// .NAME vtkGenericProbeFilter - sample data values at specified point locations
|
|
// .SECTION Description
|
|
// 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.
