Detailed Description

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.

Warning
When vtkUnstructuredGridGeometryFilter extracts cells (or boundaries of cells) it will (by default) merge duplicate vertices. This may cause problems in some cases. Turn merging off to prevent this from occurring.
