<div dir="ltr"><font face="tahoma" size="2">I want to generate and display data in the paraview GUI, all from the python shell tool. The vtk data is not generated from a reader or from inside a programmable source, but directly inside the paraview GUI shell
environment. I now want to connect the input of a filter to this polyData. Are there any interfacing functions to do this:
