInputPorts) VTK_OVERRIDE
{
this->Superclass::SetNumberOfInputPorts(numberOfInputPorts);
}
This leads me to believe that the functionality is there, but how exactly
would I set the number of input ports from an XML plugin for a Programmable
Filter? I have tried the following with no luck:

[Paraview] Find the intersection point between a connectivity and a stream tracer
Dear Users, I need to find the intersection point between a connectivity surface (portion of a slice) and a stream tracer that runs through this. I have tried the IntersectFragments it doesn’t work with stream tracer. Someone of you have some suggestions?
