Summary0013338: Algorithm for polygon faceting for polyhedral finite elements
DescriptionThis is a request for a minor(?) alter in a VTK rendering algorithm.

Polyhedral finite elements are reaching a level of numerical maturity where
their use is likely to become widespread -- and correspondingly an
increased desire to display them in ParaView. For convex polygonal faces of
a polyhedron, the VTK algorithms work fine, and omitting the interior
triangle edges was a nice rendering improvement.

However, the discrete numerical algorithms that have emerged surprisingly
work for polyhedrons that have the "star property." Long story told short,
the attached ParaView figure in the right hand panel contains a polyhedral
finite element that has a non-planar, concave polygonal face. Numerically,
this polyhedral configuration works very well.

Would it be possible for rendering purposes, to create the polygon's
triangular sub-facets by starting with the polygon's vertex closest to the
average coordinate of the polygon's vertex nodal points? Maybe this
particular polygon vertex becomes a "common" vertex for all of the
sub-triangles?

Can you submit a test data set and script/procedure to reproduce the images shown in the figure?
Thanks

File added 2013-07-03 13:30 is a datum set for VTK bug 0013338 that you requested. It is a folder that contains a small EnSight-formatted datum set and a large *.pvsm file that will configure ParaView (3.98.1) at a starting point that displays the rendering problem addressed by the bug report. Unfortunately, the path for the datum set in the *.pvsm file references the location on my workstation where the 'p04' datum set resides.

Thank you for addressing this issue!!!
