extract data based on geometric connectivity
vtkConnectivityFilter is a filter that extracts cells that share common points and/or meet other connectivity criterion. (Cells that share vertices and meet other connectivity criterion such as scalar range are known as a region.) The filter works in one of six ways: 1) extract the largest connected region in the dataset; 2) extract specified region numbers; 3) extract all regions sharing specified point ids; 4) extract all regions sharing specified cell ids; 5) extract the region closest to the specified point; or 6) extract all regions (used to color the data by region).
vtkConnectivityFilter is generalized to handle any type of input dataset. If the input to this filter is a vtkPolyData, the output will be a vtkPolyData. For all other input types, it generates output data of type vtkUnstructuredGrid. Note that the only Get*Output() methods that will return a non-null pointer are GetUnstructuredGridOutput() and GetPolyDataOutput() when the output of the filter is a vtkUnstructuredGrid or vtkPolyData, respectively.
The behavior of vtkConnectivityFilter can be modified by turning on the boolean ivar ScalarConnectivity. If this flag is on, the connectivity algorithm is modified so that cells are considered connected only if 1) they are geometrically connected (share a point) and 2) the scalar values of one of the cell's points falls in the scalar range specified. This use of ScalarConnectivity is particularly useful for volume datasets: it can be used as a simple "connected segmentation" algorithm. For example, by using a seed voxel (i.e., cell) on a known anatomical structure, connectivity will pull out all voxels "containing" the anatomical structure. These voxels can then be contoured or processed by other visualization filters.
If the extraction mode is set to all regions and ColorRegions is enabled, The RegionIds are assigned to each region by the order in which the region was processed and has no other significance with respect to the size of or number of cells.
