Detailed Description

probe/interpolate data values in the interior, exterior or of the surface of a closed, manifold polyhedron

vtkProbePolyhedron 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 Source geometric structure is passed through the filter. The point attributes are computed at the Input point positions by interpolating into the source data. In this filter, the Source is always a closed, non-self-intersecting, polyhedral mesh. For example, we can compute data values on a plane (plane specified as Input) from a triangle mesh (e.g., output of marching cubes).

This filter can be used to resample data from a mesh onto a different dataset type. For example, a polyhedral mesh (vtkPolyData) 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 a mesh to produce x-y plots along that line or curve.

Warning

Note that cell data is not interpolated from the source. If you need cell data, you can always use vtkPointDataToCellData and/or vtkCellDataToPointData in various combinations.

Note that the filter interpolates from a mesh to points interior, exterior or on the surface of the mesh. This process is necessarily an approximation. Currently the approach of Mean Value Coordinates is used, but this filter may be extended in the future to use other methods.

virtual int vtkProbePolyhedron::RequestData ( vtkInformation *  , vtkInformationVector **  , vtkInformationVector *    )

protectedvirtual

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.

Reimplemented from vtkDataSetAlgorithm.

virtual int vtkProbePolyhedron::RequestInformation ( vtkInformation *  , vtkInformationVector **  , vtkInformationVector *    )

protectedvirtual

This is called within ProcessRequest when a request asks for Information. Typically an algorithm provides whatever lightweight information about its output that it can here without doing any lengthy computations. This happens in the first pass of the pipeline execution.

Reimplemented from vtkDataSetAlgorithm.

virtual int vtkProbePolyhedron::RequestUpdateExtent ( vtkInformation *  , vtkInformationVector **  , vtkInformationVector *    )

protectedvirtual

This is called within ProcessRequest when each filter in the pipeline decides what portion of its input is needed to create the portion of its output that the downstream filter asks for. This happens during the second pass in the pipeline execution process.

Reimplemented from vtkDataSetAlgorithm.
