This module can be loaded from any python interpreter as long as the necessary files are in PYTHONPATH. To start interacting with the Server Manager, you have to load the "simple" module. You may also visit the Python recipes page for some examples. This document is a short introduction to ParaView's Python interface. Note: Server Manager is a library that is designed to make it easy to build distributed client-server applications. Using Python, users and developers can gain access to the ParaView engine called Server Manager. This support is available as part of the ParaView client (paraview), an MPI-enabled batch application (pvbatch), the ParaView python client (pvpython), or any other Python-enabled application. ParaView offers rich scripting support through Python. 5.6 Writing Data Files (ParaView 3.9 or later).So change that line to cell = np.array(, ], dtype=np. The first entry in a cell definition needs to be the number of points defining the cell. There is also a problem with how you are defining cells. (Caveat: this only works when you are running in built-in server mode because of GetClientSideObject(), which is fairly common). All it does is take a dataset and pass that to any downstream filters that request it. This creates a ParaView proxy ( TrivialProducer) that is a proxy for a simple VTK data source called a vtkTrivialProducer. Tp.GetClientSideObject().SetOutput(uGrid) # create a trivial producer to bridge between the VTK object and ParaView To get it to a place where ParaView can use it add the following: # how to put uGrid into the following codes In your original example, you are creating an unstructured grid in VTK just fine. What you are missing is a bridge between the two levels in your script. The higher level lets you control the operation of ParaView, e.g., show data, set display properties, etc. The lower level is where you can create or filter data with VTK. The key thing to understand is that there are two levels of Python scripting available in ParaView. TypeError: Show argument 1: method requires a vtkSMSourceProxy, a vtkPythonAlgorithm was provided.
