Section: Visualization Toolkit Graphics Classes
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.
To create an instance of class vtkProbeFilter, simply invoke its constructor as follows
obj = vtkProbeFilter
obj
is an instance of the vtkProbeFilter class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkProbeFilter = obj.NewInstance ()
vtkProbeFilter = obj.SafeDownCast (vtkObject o)
obj.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 = obj.GetSource ()
- Specify the point locations used to probe input. Any geometry
can be used. Old style. Do not use unless for backwards compatibility.
obj.SetSourceConnection (vtkAlgorithmOutput algOutput)
- Specify the point locations used to probe input. Any geometry
can be used. New style. Equivalent to SetInputConnection(1, algOutput).
obj.SetSpatialMatch (int )
- 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.
int = obj.GetSpatialMatch ()
- 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.
obj.SpatialMatchOn ()
- 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.
obj.SpatialMatchOff ()
- 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.
vtkIdTypeArray = obj.GetValidPoints ()
- Get the list of point ids in the output that contain attribute data
interpolated from the source.
obj.SetValidPointMaskArrayName (string )
- Returns the name of the char array added to the output with values 1 for
valid points and 0 for invalid points.
Set to "vtkValidPointMask" by default.
string = obj.GetValidPointMaskArrayName ()
- Returns the name of the char array added to the output with values 1 for
valid points and 0 for invalid points.
Set to "vtkValidPointMask" by default.
