<div dir="ltr"><div><div>Hello Tiago,<br><br>Using Fetch you should end up with a vtkPolyData object which have accessors to triangle point ids (using GetPolys() then a traversal on the vtkCellArray or directly using GetCellPoints(). Point coordinates can be retrieved using GetPoint() function. </div>So could you be more specific on how you call servermanager.Fetch() and what you are doing next to retrieve your normals?<br><br></div><div>Best,<br></div><div>Joachim<br></div><br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><b>Joachim Pouderoux</b><font size="2">, <font size="1">PhD</font></font><br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><font size="1"><i>Technical Expert - Scientific Computing Team</i></font><br><b><font size="1"><a href="http://www.kitware.fr" target="_blank">Kitware SAS</a></font></b><br></blockquote>
