vtkExtractUnstructuredGrid is a general-purpose filter to extract geometry (and associated data) from an unstructured grid dataset. The extraction process is controlled by specifying a range of point ids, cell ids, or a bounding box (referred to as "Extent"). Those cells lying within these regions are sent to the output. The user has the choice of merging coincident points (Merging is on) or using the original point set (Merging is off).
-
Warning:
-
If merging is off, the input points are copied through to the output. This means unused points may be present in the output data. If merging is on, then coincident points with different point attribute values are merged.
