Greetings!  
I can successfully load a dataset (.vti) in ParaView but I’d like to know what underlying reader, mapper etc is used because I want to replicate the same pipeline in vtk python wrapper as far as basic visualization goes.  
Any pointers appreciated!

Thank you 🙂

The datapart of the pipeline is quite straightforward, reader -\> filter -\> filter  
The visualization part of the pipeline is much more complex. I would suggest just using a standard surface mapper unless you have specific needs.
