Summary0010341: Negative Tetraheder Volumes in vtkMeshQuality
DescriptionSimilar to my previously reported bug, the vtkMeshQuality filter uses a formular that may produce negative volumes for Tetrahedra.

vtkMeshQuality does not use the vtkTetra::ComputeVolume() method, but rather the v_tet_vol() from verdict.

As before, the issue is resolved by adding an fabs(), see attached file with fix in line 1394
Steps To Reproduce
Additional InformationIn the verdict files themselves, v_tet_vol() is always used in conjuction with an fabs() when the actual volume is needed. It is probably only for checking orientation, that v_tet_vol() allows negative values itself.
