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. You can develop one from scratch, but if you are unfamiliar with the ParaView Python based scripting language, you can start from a working trace of a. The higher level lets you control the operation of ParaView, e.g., show data, set display properties, etc. In order to utilize ParaView in batch, you will first have to develop a Python script to perform all the necessary ParaView visualization operations.

Simply load the paraview.simple module from Python to get full access to all of ParaView’s large data visualization and analysis capabilities.

The lower level is where you can create or filter data with VTK. Seamless integration with Python began in ParaView version 3.0. 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.

I install paraview 5.6 on my Ubuntu 18.04 system and I want to write a python script to show a vtkUnstructuredGrid. ParaView scripts are easy to write, especially if you choose to simply record your work in the desktop application in the form of a python script.
