Detailed Description

sample data values at specified point locations

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). The cell data of the source data is copied to the output based on in which source cell each input point is. If an array of the same name exists both in source's point and cell data, only the one from the point data is probed.

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.

Warning: A critical algorithmic component of vtkProbeFilter is the manner in which it finds the cell containing a probe point. By default, the vtkDataSet::FindCell() method is used, which in turn uses a vtkPointLocator to perform an accelerated search. However, using a vtkPointLocator may fail to identify an enclosing cell in some cases. A more robust but slower approach is to use a vtkCellLocator to perform the the FindCell() operation (via specification of the CellLocatorPrototype). Finally, more advanced searches can be configured by specifying an instance of vtkFindCellStrategy. (Note: image data probing never uses a locator since finding a containing cell is a simple, fast operation. This specifying a vtkFindCellStrategy or cell locator prototype has no effect.); The vtkProbeFilter, once it finds the cell containing a query point, uses the cell's interpolation functions to perform the interpolate / compute the point attributes. Note that other interpolation processes with different kernels are available: vtkPointInterpolator and vtkSPHInterpolator. vtkPointInterpolator supports a variety of generalized kernels, while vtkSPHInterpolator supports a variety of SPH interpolation kernels.
