Mayavi and mlab give a more high-level interface to VTK. By default, the reader assumes that you have a comma delimiter (i.e. txt file, you can directly open the data.
ParaView can read in delimited text files as tables, which is essentially what you have. Tvtk is a slightly more pythonic, low-level, python binding to VTK with a handful of really nice features (e.g. 1 Answer Sorted by: 5 The first step is reading your data into ParaView. (Either way, VTK is an excellent choice for this!) If you'd like to use a more "pythonic" interface to VTK, consider using mayavi/ tvtk/ mlab.

Reader.SetFileName('inputDataFiles/k_zCut.vtk') Here's the current version of the code I have (very similar to the one that successfully produces the surface plot): # import data I have looked at several examples on-line but none of them work for me (no errors are thrown, all I end up with is an empty render with just the background), all I have been able to do is a surface plot of the data (e.g.: here ).
#Paraview point data contour how to
Would you give me a hint on how to plot contour wisely I am suffering from this problem for almost 2 years. I'd rather stick with the vtk libraries than use something else, like Matplotlib, as I think they produce better visualisations in general. sharaborin (Eugene Sharaborin) September 4, 2020, 10:53am 1 Dear All, I am trying to draw a contour from Octree mesh, which is saved in an Unstructured Grid format (points in vertex, variables in cells. I am trying to produce a contour plot of said scalar to make it look somewhat like the attached picture made using ParaView. I have a set of data stored in a VTK file which represents a cut through a domain with scalar point data in an array.
