static bool CanFullyProcessDataObject(vtkDataObject *object, const char *scalarArrayName)
Returns true if the data object passed in is fully supported by this filter, i.e.,...

Inform the user as to whether large ids were used during filter execution.
static vtkContour3DLinearGrid * New()
Standard methods for construction, type info, and printing.
vtkMTimeType GetMTime() override
Overloaded GetMTime() because of delegation to the internal vtkContourValues class.
double * GetValues()
Get a pointer to an array of contour values.
virtual void SetScalarTree(vtkScalarTree *)
Specify the scalar tree to use.
int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector) override

int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
vtkIdType GetNumberOfContours()
Get the number of contours in the list of contour values.
int RequestDataObject(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector) override
This is called by the superclass.
