// .NAME vtkTransformPolyDataFilter - transform points and associated normals and vectors for polygonal dataset
|
|
// .SECTION Description
|
|
// vtkTransformPolyDataFilter is a filter to transform point
|
|
// coordinates and associated point and cell normals and
|
|
// vectors. Other point and cell data is passed through the filter
|
|
// unchanged. This filter is specialized for polygonal data. See
|
|
// vtkTransformFilter for more general data.
|
|
//
|
|
// An alternative method of transformation is to use vtkActor's methods
|
|
// to scale, rotate, and translate objects. The difference between the
|
|
// two methods is that vtkActor's transformation simply effects where
|
|
// objects are rendered (via the graphics pipeline), whereas
|
|
// vtkTransformPolyDataFilter actually modifies point coordinates in the
|
|
// visualization pipeline. This is necessary for some objects
|
|
// (e.g., vtkProbeFilter) that require point coordinates as input.
