Detailed Description

shrink cells composing PolyData.

Date:

2000/12/10 20:08:52

Revision:

1.43

vtkShrinkPolyData shrinks cells composing a polygonal dataset (e.g., vertices, lines, polygons, and triangle strips) 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 dataset type of this filter is polygonal data.

During execution the filter passes its input cell data to its output. Point data attributes are copied to the points created during the shrinking process.

Warning:

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

Member Function Documentation

vtkShrinkPolyData* vtkShrinkPolyData::New (    )  [static]

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

virtual const char* vtkShrinkPolyData::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 vtkPolyDataToPolyDataFilter.

int vtkShrinkPolyData::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 vtkPolyDataToPolyDataFilter.

virtual int vtkShrinkPolyData::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 vtkPolyDataToPolyDataFilter.

vtkShrinkPolyData* vtkShrinkPolyData::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 vtkPolyDataToPolyDataFilter.

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

Set the fraction of shrink for each cell.

virtual float vtkShrinkPolyData::GetShrinkFactor (    )  [virtual]

Get the fraction of shrink for each cell.

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

Definition at line 88 of file vtkShrinkPolyData.h.

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

Reimplemented from vtkSource.
