<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Is there a way of filtering vtkPolyData so that singleton
points are removed? By this I mean that if a point is greater than a distance (
say x ) from it’s nearest point then it should be removed from the points
list. Just a thought: maybe it could be a subclass of vtkCleanPolyData if you
could somehow specify the points as unused.</span></font></p>
