Greetings,
I have generated a simple vtk file that contains a single polygon. The
file is shown below.
# vtk DataFile Version 2.0
Output
ASCII
DATASET UNSTRUCTURED_GRID
POINTS 6 float
0.0048265 0.00753943 0

#end of file
After loading the file in paraview, the surface of the polygon is not
displayed correctly. It seems that an additional triangle is displayed.
However, the wireframe is displayed correctly. I have checked the order
of points and confirmed that the order is correct. I also multiplied the
coordinates by 100 but the problem persists.
If I add the first point of the polygon again, the surface is displayed
correctly. The modified lines read:
CELLS 1 8
7 0 1 2 3 4 5 0
Unfortunately, that fix does not work for other polygons that show the
same problem.
Is there something wrong with my vtk file?
Greetings,
Martin
