| Summary | 0010341: Negative Tetraheder Volumes in vtkMeshQuality |
| Description | Similar 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 |
| Additional Information | In 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. |
