extract geometry from an unstructured grid
vtkUnstructuredGridGeometryFilter is a filter that extracts geometry (and associated data) from an unstructured grid. It differs from vtkGeometryFilter by not tessellating higher order faces: 2D faces of quadratic 3D cells will be quadratic. A quadratic edge is extracted as a quadratic edge. For that purpose, the output of this filter is an unstructured grid, not a polydata. Also, the face of a voxel is a pixel, not a quad. Geometry is obtained as follows: all 0D, 1D, and 2D cells are extracted. All 2D faces that are used by only one 3D cell (i.e., boundary faces) are extracted. It also is possible to specify conditions on point ids, cell ids, and on bounding box (referred to as "Extent") to control the extraction process.

If on, the output polygonal dataset will have a celldata array that holds the cell index of the original 3D cell that produced each output cell. This is useful for cell picking. The default is off to conserve memory. Note that PassThroughCellIds will be ignored if UseStrips is on, since in that case each tringle strip can represent more than on of the input cells.
