Detailed Description

Calculate functions of quality of the elements of a mesh.

vtkMeshQuality computes one or more functions of (geometric) quality for each 2-D and 3-D cell (triangle, quadrilateral, tetrahedron, pyramid, wedge, or hexahedron) of a mesh. These functions of quality are then averaged over the entire mesh. The minimum, average, maximum, and unbiased variance of quality for each type of cell is stored in the output mesh's FieldData. The FieldData arrays are named "Mesh Triangle Quality," "Mesh Quadrilateral Quality," "Mesh Tetrahedron Quality," "Mesh Pyramid Quality," "Mesh Wedge Quality," and "Mesh Hexahedron Quality." Each array has a single tuple with 5 components. The first 4 components are the quality statistics mentioned above; the final value is the number of cells of the given type. This final component makes aggregation of statistics for distributed mesh data possible.

By default, the per-cell quality is added to the mesh's cell data, in an array named "Quality." Cell types not supported by this filter will have an entry of 0. Use SaveCellQualityOff() to store only the final statistics.

This version of the filter written by Philippe Pebay and David Thompson overtakes an older version written by Leila Baghdadi, Hanif Ladak, and David Steinman at the Imaging Research Labs, Robarts Research Institute. That version only supported tetrahedral radius ratio. See the CompatibilityModeOn() member for information on how to make this filter behave like the previous implementation. For more information on the triangle quality functions of this class, cf. Pebay & Baker 2003, Analysis of triangle quality measures, Math Comp 72:244. For more information on the quadrangle quality functions of this class, cf. Pebay 2004, Planar Quadrangle Quality Measures, Eng Comp 20:2.

Warning: While more general than before, this class does not address many cell types, including triangle strips and fans in 2D (among others). Most quadrilateral quality functions are intended for planar quadrilaterals only. The minimal angle is not, strictly speaking, a quality function, but it is provided because of its usage by many authors.; This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.

◆ SetRatio()

virtual void vtkMeshQuality::SetRatio ( vtkTypeBool r )

inlinevirtual

These methods are deprecated.

Use Get/SetSaveCellQuality() instead.

Formerly, SetRatio could be used to disable computation of the tetrahedral radius ratio so that volume alone could be computed. Now, cell quality is always computed, but you may decide not to store the result for each cell. This allows average cell quality of a mesh to be calculated without requiring per-cell storage.
