a simple class to control print indentation
Definition vtkIndent.h:40
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
extracts points whose scalar value satisfies threshold criterion
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ThresholdByLower(double lower)
Criterion is cells whose scalars are less or equal to lower threshold.
~vtkThresholdPoints() override=default
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
int(vtkThresholdPoints::* ThresholdFunction)(double s)
void ThresholdBetween(double lower, double upper)
Criterion is cells whose scalars are between lower and upper thresholds (inclusive of the end values)...
static vtkThresholdPoints * New()
void ThresholdByUpper(double upper)
Criterion is cells whose scalars are greater or equal to upper threshold.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
