Detailed Description

Calculate functions of quality of the elements of a mesh.

vtkCellQuality computes one or more functions of (geometric) quality for each cell of a mesh. The per-cell quality is added to the mesh's cell data, in an array named "CellQuality." Cell types not supported by this filter or undefined quality of supported cell types will have an entry of -1.

Warning: 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.

Methods invoked by print to print information about the object including superclasses.

Reimplemented from vtkDataSetAlgorithm.

◆ IsA()

virtual vtkTypeBool vtkCellQuality::IsA ( const char * name )

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

◆ SetQualityMeasure()

virtual void vtkCellQuality::SetQualityMeasure ( int )

virtual

Set/Get the particular estimator used to function the quality of all supported geometries.

For qualities that are not defined for certain geometries, later program logic ensures that CellQualityNone static function will be used so that a predefined value is returned for the request. There is no default value for this call and valid values include all possible qualities supported by this class.

◆ GetQualityMeasure()

virtual int vtkCellQuality::GetQualityMeasure ( )

virtual

Set/Get the particular estimator used to function the quality of all supported geometries.

For qualities that are not defined for certain geometries, later program logic ensures that CellQualityNone static function will be used so that a predefined value is returned for the request. There is no default value for this call and valid values include all possible qualities supported by this class.

This is called within ProcessRequest when a request asks the algorithm to do its work.

This is the method you should override to do whatever the algorithm is designed to do. This happens during the final pass in the pipeline execution process.

A function called by some VERDICT triangle quality functions to test for inverted triangles.

VERDICT only accepts plain function pointers which means the follow function and member must be static. Unfortunately, this makes the use of this part not thread safe.
