[Paraview] Displaying a flat polygon with multiple vertices

[Burlen Loring]

Hi David,

I think that the issue is that the polygon you constructed is not 
convex. Figure 19-20 in VTK users guide is misleading because the 
example of VTK_POLYGON shows a non-convex polygon which as you found out 
doesn't work.
