Detailed Description

sample data values at specified point locations

vtkProbeFilter is a filter that computes point attributes (e.g., scalars, vectors, etc.) at specified point positions. The filter has two inputs: the Input and Source. The Input geometric structure is passed through the filter. The point attributes are computed at the Input point positions by interpolating into the source data. For example, we can compute data values on a plane (plane specified as Input) from a volume (Source).

This filter can be used to resample data, or convert one dataset form into another. For example, an unstructured grid (vtkUnstructuredGrid) can be probed with a volume (three-dimensional vtkImageData), and then volume rendering techniques can be used to visualize the results. Another example: a line or curve can be used to probe data to produce x-y plots along that line or curve.

Member Function Documentation

static vtkProbeFilter* vtkProbeFilter::New (   )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

virtual const char* vtkProbeFilter::GetClassName (   )  [virtual]

Reimplemented from vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

static int vtkProbeFilter::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 vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

virtual int vtkProbeFilter::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 vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

static vtkProbeFilter* vtkProbeFilter::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

void vtkProbeFilter::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 vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

void vtkProbeFilter::SetSource (  vtkDataObject *  source  )

Specify the point locations used to probe input. Any geometry can be used. Old style. Do not use unless for backwards compatibility.

vtkDataObject* vtkProbeFilter::GetSource (   )

void vtkProbeFilter::SetSourceConnection (  vtkAlgorithmOutput *  algOutput  )

Specify the point locations used to probe input. Any geometry can be used. New style. Equivalent to SetInputConnection(1, algOutput).

virtual void vtkProbeFilter::SetSpatialMatch (  int   )  [virtual]

This flag is used only when a piece is requested to update. By default the flag is off. Because no spatial correspondence between input pieces and source pieces is known, all of the source has to be requested no matter what piece of the output is requested. When there is a spatial correspondence, the user/application can set this flag. This hint allows the breakup of the probe operation to be much more efficient. When piece m of n is requested for update by the user, then only n of m needs to be requested of the source.

virtual int vtkProbeFilter::GetSpatialMatch (   )  [virtual]

Specify the point locations used to probe input. Any geometry can be used. New style. Equivalent to SetInputConnection(1, algOutput).

virtual void vtkProbeFilter::SpatialMatchOn (   )  [virtual]

Specify the point locations used to probe input. Any geometry can be used. New style. Equivalent to SetInputConnection(1, algOutput).

virtual void vtkProbeFilter::SpatialMatchOff (   )  [virtual]

Specify the point locations used to probe input. Any geometry can be used. New style. Equivalent to SetInputConnection(1, algOutput).

virtual vtkIdTypeArray* vtkProbeFilter::GetValidPoints (   )  [virtual]

Get the list of point ids in the output that contain attribute data interpolated from the source.

virtual int vtkProbeFilter::RequestData (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [protected, virtual]

This is called by the superclass. This is the method you should override. Reimplemented from vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

virtual int vtkProbeFilter::RequestInformation (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [protected, virtual]

This is called by the superclass. This is the method you should override. Reimplemented from vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

virtual int vtkProbeFilter::RequestUpdateExtent (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [protected, virtual]

This is called by the superclass. This is the method you should override. Reimplemented from vtkDataSetAlgorithm. Reimplemented in vtkPProbeFilter.

void vtkProbeFilter::Probe (  vtkDataSet *  input, vtkDataSet *  source, vtkDataSet *  output )  [protected]
