Detailed Description

shrink cells composing PolyData

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. Users should use the vtkTriangleFilter to triangulate meshes that contain triangle strips.

Member Function Documentation

vtkShrinkPolyData* vtkShrinkPolyData::New ( ) [static]

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

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

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 vtkTypeRevisionMacro 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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataToPolyDataFilter.

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

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 vtkPolyDataToPolyDataFilter.

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

Set the fraction of shrink for each cell.

virtual double vtkShrinkPolyData::GetShrinkFactor ( ) [virtual]

Get the fraction of shrink for each cell.

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

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