[Paraview] Contours of integer array

[Schlottke-Lakemper, Michael]

Hi folks,

I would like to visualize an integer array of an unstructured dataset based on voxels, which contains MPI rank ids generated by a filter we use. To achieve this, I plan to somehow extract the “sharp” interfaces, similar to what the contour filter does, to obtain a visual representation of the domain decomposition. However, for the contour filter, I first have to call “Cell data to point data”, which smears out the previously sharp interfaces and causes connectivity problems of the resulting contours, as in some areas the domain decomposition features are very small.

Is there another way how I could extract these contours? Please note that I am not using vtkProcessId but rather an own integer array.

Thanks a lot in advance

Michael
