GMVReader plugin seals not watertight polyhedral cells on import
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The GMV file format allows for (nonstandard) cells to be described by their faces. One can define non-watertight cells this way. The attached sequence of GMV files stepwise defines a pyramid: the first file only contains the definition for the base, the second additionally defines one lateral face and so forth until the fifth file defines a watertight pyramid.
The GMVReader plugin currently imports the first and the last file of said sequence correctly (as quad and pyramid, respectively). Unfortunately, the remaining files, all of which merely define a partial pyramid, are incorrectly imported as watertight pyramids, too (because they are incorrectly mapped to VTK_CONVEX_POINT_SET instead of the appropriate VTK_POLYHEDRON).
