Detailed Description

Extracts outer (polygonal) surface.

vtkDataSetSurfaceFilter is a faster version of vtkGeometry filter, but it does not have an option to select bounds. It may use more memory than vtkGeometryFilter. It only has one option: whether to use triangle strips when the input type is structured.

Member Function Documentation

static vtkDataSetSurfaceFilter* vtkDataSetSurfaceFilter::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkPolyDataAlgorithm.

virtual const char* vtkDataSetSurfaceFilter::GetClassName ( ) [virtual]

Reimplemented from vtkPolyDataAlgorithm.

static int vtkDataSetSurfaceFilter::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkDataSetSurfaceFilter::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

static vtkDataSetSurfaceFilter* vtkDataSetSurfaceFilter::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

void vtkDataSetSurfaceFilter::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkDataSetSurfaceFilter::SetUseStrips ( int ) [virtual]

When input is structured data, this flag will generate faces with triangle strips. This should render faster and use less memory, but no cell data is copied. By default, UseStrips is Off.

virtual int vtkDataSetSurfaceFilter::GetUseStrips ( ) [virtual]

When input is structured data, this flag will generate faces with triangle strips. This should render faster and use less memory, but no cell data is copied. By default, UseStrips is Off.

virtual void vtkDataSetSurfaceFilter::UseStripsOn ( ) [virtual]

When input is structured data, this flag will generate faces with triangle strips. This should render faster and use less memory, but no cell data is copied. By default, UseStrips is Off.

virtual void vtkDataSetSurfaceFilter::UseStripsOff ( ) [virtual]

When input is structured data, this flag will generate faces with triangle strips. This should render faster and use less memory, but no cell data is copied. By default, UseStrips is Off.

virtual void vtkDataSetSurfaceFilter::SetPieceInvariant ( int ) [virtual]

If PieceInvariant is true, vtkDataSetSurfaceFilter requests 1 ghost level from input in order to remove internal surface that are between processes. False by default.

virtual int vtkDataSetSurfaceFilter::GetPieceInvariant ( ) [virtual]

If PieceInvariant is true, vtkDataSetSurfaceFilter requests 1 ghost level from input in order to remove internal surface that are between processes. False by default.

virtual void vtkDataSetSurfaceFilter::SetPassThroughCellIds ( int ) [virtual]

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.

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.

virtual void vtkDataSetSurfaceFilter::PassThroughCellIdsOn ( ) [virtual]

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.

virtual void vtkDataSetSurfaceFilter::PassThroughCellIdsOff ( ) [virtual]

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.

virtual void vtkDataSetSurfaceFilter::SetOriginalCellIdsName ( const char * ) [virtual]

If PassThroughCellIds or PassThroughPointIds is on, then these ivars control the name given to the field in which the ids are written into. If set to NULL, then vtkOriginalCellIds or vtkOriginalPointIds (the default) is used, respectively.

virtual const char* vtkDataSetSurfaceFilter::GetOriginalCellIdsName ( ) [inline, virtual]

If PassThroughCellIds or PassThroughPointIds is on, then these ivars control the name given to the field in which the ids are written into. If set to NULL, then vtkOriginalCellIds or vtkOriginalPointIds (the default) is used, respectively.

virtual void vtkDataSetSurfaceFilter::SetNonlinearSubdivisionLevel ( int ) [virtual]

If the input is an unstructured grid with nonlinear faces, this parameter determines how many times the face is subdivided into linear faces. If 0, the output is the equivalent of its linear couterpart (and the midpoints determining the nonlinear interpolation are discarded). If 1 (the default), the nonlinear face is triangulated based on the midpoints. If greater than 1, the triangulated pieces are recursively subdivided to reach the desired subdivision. Setting the value to greater than 1 may cause some point data to not be passed even if no nonlinear faces exist. This option has no effect if the input is not an unstructured grid.

virtual int vtkDataSetSurfaceFilter::GetNonlinearSubdivisionLevel ( ) [virtual]

If the input is an unstructured grid with nonlinear faces, this parameter determines how many times the face is subdivided into linear faces. If 0, the output is the equivalent of its linear couterpart (and the midpoints determining the nonlinear interpolation are discarded). If 1 (the default), the nonlinear face is triangulated based on the midpoints. If greater than 1, the triangulated pieces are recursively subdivided to reach the desired subdivision.
