// .NAME vtkShrinkPolyData - shrink cells composing PolyData
|
||
|
|
// .SECTION Description
|
||
|
|
// 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.
|
||
|
|
|
||
|
|
// .SECTION Caveats
|
||
|
|
// 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.
