Hello,
I have written a vtu file with a concave polygon (see the image" concave.png"
enclosed). I am surprised because the rendering in ParaView is inappropriate
(the mode is "Surface").I tried the same thing with a vtp file and it was the
same result. Moreover, when I try to visualize a vrml
GL doesn't handle concave polygons and subdividing concave polygons into
convex ones would add substantial overhead to the common case when none are
present, so VTK and therefore ParaView do not either.
See this thread where the issue was recently discussed for ideas about how
you might go about f
