Detailed Description

sample data values at specified point locations

vtkGenericProbeFilter 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, a generic dataset 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.

This filter has been implemented to operate on generic datasets, rather than the typical vtkDataSet (and subclasses). vtkGenericDataSet is a more complex cousin of vtkDataSet, typically consisting of nonlinear, higher-order cells. To process this type of data, generic cells are automatically tessellated into linear cells prior to isocontouring.

Member Function Documentation

static vtkGenericProbeFilter* vtkGenericProbeFilter::New  )  [static]

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

Reimplemented from vtkAlgorithm.

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

Reimplemented from vtkDataSetToDataSetFilter.

static int vtkGenericProbeFilter::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 vtkDataSetToDataSetFilter.

virtual int vtkGenericProbeFilter::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 vtkDataSetToDataSetFilter.

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

Reimplemented from vtkDataSetToDataSetFilter.

void vtkGenericProbeFilter::PrintSelf ostream &  os,
vtkIndent  indent

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 vtkDataSetToDataSetFilter.

void vtkGenericProbeFilter::SetSource vtkGenericDataSet source  ) 

Specify the point locations used to probe input. A generic dataset type is assumed.

vtkGenericDataSet* vtkGenericProbeFilter::GetSource  ) 

virtual vtkIdTypeArray* vtkGenericProbeFilter::GetValidPoints  )  [virtual]

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

virtual void vtkGenericProbeFilter::Execute  )  [protected, virtual]

This method is the old style execute method

Reimplemented from vtkSource.
