Detailed Description

Extracts outer (polygonal) surface.

Date:

2001/11/13 14:13:49

Revision:

1.6

vtkDataSetSurfaceFilter is a fast 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

vtkDataSetSurfaceFilter* vtkDataSetSurfaceFilter::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkPolyDataSource. Reimplemented in vtkPVGeometryFilter.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToPolyDataFilter. Reimplemented in vtkPVGeometryFilter.

int vtkDataSetSurfaceFilter::IsTypeOf (  const char *    type )  [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 vtkDataSetToPolyDataFilter. Reimplemented in vtkPVGeometryFilter.

virtual int vtkDataSetSurfaceFilter::IsA (  const char *    type )  [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 vtkDataSetToPolyDataFilter. Reimplemented in vtkPVGeometryFilter.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToPolyDataFilter. Reimplemented in vtkPVGeometryFilter.

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 vtkSource. Reimplemented in vtkPVGeometryFilter.

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.

void vtkDataSetSurfaceFilter::ComputeInputUpdateExtents (  vtkDataObject *    output )  [protected, virtual]

Do not let images return more than requested. Reimplemented from vtkDataSetToPolyDataFilter.

void vtkDataSetSurfaceFilter::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource. Reimplemented in vtkPVGeometryFilter.

void vtkDataSetSurfaceFilter::StructuredExecute (  vtkDataSet *    input, int *    ext )  [protected]

void vtkDataSetSurfaceFilter::UnstructuredGridExecute (    )  [protected]

void vtkDataSetSurfaceFilter::DataSetExecute (    )  [protected]

void vtkDataSetSurfaceFilter::ExecuteInformation (    )  [protected, virtual]

Reimplemented from vtkSource.
