[Paraview-developers] Filter Plugin

[Frank TT]

Hi,


I want to write my own filter plugin.

I'm i little confused, how to do. I read already the 'how to'[1], had a
look at the example plugins and the PV plugins and searched the ML
archive.

I'm trying to implement a algorithm that works on loaded volume data and
creates a suface data. What I wrote below [2].

Now I'm not sure how to access the marked data set from the pipeline
browser, manipulate the data and then write the new output (with load
and display).

Can anyone give me some hints? Or is there a plugin I have to see?


Greetings
Frank
