[kývýlcým helhel]

Hi everyone,
   
  I had some data that include only  x,y,z information of points.I need to find the normal of each point.I try to use vtkPolyDataNormals but it finds normals with polygons so it did not useful for me.Is there any class or any way to fid point normals??
   
  Thanks...
