Detailed Description

extracts points whose scalar value satisfies threshold criterion

Revision
1.33

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.

Member Function Documentation

static vtkThresholdPoints* vtkThresholdPoints::New  )  [static]
 

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkThresholdPoints::GetClassName  )  [virtual]
 

Reimplemented from vtkDataSetToPolyDataFilter.

static int vtkThresholdPoints::IsTypeOf const char *  type  )  [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 vtkDataSetToPolyDataFilter.

virtual int vtkThresholdPoints::IsA const char *  type  )  [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.

Reimplemented from vtkDataSetToPolyDataFilter.

static vtkThresholdPoints* vtkThresholdPoints::SafeDownCast vtkObject o  )  [static]
 

Reimplemented from vtkDataSetToPolyDataFilter.

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 vtkDataSetToPolyDataFilter.

void vtkThresholdPoints::ThresholdByLower float  lower  ) 
 

Criterion is cells whose scalars are less than lower threshold.

void vtkThresholdPoints::ThresholdByUpper float  upper  ) 
 

Criterion is cells whose scalars are less than upper threshold.

void vtkThresholdPoints::ThresholdBetween float  lower,
float  upper
 

Criterion is cells whose scalars are between lower and upper thresholds.

virtual float vtkThresholdPoints::GetUpperThreshold  )  [virtual]
 

Get the upper and lower thresholds.

virtual float vtkThresholdPoints::GetLowerThreshold  )  [virtual]
 

Get the upper and lower thresholds.

void vtkThresholdPoints::Execute  )  [protected, virtual]
 

This method is the old style execute method

Reimplemented from vtkSource.
