NAME
vtkProbeFilter - sample data values at specified point locations
SYNOPSIS
#include "/opt/vtk-c++/graphics/vtkProbeFilter.h"
class VTK_EXPORT vtkProbeFilter : public vtkDataSetToDataSetFilter
vtkProbeFilter();
static vtkProbeFilter *New() {return new vtkProbeFilter;};
const char *GetClassName() {return "vtkProbeFilter";};
void PrintSelf(ostream& os, vtkIndent indent);
void Update();
void SetSource(vtkDataSet*);
void SetSource(vtkDataSet& );
vtkDataSet *GetSource();
DESCRIPTION
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).
SUMMARY
void SetSource(vtkDataSet*)
void SetSource(vtkDataSet& )
Specify the point locations used to probe input. Any geometry can be used.
void Update()
Overload update method because execution can branch two ways (Input and Source). Also input and output are abstract.
