Detailed Description

shrink cells composing an arbitrary data set.

Date:

2000/12/10 20:08:52

Revision:

1.39

vtkShrinkFilter shrinks cells composing an arbitrary data set towards their centroid. The centroid of a cell is computed as the average position of the cell points. Shrinking results in disconnecting the cells from one another. The output of this filter is of general dataset type vtkUnstructuredGrid.

Warning:

It is possible to turn cells inside out or cause self intersection in special cases.

Member Function Documentation

vtkShrinkFilter* vtkShrinkFilter::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkUnstructuredGridSource.

virtual const char* vtkShrinkFilter::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 vtkDataSetToUnstructuredGridFilter.

int vtkShrinkFilter::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 vtkDataSetToUnstructuredGridFilter.

virtual int vtkShrinkFilter::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 vtkDataSetToUnstructuredGridFilter.

vtkShrinkFilter* vtkShrinkFilter::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 vtkDataSetToUnstructuredGridFilter.

void vtkShrinkFilter::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.

virtual void vtkShrinkFilter::SetShrinkFactor (  float    )  [virtual]

Set the fraction of shrink for each cell.

virtual float vtkShrinkFilter::GetShrinkFactor (    )  [virtual]

Get the fraction of shrink for each cell.

void vtkShrinkFilter::operator= (  const vtkShrinkFilter &    )  [inline, protected]

Definition at line 84 of file vtkShrinkFilter.h.

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

Reimplemented from vtkSource.
