* @brief 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.
