vtkBandedDataContourFilter does not fill contours properly
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Download all attached files into a directory Run ~/build/VTK/bin/vtkpython banded-contour.py This generates a file band-4.vtp which is the band between contours at 40 and 50.
Load banded-contour.pvsm in ParaView. This shows contours at 40 and 50 and the band generated at the previous step.
The bug is that the band is not the proper fill of the space between the two contours. See also the attached images which shows the contours and then the contours and the band.
The following behavior is actually the bug we've seen in UVCDAT.
If you generate bands for all intervals (0,10), (10,20), ... (90,100) and load those in ParaView, the generated image has missing triangles. See contours-all.png To try this:
- Execute ~/build/VTK/bin/vtkpython banded-contour-all.py
- Load in ParaView banded-contour-all.pvsm You'll see an image with missing triangles.
