Detailed Description

extracts points whose scalar value satisfies threshold criterion.

Date:
2000/12/10 20:08:55
Revision:
1.27

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

vtkThresholdPoints* vtkThresholdPoints::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkPolyDataSource.

virtual const char* vtkThresholdPoints::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataSetToPolyDataFilter.

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 vtkTypeMacro 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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataSetToPolyDataFilter.

vtkThresholdPoints* vtkThresholdPoints::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

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 vtkSource.

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]
 

void vtkThresholdPoints::operator= const vtkThresholdPoints &    [inline, protected]
 

Definition at line 86 of file vtkThresholdPoints.h.

void vtkThresholdPoints::Execute   [protected, virtual]
 

Reimplemented from vtkSource.

int vtkThresholdPoints::Lower float    s [inline, protected]
 

Definition at line 98 of file vtkThresholdPoints.h.

int vtkThresholdPoints::Upper float    s [inline, protected]
 

Definition at line 99 of file vtkThresholdPoints.h.

int vtkThresholdPoints::Between float    s [inline, protected]
 

Definition at line 100 of file vtkThresholdPoints.h.
