#include <vtkThresholdPoints.h>
vtkThresholdPoints is a filter that extracts points from a dataset that satisfy a threshold criterion. The criterion can take three forms: 1) greater than a particular value; 2) less than a particular value; or 3) between a particular value. The output of the filter is polygonal data.

static vtkThresholdPoints* vtkThresholdPoints::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkPolyDataAlgorithm.
virtual const char* vtkThresholdPoints::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkPolyDataAlgorithm.
static int vtkThresholdPoints::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataAlgorithm.
virtual int vtkThresholdPoints::IsA | ( | const char * | name | ) | [virtual] |
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 vtkTypeRevisionMacro found in vtkSetGet.h.

void vtkThresholdPoints::PrintSelf | ( | ostream & | os, | |
vtkIndent | indent | |||
) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkPolyDataAlgorithm.
void vtkThresholdPoints::ThresholdByLower | ( | double | lower | ) |
Criterion is cells whose scalars are less or equal to lower threshold.
void vtkThresholdPoints::ThresholdByUpper | ( | double | upper | ) |
Criterion is cells whose scalars are greater or equal to upper threshold.
void vtkThresholdPoints::ThresholdBetween | ( | double | lower, | |
double | upper | |||
) |
Criterion is cells whose scalars are between lower and upper thresholds (inclusive of the end values).
virtual void vtkThresholdPoints::SetUpperThreshold | ( | double | ) | [virtual] |
Set/Get the upper threshold.
virtual double vtkThresholdPoints::GetUpperThreshold | ( | ) | [virtual] |
Set/Get the upper threshold.
virtual void vtkThresholdPoints::SetLowerThreshold | ( | double | ) | [virtual] |
Set/Get the lower threshold.
virtual double vtkThresholdPoints::GetLowerThreshold | ( | ) | [virtual] |
Set/Get the lower threshold.
virtual int vtkThresholdPoints::RequestData | ( | vtkInformation * | request, | |
vtkInformationVector ** | inputVector, | |||

) | [protected, virtual] |
This is called by the superclass. This is the method you should override.
Reimplemented from vtkPolyDataAlgorithm.
virtual int vtkThresholdPoints::FillInputPortInformation | ( | int | port, | |
vtkInformation * | info | |||
) | [protected, virtual] |
Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.
