transform points and associated normals and vectors
<p>
<a class="el" href="a01728.html" title="transform points and associated normals and vectors">vtkTransformFilter</a> is a filter to transform point coordinates, and associated point normals and vectors. Other point data is passed through the filter.<p>
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 <a class="el" href="a01728.html" title="transform points and associated normals and vectors">vtkTransformFilter</a> actually modifies point coordinates in the visualization pipeline. This is necessary for some objects (e.g., <a class="el" href="a01302.html" title="sample data values at specified point locations">vtkProbeFilter</a>) that require point coordinates as input.<p>
