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.
