<div dir="ltr">You can do just about anything you can do with a c++ filter (make internal filters, directly access input and output data sets) inside a programmable filter so a plugin shouldn't be a requirement to do what you want to do. In either case you will need to be familiar with the VTK API, python usually just makes the development task a bit quicker.<div>
