The Python Calculator allows a user to apply calculations that are available in Python. These are the Python Calculator and the Programmable Filter. It was certainly hard to pick up off-the-shelf. ParaView has two filters that give a user access to python math functions as well as the underlying VTK library. ParaView is a powerful open-source visualisation tool, but our initial impressions of developing for it in Python suggest this is trickier than we'd like. However, as far as we could ascertain, it is not possible to create a dialog box from a Python script embedded in ParaView - which defeated our initial requirement before we were off the ground!

We learned the above by joining the mailing lists - and we'd recommend this for anyone planning to develop plugins or scripts to work with ParaView.įollowing discussions on the list and the wiki for a while led us to the conclusion that to create a ParaView Reader implemented in Python one should embed the code in a “ programmable filter”. This second one proved most useful, but hard to find. On the subject of wikis, there are two main ParaView wikis:, used by most users and , where most development information is placed. Further, there is out-of-date information on the wiki - some examples which we downloaded would not load because the package structure of the Python code incorporated into ParaView had changed, for instance. We searched the ParaView website for information on this with limited success: whilst there was material that appeared to be relevant, an overview to help synthesise this information into a detailed solution appeared to be lacking. Our main task was to create the ParaView Reader in Python. Animate polydata using programmable filter is close but the author takes a constant multiplied by the time in transform.

Edits were needed to the makefile to point it at the version of Python we wanted. The transform filter through a python script is probably the way to go but I am at a loss how to reference the TableToPoin inputs. Please use the history if you want to access the old version of this document.

Since our starting point required Python 2.5.5, we had no option but to download the ParaView source and build a new version.Ĭompiling ParaView is fine, if a rather lengthy process. ParaView/Users Guide/Python Programmable Filter - KitwarePublic ParaView/Users Guide/Python Programmable Filter < ParaView PAGE DELETED The Users Guide has been moved from the Wiki to The ParaView Guide. Initially we used the downloadable binary one initial niggle we encountered was that the path to the Python version it used (2.5.1) is hard coded in the binary. We worked with ParaView 3.8.0 (version 3.8.1 is now out).

One main requirement was to enable the user to be able to select input files via a dialog. While working with the Culham Centre for Fusion Energy on streamlining the visualisation of output from the GS2 fusion simulation suite we've had a few tussles with the ParaView visualisation tool.īeginning with an existing Python program that post-processes GS2 output into a format that can be read by ParaView, our initial goal was to modify the program so that it could be use as a component (a Reader) in a ParaView/VTK pipeline (ParaView is built on VTK).
