Detailed Description

Place points on the surface of polygonal data.

vtkPolygonalSurfacePointPlacer places points on polygonal data and is meant to be used in conjunction with vtkPolygonalSurfaceContourLineInterpolator.

Warning
You should have computed cell normals for the input polydata if you are specifying a distance offset.
