<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hey Guys,<br><br>I am trying to extract curvatures from cloud points. I converted the cloud points to vtkpolydata format but vtkcurvatures didn't accept it, so I tried to use vtkTriangleFilter before vtkcurvature. it doesn't also accept vtkpolydata and vtkDelauny3D output. Any help would be appricited.<br><br>Thank you,<br>Sara <br><pre><br></pre></td></tr></table><br>
