The quantities should be created by a simple function interface, and would then exist as variables in the Python interpreter for further calculation. Examples of such calculations are the average values of results variables for defined regions of the mesh, and integration of results variables over individual elements of the mesh. The scripting command language supports calculator type operations in addition to visualization operations.The new command language is similar to a macro language that encapsulates a large number of low level Python commands. Users can still access the more featured and flexible underlying Python interface that exists currently in ParaView.Old scripts can be appended to new scripts or used like subroutines. The scripting commands are modular and extensible. Use of these scripting commands does not require a deep understanding of Python programming or the implementation specifics of ParaView and VTK. The documentation is available in varying levels of detail from the Python interpreter, the ParaView program help system, and from the ParaView webpage. The scripting commands are simple, uniform, and documented. The modified ParaView scripting language is command based and in Python. The progress of the new API work and open issues are at Scripting Changes Progress.ĭesired Changes and Additions to ParaView Scripting Python based The XML output for ParaView state files is not easily read or edited by users. ParaView uses XML files to record and load the state of the ParaView GUI client. In addition, the Python scripting interface is not well documented, which forces users to consult the C++ implementation details of the underlying implementation classes to fully use ParaView Python scripting. This power and flexibility also greatly limits the number of ParaView users who can spend the time to master and apply ParaView Python scripting for their domain specific problem. The current ParaView Python scripting language is flexible and powerful in that it allows almost all classes defined in VTK and ParaView to be accessed from Python. ![]() Users can build VTK data pipelines using Python to drive ParaView from both inside and outside of the ParaView GUI client. A majority of ParaView implementation classes are "wrapped", making them accessible from a Python interpreter. ![]() ParaView currently uses Python as its scripting language. The interested parties are Sandia National Laboratories and Kitware Incorporated. ![]() The purpose of this Wikipage is to capture the ideas and observations concerning the design and implementation of a revised scripting language for ParaView.
