I would like to know the difference between vtkMeshQuality and vtkCellSizeFilter for computing the volume of hexahedron cells. According to the VTK Documentation, vtkCellSizeFilter uses vtkMeshQuality for triangles, quadrilaterals, tetrahedrons and hexahedrons. However, in my test, both classes have produced different volumes.
vtkMeshQualify = 1.0 and vtkCellSizeFilter = 1.0 for:
vtkMeshQuality = 0.75 and vtkCellSizeFilter = 0.84 for:
vtkMeshQuality = 0.75 and vtkCellSizeFilter = 0.67 for:
