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

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.

virtual float vtkShrinkPolyData::GetShrinkFactor   [virtual]
 

Get the fraction of shrink for each cell.

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.

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.

vtkShrinkPolyData* vtkShrinkPolyData::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkPolyDataSource.

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.

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.

virtual void vtkShrinkPolyData::SetShrinkFactor float    [virtual]
 

Set the fraction of shrink for each cell.
