For example if I have a clip filter with type box, that I use to crop an image volume (unstructured grid).
If I use this clip filter as an input to a programmable filter, I only get the underlying vtk object, which is an unstrucutred grid. How can I obtain, the proxy propertes of the clip such as (Rotation, Position, etc.).
Generally, is there a way to query the proxy properites of inputs to programmable filters ?
