sample data values at specified point locations 
<p>
<a class="el" href="a00603.html" title="sample data values at specified point locations">vtkGenericProbeFilter</a> 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).<p>
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 <a class="el" href="a00751.html" title="topologically and geometrically regular array of data">vtkImageData</a>), 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.<p>
This filter has been implemented to operate on generic datasets, rather than the typical <a class="el" href="a00374.html" title="abstract class to specify dataset behavior">vtkDataSet</a> (and subclasses). <a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> is a more complex cousin of <a class="el" href="a00374.html" title="abstract class to specify dataset behavior">vtkDataSet</a>, typically consisting of nonlinear, higher-order cells. To process this type of data, generic cells are automatically tessellated into linear cells prior to isocontouring.<p>
