Detailed Description

extract boundary geometry from dataset (or convert data to polygonal type)

vtkGeometryFilter is a general-purpose filter to extract dataset boundary geometry, topology, and associated attribute data from any type of dataset. 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 a bounding box (referred to as "Extent") to control the extraction process. This point and cell id- and extent-based clipping is a powerful way to "see inside" datasets; however it may impact performance significantly.

This filter may also be used to convert any type of data to polygonal type. This is particularly useful for surface rendering. The conversion process may be less than satisfactory for some 3D datasets. For example, this filter will extract the outer surface of a volume or structured grid dataset (if point, cell, and extent clipping is disabled). (For structured data you may want to use vtkImageDataGeometryFilter, vtkStructuredGridGeometryFilter, vtkExtractUnstructuredGrid, vtkRectilinearGridGeometryFilter, or vtkExtractVOI.)

Another important feature of vtkGeometryFilter is that it preserves topological connectivity. This enables filters that depend on correct connectivity (e.g., vtkQuadricDecimation, vtkFeatureEdges, etc.) to operate properly . It is possible to label the output polydata with an originating cell (PassThroughCellIds) or point id (PassThroughPointIds). The output precision of created points (if they need to be created) can also be specified.

In some cases (especially for large unstructured grids) the vtkGeometryFilter can be slow. Consequently the filter has an optional "fast mode" that may execute significantly faster (>4-5x) than normal execution. The fast mode visits a subset of cells that may be on the boundary of the dataset (and skips interior cells which contribute nothing to the output). The set of subsetted cells is determined by inspecting the topological connectivity degree of each point (i.e., the number of unique cells using a particular point is that point's degree). With fast mode enabled, those cells connected to a point with degree <= Degree are visited. Note that this approach may miss some cells which contribute boundary faces–thus the output is an approximation to the normal execution of vtkGeometryFilter.

Finally, this filter takes an optional second, vtkPolyData input. This input represents a list of faces that are to be excluded from the output of vtkGeometryFilter.

Warning

While vtkGeometryFilter and vtkDataSetSurfaceFilter perform similar operations, there are important differences as follows:

vtkGeometryFilter preserves topological connectivity. vtkDataSetSurfaceFilter produces output primitives which may be disconnected from one another.
vtkGeometryFilter can generate output based on cell ids, point ids, and/or extent (bounding box) clipping. vtkDataSetSurfaceFilter strictly extracts the boundary surface of a dataset.
vtkGeometryFilter is much faster than vtkDataSetSurfaceFilter, especially for vtkUnstructuredGrids. As a result, vtkDataSetSurfaceFilter will delegate the processing of linear unstructured grids to vtkGeometryFilter.
vtkGeometryFilter can (currently) only handle linear cells. The filter will delegate to vtkDataSetSurfaceFilter for higher-order cells. (This is a historical artifact and may be rectified in the future.)

If point merging (MergingOff) is disabled, the filter will (if possible) use the input points and point attributes. This can result in a lot of unused points in the output, at some gain in filter performance. If enabled, point merging will generate only new points that are used by the output polydata cells.

This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.

Certain input dataset types (with implicit point representations) will always create new points (effectively performing a merge operation).

◆ MergingOff()

◆ SetOutputPointsPrecision()

void vtkGeometryFilter::SetOutputPointsPrecision ( int precision )

Set/get the desired precision for the output types.

See the documentation for the vtkAlgorithm::DesiredOutputPrecision enum for an explanation of the available precision settings. This only applies for data types where we create points (merging) as opposed to passing them from input to output, such as unstructured grids.

◆ SetFastMode()

virtual void vtkGeometryFilter::SetFastMode ( bool )

virtual

Turn on/off fast mode execution.

If enabled, fast mode typically runs much faster (2-3x) than the standard algorithm, however the output is an approximation to the correct result. Also, note that the FastMode depends on the data member Degree for its execution.

◆ GetFastMode()

virtual bool vtkGeometryFilter::GetFastMode ( )

virtual

Turn on/off fast mode execution.

virtual void vtkGeometryFilter::FastModeOff ( )

virtual

Turn on/off fast mode execution.

If enabled, fast mode typically runs much faster (2-3x) than the standard algorithm, however the output is an approximation to the correct result. Also, note that the FastMode depends on the data member Degree for its execution.

◆ SetDegree()

virtual void vtkGeometryFilter::SetDegree ( unsigned int )

virtual

If fast mode is enabled, then Degree controls which cells are visited.

Basically, any cell connected to a point with connectivity degree <= is visited and processed. Low degree points tend to be located on the boundary of datasets - thus attached cells frequently produce output boundary fragments.

◆ GetDegree()

virtual unsigned int vtkGeometryFilter::GetDegree ( )

virtual

If fast mode is enabled, then Degree controls which cells are visited.

Basically, any cell connected to a point with connectivity degree <= is visited and processed. Low degree points tend to be located on the boundary of datasets - thus attached cells frequently produce output boundary fragments.
