I think the Hausdorff distance is the most appropriate indicator. I applied the vtkDistancePolyDataFilter, but it gives me a much greater error than the one I get in the MeshLab (for Hausdorff distance). I understand that those measures are different, and the sampling has a different effect, so I would like to know if I should implement the Hausdorff distance by myself using VTK classes, or if there is already some implementation.</div><div id="yui_3_16_0_1_1446588682947_13831" dir="ltr">I found <a class="edited-link-editor" href="http://www.vtkjournal.org/browse/publication/839" id="yui_3_16_0_1_1446588682947_14327">this</a> implementation, but since I am using python bindings, I don't think this would work for me.</div><div id="yui_3_16_0_1_1446588682947_13831" dir="ltr"><br></div><div id="yui_3_16_0_1_1446588682947_13831" dir="ltr">Sorry for inconvenience and thank you all in advance.</div><div id="yui_3_16_0_1_1446588682947_13831" dir="ltr"><br></div><div id="yui_3_16_0_1_1446588682947_13831" dir="ltr">Best regards,</div><div id="yui_3_16_0_1_1446588682947_13831" dir="ltr">Darya</div><div id="yui_3_16_0_1_1446588682947_13831"><br></div></div></body></html>
